The best earphones I have had to date.The only drawback is that they are quite fragile.However Sennheiser have been great and replaced them for me.

The only negative thing to say about CX300 is that you have to demand proper studio time for the bands you are listening to. Every single detail in the recording gets through and nobody else but you would ever notice due to the size. But who cares, since the closure on the headphones allows you to focus only on whats inside your music player all noice is extremely well blocked. the perfect choice for everybody who wants to only listen to music and keeping the rest of the world outside without them knowing

gut!!!

These headphones are OK I have previously had Sony's before. I think I will be going back to them in the future. They just feel cheap, and should have gold fittings for this price

I purchased my CX300 about a month ago now and have been really impressed by them.I do a lot of traveling and there perfect for blocking out unwanted noise without having to crank up the volume. I did find them a little strange to wear at first but after a few days I got used to them and can’t imagine using anything else. The bass response is superb for an in-ear headphone and the design is pretty discrete so they’re not that noticeable when you are wearing them.Highly recommended to anyone who listens to music on the move
