I can hear the other person crystal clear with no feedback or interference of any kind. They have full bass and clear mid-range and high notes. For its size, I consider the sound good (Bose had a slightly better sound but has a worse compatibility with WMP). So I researched & found these & decided to try. Que en realidad, son como 15 GB. It lasted for 2 days and on night two, I was crying at 3 a. No comparison. I would not say these are quality for the price they are. the mid and high are very good, perfect imaging and soundstage and very tight bass. Was very worried that by cutting the item, we would mess with the ease of use.
