Electronics : Jabra BT620 Blue Tooth Stereo Headset

Rating: - Long in the blue tooth ?
On the positive side, excellent battery life.

On the so so side, sound quality has varied for me, not so much maybe due to the BT620 as due to difficulty in getting device / PC to stay in high quality audio mode. That is because I am making VoIP calls (Skype and Microsoft Communicator) as well as listening to music from the same PC. One application wants to use low quality but microphone, music high quality, but rare getting them working together. Might be OK from a separate mobile, but why pay mobile costs when VoIP is free ?

On the negative side, microphone sound quality is poor. Making calls to mobiles are virtual impossible, even with mic sound cranked up to max on PC. As we sell VoIP services, I had to stop using the 620 as customers were saying "why are your calls such bad quality".

Rating: - Excellent sound quality, although could be smaller
I think bass and general sound-wise, these are excellent headphones. They're fairly comfy, and when paired with my laptop or Nokia N95, the sound is great. I used a Jabra A320s bluetooth dongle without problems on my laptop, although I've been having some problems with my new 64 bit windows desktop, where it seems to drop the connection every minute or so, which is annoying but I suspect this is a configuration issue rather than a hardware fault.

3 small niggles:
1. They're quite big - would be nice if they could make them smaller
2. They flash blue by default (although you can turn this off easily).
3. They're not comfy to wear around your neck for any period of time when you're not listening to them.

Rating: - Flakey bluetooth conection
I was given these for Christmas for use with my Samsung D600E which supports the A2DP profile. Connectivity has been , at best, reluctant , and on occasions non existent.

When I do eventually do get them to pair the sound quality is good, but frequently drops our of connection, requiring a complete reset. The pause/stop and track change buttons only work occasionally.

I have tried them with other phones and my PDP where the effect is similar.

Overall I am unable to recomend them and will be appraoching Amazon for a refund.

Rating: - Something to be aware of...
...I'm not reviewing the product as I never actually got to use it because of this A2DP bluetooth stereo issue. It is very important and if your phone doesn't support it, then, essentially one of the main advantages of the headphones is rendered redundant. My phone was the SE W810i and I read some online reviews of my phone that said it did support the A2DP protocol. Annoyingly, they were wrong and I took them at face value so ended up with these headphones. They seemed like they had good build quality and the USB cable allowed me to hear the sound quality too. It was all right but certainly worse than similarly priced jacked headphones. I'd make the sound quality sacrifice for bluetooth freedom only.

Rating: - Generally good, but have some strange quirks
I bought these to go with my Sony Ericsson w850i. Generally, I am pleased with them, but they do have a couple of flaws I have found.

Every so often, they will lose audio connection with the phone on track change and the buttons will also stop working. The only solution is to power off and on both the phone and the headphones - very irritating. Of course, this could be a quirk with my phone, but I can't prove either way. It is a chore though.

Also, they have a (comparatively) very loud minimum volume - in a quiet environment (e.g. my bedroom or office), they are actually uncomfortably loud. This is a really bizarre limit to impose.

Sound quality is good, but very bass heavy. I have been impressed with their battery life and the handsfree integration is great. The flashing blue lights every second when playing music I can definitely live without - the size of them means you look enough of a poser as it is - although this can be disabled, you have to do it every time you turn them on.

The sound leaks out quite a bit (combined with the volume means you'll probably end up being 'that guy' on the train) but this is a flaw of the over ear style and I would imagine not restrained to this particular model.

Overall, recommended, but not perfect.
