Bests & Worsts Reviews from Amazon

I'm in the phone industry (but I don't work for any bluetooth headset maker). I got a pair of these free from Altec before the product release. I like these better than competing models from Motorola, Jabra, Samsung and other brands. I have owned all of them. Reasons: 1) The non-rigid wire connecting the two allows for compact folding, and pocket stuffing. Most other brands don't offer that. 2) Sound quality is great, music sounds good. 3) Phone calls are great. With two ears to hear the call, I can hear people even when I am in a very noisy environment. The microphone isn't as good, so they may have problems hearing me if it is VERY noisy. Beware, many other brands of bluetooth stereo headsets only use one ear for phone calls - that's stupid and makes it relatively hard to hear. 4) Buttons do not get pushed by mistake. Jabra was terrible on this issue. 5) No stupid blue light show to make you look like a geek idiot. Jabra also was bad on this issue. 5.5) Overall, these are relatively discrete. You don't look like you have two big cans on your ears. 6) The charging plug type is Micro B USB, which may be new to you, but all new cell phones will standardize on this plug type in the 2010-2012 time frame. Negatives include: a) The earbuds fall off in your pocket, on the street, etc. I used a drop of superglue so as to prevent losing these. I recommend you do the same. b) As others have stated, don't sweat into them. I don't use for exercising, so not a problem for me. c) Caveat: Bluetooth inserts a small lag, which doesn't matter at all with phone calls or music, but with video can cause the audio and video to be slightly out of sync. Doesn't bother me, but be aware. If you want these for sport, consider the Motorola S9s, which are better with sweating. If you want to see a competing product that I also like a lot, which lets you use any headphones you like, but converts them into Bluetooth, check out the Sonorix C3.
