## Customer Reviews

### ⭐⭐⭐⭐⭐ PS Portal Perfect
*by N***N on 29 January 2026*

Bought these for my PS Portal, adequate sound, perfect job.

### ⭐⭐⭐⭐⭐ Great solid performer
*by M***N on 23 December 2025*

Excellent earphones extra strong lead great sound

### ⭐⭐⭐⭐ 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.
