Not built to last. The rubber cord has stretched and now one of the buds has stopped working. Expected them to last longer than a year.

Though I'm sure there are better headphones out there at the $100+ range, these are awesome for the price. The sound quality is great, and they block out more outside noise than any buds I've ever had.

Excellent quality sound and comfortable fit could do with being a bit louder but you are governed by your device volume settings

Not a music (& technical) geek but can say that they have great sound isolation; Work perfectly fine for using them on air planes without blasting your ear drums on the highest setting for hours.

More colour options? The red was nice; but other colours would be much appreciated

These earphones were bought for the purpose of onstage monitoring for a musician and they have more than exceeded there expectations due to the perfect amount of noise cancellation. They work great for everyday music listening too which makes them a great buy for semi professional and casual use.

sound signature was not exactly my cup of tea; but i can see its appeal

Very nice, loud and you can control the volume from your hand set. Love it!

The sound is quite good and the noise cancelling works well with the sound at a reasonable volume. With that said, I've gotten spoiled by using other headphones designed for use with Apple devices so not being able to pause or skip to the next song with these headphones made me sad.

The Sennheiser CX 3.00 in-ear headphones are a mid-priced model designed for use by the general listening public. The earphones are an update on the Sennheiser CX 300 II model, which was popular with consumers and generally well-received. I have used the CX 300 II for a number of years and [...]
