“Got this earphones for the sole purpose of working out/biking. Tested out multiple sports headsets (similarly priced), from sennheiser and bose. They tend to sound better, especially than the adidas sennheiser which sound pretty bad for the money. Great bass and clear mids and highs (considering it is bass-centric).

“This IEM is vocal oriented and so they are especially for vocal lovers. It is clean, detailed and upfront. This is not a basshead IEM instead it is punchy, detailed maybe a little slow on some really fast tracks but generally it is quite involving and fast. There is no midbass bloat I could hear so there is no veil in the mids. The guitars especially sound amazing on these...” --ozkan
