Q & As

Sennheiser CX 275s In-Ear Headphones with Microphone, Black 4.5 5 6 6
Superb sound Very pleased with purchase. Amazing difference in sound. 10 June 2014
Pleasantly surprised so far I was worried about buying new earphones but am very pleased I bought these. I did a lot of research so thanks to everyone else who has reviewed them. I have little ears and these fit without hurting! They also block out a lot of background noise so listening to music is a really lovely experience. They definitely give a much better quality of sound than the regular iPhone/iPod earphones. It is richer and has more depth. A good buy. 01 April 2014
Sleek and comfortable! These earphones are lightweight and comfortable- ideal for taking travelling or for use on the train. I bought them for my husband and I've been borrowing them ever since! 11 January 2013
Good sounds Good sound reproduction and very comfortable to use. 10 January 2013
A gift for son-in-law A perfect gift, Very happy with its performance! Small and compact. 10 January 2013
5 stars for listening to music... The best in-ear headphones I have used so far: top comfort and great sound. These headphones do block most of the outside unwanted noise... which can be a nuisance when using the microphone option as you can hardly hear your own voice! Listening to music on mi iPhone has reached another dimension. Shame talking over the phone using the headphones has become a frustrating experience, though. 09 November 2012
