Taotronics are competing against some big name, high cost wireless earphones, but these are good enough to make me wonder how the big names get away with charging three to six times the price.
These are neat and lightweight. They fit very snugly and comfortably and feel very secure. I workout very energetically, and they have never shown any sign that they would move, let alone come loose. The sound is, as with all in ear earphones, very dependent on how well you have them inserted in your ears and the eartips you use. I have found foams give good isolation; both Complys and InAirs work well, giving good, strong bass and clear treble. The soundstage and separation is very good too.
The battery life is claimed to be up to six hours and I see no reason to doubt that. They charge reasonably quickly.
As far appearance goes, there is no getting away from the fact that you do have a black box on your ears. They are not very large or obtrusive, and, of course, when you're wearing them, you don't see them. How much of a fashion icon that makes you is up to you.
They are easy to use, with three buttons on each earpiece to control all the functions you would expect. Pairing is straightforward and well explained in the instructions - which are, mercifully, written in clear English, unlike some of the garbled translations you get in some other far eastern products.
All in all, I am very impressed with the quality and value of these.
