I needed a pair of tws for every day use. According to reviews I watched, the Xtras have good sound. So I am writing to admit that this Bluetooth pair has a full and clear sound. Actually is better from a lot cheap iem's. The functionality also is unproblematic and easy to get used to.
The bass are very good. The kids clear and warm with male and female voices sounds amazing and not forward to the face. The highs also have air and cohesive.
For the price, is a bargain. They need deep insertion. Usually I use medium sized tips but I used the small ones that come with Xtras.
