The unit is powered by USB, but it can also double as a USB-connected external speaker as well as a Bluetooth speaker

Bluetooth stopped working and it is basically a paper weight for me.

I've also used with my cell phone for some conference calls and the Bluetooth works excellent and very easy to setup and use.

Long battery life...nice bluetooth to phone option

I have been using this for 6-10 meetings a day in my home office, connected via USB using mainly Skype, with the odd Bluetooth call

Trying to isolate the problem, we disable bluetooth to make sure it was not the phone or carrier, it was clear the issue is the device

Definetly the best bluetooth speaker phone

It seems Jabra has expanded on their excellent Bluetooth devices for use in automobiles and come up with this great product

This bluetooth speakerphone completely exceeded my expectations.

And of course it allows for direct connectivity via 3.5mm phone jack if Bluetooth is unavailable

Works well with both USB and Bluetooth, when charged it is also a nice Bluetooth speaker for travel.

While this might be a good bluetooth speakerphone for the car, there is no visor clip to affix.

Love it so far - good sound quality, easy to set up (I have the Jabra link 360 for Microsoft Lync support) and great range - almost too good since my phone still picks up the Bluetooth well outside of the room.

I've bought the Anker brands and other affordable versions of speakerphones but they are fragile, lack a decent dynamic range and sometimes come with awkward controls or poor bluetooth connectivity (e.g. Bluetooth

The sound quality (both speaker and microphone) is better over USB and definitely deteriorates over bluetooth.

Awesome Bluetooth speakerphone

A super-loud Bluetooth speakerphone with omnidirectional Mics

Great Bluetooth and PC speakerphone interface

The Bluetooth feature on this works great with my Windows Phone and my Windows table.

This thing sounds better (on both ends) than any other conference speaker I've used, is inexpensive, and also serves as a great bluetooth connection as well, so I can receive calls from Google Voice and my phone without any need to swap around.

Bluetooth worked flawlessly and the voice clarity overall was very good

I have had no problems with people hearing me and the speaker is almost as good as a dedicated bluetooth speaker if you want to play music.

Best bluetooth connection

When I disabled Bluetooth the issue was resolved

The bluetooth and battery operation of this new 510 are great improvements

Most iPhone users have come to love Bluetooth and all the wonders it can perform, and Jabra SPEAK is wonderful

Bluetooth works perfectly with my phone.

Bluetooth is such a lifesaver and all devices that connect in such a way are simply great

Side benefit is using Bluetooth for music from the iPhone.

Another great Jabra bluetooth gadget in my gadget bag.

This model also has a nice Bluetooth feature and a rechargeable battery, so it can be used even without a computer.if you are looking for a plain Jane good mic/speaker combo for computer use via the USB, get the 410.

This is a very reliable bluetooth speakerphone with good battery life, and is very easy to connect, recognized instantly by Mac in both USB and Bluetooth mode

Really nice Bluetooth speaker

Bluetooth didn't work very well--tried it on a number of computers

If all you're going to do is use this tethered, the cheaper non-Bluetooth version is well worth it.

It pairs easily with my bluetooth and the sound is crystal clear.

Easy Bluetooth pairing with Clear transmit and receive audio

I was very impressed by the Jabra Solemate, which is their portable bluetooth speaker designed for music

Brilliant crystal clear Bluetooth quality.

The reason I purchased this model over the less expensive non-bluetooth version was for use with my iPhone while on the road.

Reduces background noise and echo, clear sound, and bluetooth make this a winner.

Bluetooth also works as advertised.

The Bluetooth is excellent and I highly recommend.

Excellent sound and easy Bluetooth connectivity

I love the easy to ready indicator lights - battery life, bluetooth connect, mute, etc.

I especially like the indication lights on top (bluetooth, mute, battery life, power).

The bad:Bluetooth microphone level significantly worse than USB.No way to adjust mic gain

I use it as a soft-phone (plugged into my laptop/used for web conferencing) and as a bluetooth to my cellphone

I don't know how well Bluetooth works for other devices but it is not usable for the Mac

I think this is a really nice Bluetooth speaker.

Works across devices (including bluetooth on my phone) and gives me the hands free experience I've been looking for at my desk.

n’t get very loud.
