## Description

Sennheiser cx 300s Universal Smart Remote Control In-Ear Headphones - Red

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.
Review: Comfy and good bass - I think these sound fantastic good bass, good noise cancelling and a comfy fit.

I think these sound fantastic good bass, good noise cancelling and a comfy fit.

### ⭐⭐⭐⭐ Ok for everyday use
*by C***O on 25 January 2022*

I liked these headphones, decent sound for everyday use and making calls. Negative is that you could hear throught the earphones when the cord was rubbing against something and they didn't last nearly as long as they should have with one ear losing sound after about a year.
