I bought a pair of Soundpeats earbuds (very inexpensive), they fitted well but sounded tinny (even for a non-audiophile). Then I purchased a slightly more expensive pair of Taotronics and they were very poor (never fitted well, poor Bluetooth connection, and the worst sound). The Taotronics made me hesitant to buy another pair, but reviews of the 1More were good and they were on special. Wowzer, great fit, the connection has not dropped and I can walk about 15m-20m away from the device and still receive a signal. The best part is the sound, I was looking for something with a little bass, but many earbuds promoting bass are like car disc brakes in size. The 1More's are a standard size and have just enough bass not to sound tinny. I needed to wear them for about a three-hour session recently and they felt comfortable throughout. Highly recommended. NB: I have not tried firmware updates, etc, straight out of the box and very happy.
