Hands on Review of the Jabra SP700 Bluetooth Speakerphone

I have used a few Bluetooth Visor Car Kits in the past only to find sooner or later (more sooner), I retire them to the Bluetooth graveyard located in a dark corner in the spare room at home. It always begins on a high with a promise to provide a Hands-free but safe, convenient , compact, foolproof and law abiding way to receive and make calls while sitting in the comfort of a stationary or moving vehicle… However, eventually the honeymoon gloss fades and cracks appear to what first seemed a win, win situation.

Jabra SP700 Bluetooth Speakerphone

So when presented with the opportunity to try yet another Handsfree Bluetooth in-car visor product I did not climb over the office furniture or rugby tackle fellow colleagues to be first in the queue. However on this occasion a particular feature of the Jabra SP700 caught my imagination – it claimed to offer both voice and stereo music streaming direct from my Bluetooth enabled mobile phone to my in-car entertainment unit.

In the Box

The compact and stylish Bluetooth speakerphone also comes supplied with a visor clip that is already fitted, a USB charger cable, USB car charger and plain English and compact user guide.

Getting Started

Just connect the USB charger cable to a spare USB port on your computer and up pops an illuminated red battery icon to indicated that it is charging. When fully charged this icon then changes to green. If you do not have easy or regular access to a computer then think about purchasing a USB Mains Charger and use the USB charger cable provided in the box when not in the car. On the front of the unit are a range of icons that illuminate to indicate what status the speakerphone is in. I will discuss these in detail later.

There is no dedicated off/on button, and although not immediately obvious, this function is activated by pressing and holding the front of the speakerphone; 2 seconds to switch it on and 4 seconds to switch it off. If like me, you tend to exit your vehicle and forget to switch the speakerphone off then do not worry, the SP700 has an auto-power off when the phone is out of its Bluetooth range.

Pairing the SP700 to your mobile phone couldnt be easier; when you switch it on for the first time it automatically enters its pairing mode which is clearly indicated by an illuminated Bluetooth Status icon appearing. Next, just activate the Bluetooth function on your phone and set the phone to discover the SP700, enter the pin code (0000), mount it to your car visor and youre good to go!

Controls

Now the SP700 is not big on controls, I have already mentioned the lack of an on/off button and it does not have any audio adjustment controls aside of a volume up & down button on one side of the unit, and there is also a FM transmitter button located on the opposite side.

Features

Now the SP700 provides the basic functions like any other like handsfree kit, as well as supporting extended features of some phone models like voice dialling which as you may have already experienced is a potential Olympic Linguistic event in its own right. Also the SP700 features advanced noise reduction and echo cancellation that insures excellent sound quality on both sides of the call.

When using the SP700 the current status is clarified by a clear voice announcement available in 10 languages a treat no doubt for those multi lingual potential users out there or those wanting to practice some basic phrases before arriving at their international holiday destination this summer!

The voice announcer switches from a female to a male voice for different status alerts. However the announcement that caught me by surprise was the one that announced the caller ID of an incoming call brilliant and by pressing the front of the speakerphone I could answer or end the call. The announcer also confirms when the speakerphone is switched off and also when it has made connection with your mobile phone.

I found the clarity of the incoming call to be excellent by comparison to other Bluetooth visor speaker phones that I have used in the past, and I can confidently say that my voice was clearly received by my caller. I must admit that my vehicle suffers from very little cabin noise generally – however I also tested it in my wifes 1.4 about town vehicle which isn’t a tractor by any means – but with mischievous and noisy kids in tow I still found the SP700s speakerphone to be equally as impressive.

The Jabra SP700 has a classic, slim line design

The best feature is the FM transmission – A simple press of the FM transmission button illuminates the FM transmission icon and speakerphone mute icon, then kicks the voice announcer into action as she clearly tells you the FM frequency to tune your car radio to. If this frequency is congested by existing radio stations then you can make adjustments by 0.1MHz at a time using the volume keys, the announcer will recite the new frequency selected each time you make a change. My radios RDS function displayed the word JABRA to indicate that I had sourced the correct frequency and I promptly saved it to a spare preset number. This remains the fixed FM frequency unless you make a change as previously mentioned or reset the unit to factory settings. The only thing I did not have time to test was how the selected FM frequency would stand up to long journeys whereby you may drift into localised radio stations sharing the same frequency; however, the ease I found in changing frequencies leaves me quite confident that such an event occurring would not be a major problem to resolve.

The Nokia E71 phone was used to test the SP700 for streaming music to my car stereo, on hitting the play button on the phone, music came belting out almost immediately through the car speakers. The quality was fairly good, however I found that the SP700s lack of audio controls came to haunt it as the volume controls previous used to adjust the FM frequency remain set to this function while in FM transmission mode, so you have to rely on your in-car audio controls to equalize the sound and adjust the volume. This sometimes is a problem when you switch back to the radio or CD mode as the volume can sometimes be far too high for those built in sources.

Taking calls using the FM transmission mode was a delight, however be aware that your calls may be picked up by a stranger who is tuned to the same FM frequency and in close proximity to your vehicle, so keep this feature just for music or calls that are not of a private or sensitive nature. On a final point if you turn off your radio or forget to change the status of the SP700 back to its own speakers, then the SP700 automatically disconnects from its FM transmission status following a period of non-use.

The SP700 boasts up to14 hours talk time & up to 255 hours standby however after a week of testing I am yet to re-charge.

Conclusion

I must admit the SP700 has not changed my preference which is to avoid taking calls while driving if I can, however when circumstances dictate that this is unavoidable or for those of you or where this is a day to day necessity then the SP700 does not disappoint, mainly because of its ease of use, functionality, portability and quality. The Ace up its sleeve however is the FM transmission that adds a more practical and up to date feature for all music lovers who have migrated their favourite playlists into the fashionable multi-media Bluetooth mobile phones that are currently available a smart move by Jabra.

Samsung SBH-650 Stereo Bluetooth Headset Review

Stereo Bluetooth Headsets haven’t always been the most popular accessory in the world, but now that mobile phones are becoming focused on music and video playback, more and more people are finding a need for a way to listen to their music in stereo, but without wires tying them to their phones.

Stereo Bluetooth Headsets allow you to listen to your music over a bluetooth connection and generally have a range of around 10 metres. This means that you can put your phone down and wander freely around your house with out having to take your phone with you – great if your phone is on charge but you want to listen to your music without having to sit on the floor next to a plug socket!

The big names in Stereo Bluetooth headsets tend to be Sony Ericsson, Nokia and Jabra as these all tend to have a large range of headsets available. Other manufacturers such as Samsung also make stereo headsets but tend to concentrate on just a couple of models, and I’m going to review one of them here – the Samsung SBH-650 Stereo Bluetooth Headset.

What is Bluetooth?

Bluetooth is a way of wirelessly transferring data from one device to another. Bluetooth first appeared around ten years ago as a quicker and easier method of data transfer than infra-red. With infra-red you had to point two devices together in order for it to work (the same way as you have to point your television remote at your TV.) There were a number of problems with this kind of connection; it was unstable, slow and limited in its uses.

With Bluetooth, you no longer have to line up two devices, you just simply turn on Bluetooth and send to the device you want. Bluetooth technology was initially used for personal hands free kits. The lack of wires made it much more convenient especially when driving. Over the last few years as prices have fallen and phones have advanced, Bluetooths increasing range and even faster speeds has meant it could be used for far more than just hands free kits.

Bluetooth Classes
There are different Bluetooth Classes which give an indication of the range over which data can be transferred:

• Class 1 up to 100m
• Class 2 up to 10m
• Class 3 – less than 10m

In order to achieve data communication at these distances you will need both devices to be from the same class.

So what can it do?
Bluetooth is most commonly used for transferring pictures, music and ringtones between phones and connecting to Bluetooth headsets, personal hands free kits and car kits. As more and more phones become multimedia handsets, Bluetooth can also be used to stream music in stereo to wireless speakers and car kits using A2DP technology. With the introduction of Internet Telephony, Bluetooth headsets are now being used with Home PCs to enable wireless calling.

What Bluetooth Devices are available?

Listed below are some of the most popular types of Bluetooth devices available.

Bluetooth Dongles

Bluetooth Dongles
Bluetooth dongles vary in size, range, and specification. When choosing your dongle its important to consider that not all dongles support all bluetooth functions. Bluetooth Dongles have a range of up to 10 metres or up to 100 metres. If you are looking to connect a Bluetooth headset to make and receive voice calls you will need to make sure it supports the Headset and Handsfree profiles. See the Bluetooth glossary for information on Bluetooth Profiles.

Mono Bluetooth Headsets

Personal Handsfree
The Conventional Bluetooth Headset. These come in a range of shapes and sizes, but what should you look out for when choosing one? Most headsets have the same features; they will answer and end calls, dial the last number you called and activate voice dialling on your phone, as well as adjust the volume of the speaker. The main differences are battery stand by times, weight and call quality.

Stereo Bluetooth Headsets

Stereo Handsfree
A fairly new device in terms of Bluetooth headsets. With a stereo Bluetooth headset you can connect it to a compatible Bluetooth device and have your music play in stereo the same as it would through normal stereo headphones but without the wires. When a call comes in your music is paused while you take the call and resumes when the call is over. You get all the same features as a standard Bluetooth headset, but depending on the model you may get music control features too. For stereo streaming your phone will need to support the A2DP profile. To control your phones music playback your phone will need the AVRCP profile. See the Bluetooth glossary for information on Bluetooth Profiles.

Bluetooth Simple Car Kits

Simple Car Kits
Simple Car Kits are becoming an extremely popular way of safely using your phone whilst driving. With no complicated installation needed, simple Bluetooth Simple Car Kits are battery powered and are normally clipped to your sunvisor or sit in you cars cigarette lighter socket. These give you the same control over your calls as a personal handsfree but instead of sitting on your ear, they act as a loud speaker in your car. More advanced models will have an LCD screen so you can see the name or number of who is calling you.

Multimedia Bluetooth Simple Car Kit

Multimedia Simple Car Kit
A lot more simple than the name suggests, these have exactly the same functionality as a standard Simple Car Kit, but with a built-in FM Transmitter so you can attach your MP3 player by cable or stream music via Bluetooth from your phone through to your car stereo for high quality sound. Depending on the kit you chose, you can have the callers ID or song information shown on your car stereo display. For stereo streaming your phone will need to support the A2DP profile. To control your phones music playback your phone will need the AVRCP profile. See the Bluetooth glossary for information on Bluetooth Profiles.

Professionally Installed Bluetooth Car Kit

Professionally Installed Car Kit
Professionally installed car kits will give you the best possible experience while using your phone hands free in the car. They have a separate speaker and microphone, and with some extra adapters can be routed through your car stereo. Most Bluetooth kits have an LCD screen so you can see who is calling before you answer. Some kits will also allow you to transfer your phonebook contents to the car kit so you can make calls with out having to touch your phone at all.

Professionally Installed Bluetooth Multimedia Car Kit

Professionally Installed Multimedia Car Kits
As the name suggests, these have exactly the same functionality as a professionally installed car kit but as they are connected to your car stereo you can stream music from your phone or MP3 player for high quality sound. Multimedia Kits will normally give you full control over your music and some will have the option to connect non-Bluetooth MP3 players. For stereo streaming your phone will need to support the A2DP profile. To control your phones music playback your phone will need the AVRCP profile. See the Bluetooth glossary for information on Bluetooth Profiles.

Bluetooth GPS Receiver

Bluetooth GPS Receiver
Sat Nav is the latest must have device on your mobile. Bluetooth GPS receivers can add Sat Nav functionality to your phone. The features on a GPS receiver are pretty standard and the only things you would need to bear in mind are size, weight and most importantly compatibility with your phone. Not all handsets will support the required GPS software.

Bluetooth Stereo Speakers

Bluetooth Speakers
Bluetooth speakers offer the same kind of functionality as Simple Car Kits but are designed to be used in the home. Some models have LCD displays that can display album art and keys to answer – end calls. For stereo streaming your phone will need to support the A2DP profile. To control your phones music playback your phone will need the AVRCP profile. See the Bluetooth glossary for information on Bluetooth Profiles.
Other Devices
The list of Bluetooth enabled devices is growing all the time. Other devices that now come with Bluetooth technology include cameras, camcorders, keyboards, mice and photo frames to name a few.
Bluetooth Glossary

This Bluetooth Glossary will explain more about the different profile types and help you to understand bluetooth compatibility.

Advanced Audio Distribution Profile (A2DP)
The A2DP profile describes how stereo quality audio can be streamed from a media source. A typical usage scenario can be considered as the walkman class of media player. The audio source would be the music player and the audio output is the wireless headset. A2DP defines the protocols and procedures that allow the distribution of high quality audio content in mono or stereo.

Audio/Video Remote Control Profile (AVRCP)
AVRCP is designed to provide a standard interface to control TVs, Hifi equipment, etc This profile is used to allow a single remote control (or other device) to control all the A/V equipment that a user has access to. AVRCP defines how to control characteristics of streaming media. This includes pausing, stopping, starting playback and volume control as well as other types of remote control operations.

Bluetooth Profiles
Bluetooth profiles are general behaviours through which Bluetooth enabled devices communicate with other devices. Bluetooth technology defines a wide range of profiles that describe many different types of use cases. In order to use Bluetooth technology, a device must be able to interpret certain Bluetooth profiles. The profiles define the possible applications.

Dial-up Networking Profile (DUN)
DUN provides a standard to access the Internet and other dial-up services via Bluetooth wireless technology. The most common scenario is accessing the Internet from a laptop by dialling up on a mobile phone, wirelessly.

Generic Object Exchange Profile (GOEP)
GOEP is used to transfer an object from one device to another. The object may be any object such as a picture, document, business card, etc. The profile defines two roles, a server that provides the location from which an object is pulled or pushed, as well as a client that initiates the action. GOEP provides a generic blueprint for other profiles using the OBEX protocol.

Hands-Free Profile (HFP)
HFP describes how a gateway device can be used to place and receive calls for a handsfree device. A typical configuration is a car using a mobile phone as a gateway device. In the car, the stereo is used for the phone audio and a microphone is installed in the car for sending outgoing audio of the conversation. HFP is also used for a personal computer to act as a speakerphone for a mobile phone in a home or office environment.

Headset Profile (HSP)
The HSP describes how a Bluetooth enabled headset should communicate with a mobile phone or other Bluetooth enabled device such as a computer. When connected and configured, the headset can act as the remote devices audio input and output interface.

Human Interface Device Profile (HID)
The HID profile defines the protocols, procedures and features to be used by Bluetooth enabled HID, such as keyboards, pointing devices, gaming devices, and remote monitoring devices. Sony Ericsson handsets support the HID profile.

Object Exchange (OBEX) Protocol
OBEX is a transfer protocol that allows devices to exchange files, such as Images, Videos and Music Files

Pairing
The process of establishing a new relationship between two Bluetooth enabled devices. During this process a passkey is exchanged either before connection establishment was requested or during connecting phase. Some devices will need to be put into pairing mode before pairing can begin.

Passcode
When pairing devices, it is strongly recommended to use a pass code to authenticate incoming connections. Also, in certain connection situations you may desire additional assurance that you are connecting to the device or person you expect. A pass code can normally be any combination of keys (letters or numbers). Do use caution as some devices do not map characters similarly. Passkeys are valid only for the connection and may be different for other devices or users.

Personal Area Networking Profile (PAN)
PAN describes how two or more Bluetooth enabled devices can form an ad-hoc network and how the same mechanism can be used to access a remote network through a network access point. The profile roles include the network access point, group ad-hoc network and personal area network user.

SIM Access Profile (SAP)
SAP allows devices such as car phones with built in GSM transceivers to connect to a SIM card in a Bluetooth enabled phone. Therefore the car phone itself does not require a separate SIM card.

Synchronization Profile (SYNC)
The SYNC profile is used in conjunction with GOEP to enable synchronization of calendar and address information (personal information manager (PIM) items) between Bluetooth enabled devices. A common application of this profile is the exchange of data between a PDA and computer.

Pairing Mode
Most Bluetooth devices will need to be put into pairing mode before it can be linked to another device. During pairing mode the device will send out a signal that will allow it to be found by the device that is trying to link to it. By having a pairing mode it prevents unauthorised users from accessing a device.
