## Description

Sennheiser cx 300s Universal Smart Remote In-Ear Headphones - White

Review: Great solid performer - Excellent earphones extra strong lead great sound
Review: Great Ear-canal Headphones. - Note 1: This is only the 2nd pair of ear-canal headphones I have used. Note 2: I have bought these for music listening purposes only. Pros: They are lightweight, comfortable and come very well packed. They have good length of cord and provide very good sound from: cassette player, Android Phone and mp3 player (Boom!). Was very impressed. There are numerous ear tips supplied but I found Aiivioll Silicone Ear Tips give more bass and fitted my ears better. I found also that you do not need high volume as they have high sensitivity. This means the battery driven or rechargeable devices should be able to play for longer. Cons. Wire noise can be experienced when cable banged/tapped due to high sensitivity.

### ⭐⭐⭐⭐ 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.
