Summary: My co-worker and I both use the Jabra 510 for work. It is flawless for conference calls. There is no "tell" that an open air speaker is in use. I also use this speaker on my various devices within the house pairing either via bluetooth or tethered to my laptop.
Summary: I was also excited about this product, as I work from home and wanted a speaker option. General features and connectivity was great, it looked good, the battery lasts forever, but when I started making calls, the other line complained about an echo effect.
Summary: Sound quality is good when used either as 1) a bluetooth speaker for music and 2) for voice calls. The flat-buttons are sometimes hard to deal with, compared to real buttons that depresses, but eventually you will get used to it.
Summary: I am very impressed! Works well with my iPhone 6. Sound quality is clear and does even better than my wired teleconferencing speakerphone. The device is also easy to use and a full charge lasts for quite a while. I've had it for 6 weeks and so far I have no complaints or issues. Great product!
Summary: This thing started out SUPER. But now I'm 3 months using it and the speaker is starting to go. People on the other end say I sound great. But on my end, the speaker is severely crackling, sometimes, but increasingly.
Great Call Quality and Easy/Automatic Bluetooth Pairing

Summary: Wonderful call quality and the device pairs very well to my mobile device. The speaker volume isn't quite as loud as I'd like it to be during those rare calls where the other person seems distant, though for almost all other conversations it's very good.

Summary: I rarely gush over gadgets. This one is exceptional. It does exactly what it is designed to do and has an excellent design. Calls are clear for both sides of the conversation. Love the touch sensitive controls for all features.
Summary: I use VoIP through Cisco Jabber almost daily, and had been using a much more expensive but found that on conference calls, I couldn't get it loud enough for personal use -- let alone use with multiple people. I gave this a shot, and was very happy.
