### ⭐⭐⭐⭐⭐ Nice sounding
*by M***T on 24 April 2026*

These are great and very reasonably priced

### ⭐⭐⭐⭐ Good sound quality,well made.
*by P***P on 5 June 2025*

These wired ear buds give well rounded sound with a bit extra bass. A good seal in ear is easy to achieve with the selection of silicone cups that are in the box. As a result outside noise is interference is markedly reduced. Cable entanglement is not a concern due to the type of cable used. The in-cable switch start/stop and track advance works well. My only niggle is the 3.5 mm jack is in some cases a bit tight to plug in or remove. Overall a good product in my opinion.
