## Description

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

Review: Comfy and good bass - I think these sound fantastic good bass, good noise cancelling and a comfy fit.
Review: Great sound and tough - The sound is excellent, you can buy better quality sound but it is at least £20 more expensive and will not be as rugged. I have been through loads of in ear headphones as I listen to audiobooks and music all day and they usually die due to being caught on something or having appallingly shoddy connections to the cables that fray. Whether expensive or cheap they have all failed in less than a year, Soundmagic, Betron twice, Sony, a pack of three cheapies and five Sennheiser until this pair of Sennheiser CX300S. Obviously quality has improved. If I was to niggle about something, the cable is a bit long but that will be a plus to some people
