The Sennheiser CX300 headphones perform well and are noticeably better than stock earbuds. The sound is geared more towards the bass end of the spectrum, though the highs are relatively sharp. A slightly fluffy midrange is the only drawback, sound-wise. They are a comfortable fit and the headphones are supplied with small, medium and large rubber inserts for optimum comfort.

However, I have been through 3 pairs in 2 years, as they have all stopped working in one ear. The problem seems to be that the mesh cover inside the earphones seems to be particularly prone to clogging up with wax. Other in-ear designs avoid this by having a long channel between the earphone and the ear canal, which can be cleaned. Once dirty, the CX 300s are impossible to clean and I am sure that this contributed to their short life.
