Blueant S4 Bluetooth Stereo Speaker

The S4 has a lot of good qualities. Excellent battery life, solid microphone and speaker, and it responds well to commands...if it responds at all.

My wife has the exact kind of voice for which voice recognition systems (Google voice search on her phone, or the S4 in this case) are NOT designed. She can't get it to respond to her voice to start up the process. Once it asks her to "say a command," then she can say "phone commands" and make a call. But she can't get it to activate while it's just listening, passively. Meanwhile, I'm in the passenger seat and can get it to work while speaking softly. In terms of voice recognition systems, my voice is perfect for them. So...it works great for me, not so much for her.

The microphone and speaker are great. The included micro USB cable is ridiculously short, but I guess they're thinking you would use the cigarette lighter adapter and not want too long of a cord in your car while charging. I just charge it at home overnight, and it lasts for days and days, even if left on by mistake for much of that time.

One thing to note you tell it to use "phone commands" and then it activates the phone's command system. It is merely a speaker and microphone for that system despite the whole "import contacts" it is not doing recognition itself. The phone is. So if you have a bad (or badly designed) voice dialing system on your phone, it'll be just as bad with the S4. I have an HTC Incredible and that's great. My wife has a Droid X and its need for one more level of confirmation slows her down. My rooted EVO 4G, for work, is somewhere in between. But that's the phone, not the S4.

The Blueant S4 missed the mark. The have used other devices and decided to upgrade. I bought the S4 and I am so disappointed. The quality is lacking, the commands are silly and hard to use and I have to speak the commands several times to get the S4 to select the right one. 2 out of 3 times it selects the wrong person from my address book and that SILLY trigger "BlueAnt speak to me" is driving me crazy. Not worth the money.

I am surprised by some of the negative reviews. I have had this device for a couple of years now and I use it every day and love it. No one ever complains that they can not hear me and I can always hear others clearly. I keep it mounted in my car and always easily have hands free talking without having to clip anything to my ear. I wold highly recommend the device. Becasue I have two phones connectted at all times (work and personal), I use the activation of the voice dialing from my phones not the Blueant device so I can be sure which phone is being selected to call from. That seems to work best with two phones connected.

Works well. The first one died a few weeks into use. Blue Ant was outstanding and fast replacement. A very good speaker!

I've had this product for over a year now. The "true" handsfree worked great for the first 9 months. Then I began experiencing problems whereby the Blueant device's handfree feature could not hear me. I continued to use it for a few more months but would have to push the multifunction button so that I could speak to it. Close to 12 months after purchase, the listening mechanism stopped functioning altogether. I couldn't dial out unless I dialed through my Blackberry. I got an RMA and obtained a replacement. The replacement was brand new in a box...I was very surprised. Everything began working again. Now, another 6 months into it and the handfree feature is starting to breakdown again. I have to use the multifunction button to dial out.

I have other Blueant devices and they work great. It think there might be a reliability issue with the S4.
