So we just got a pair of Sennheiser CX 3.00 headphones through the door and we’re excited. We have tried and tested Sennheiser products before and the results have been very good. Will these new in ear headphones live up to the reputation? Lets find out. Sennheiser specify the following features:

  • Earphones with detailed sound and enhanced bass
  • Optimum fit in the ear canals and high attenuation of ambient noise
  • Elliptical, tangle-free cable
  • Convenient carry case included
  • Available in black, white or red
  • 2 year warranty

Some nice features, especially the ‘tangle free’ cable as we all know this is a constant problem when removing headphones from your pocket or bag. Out of the box the headphones look and feel really good, they are relatively small and lightweight and the 1.2m cable included is a good length. You also get a variety of ear bud sizes, XS upto Large, which should cater for every type and size of ear, aswell as a nice carry case to keep your headphones protected.

I tried out a couple of the different ear bud surrounds and found that the small was the best fit for me. When inserted, the headphones were snug and secure and they were comfortable to wear. I was able to move my head freely while joging and the headphones stayed put. The cable was long enough to comfortably put my music device in my jean pocket. There was plenty of spare cable to allow for movement. The cable terminates into a 3.5mm gold plated jack plug.

As these are in ear headphones, you would expect a degree of sound isolation as the bud physically sits within your ear and the CX3.00 doesn’t disappoint. You definitely get a feeling of isolation when the headphones are in. The CX3.00 perform well. I listened to a variety of songs at high quality and really enjoyed what I was listening to. The sounds were dynamic and precise, I could hear specific sounds such as cymbals from a drum kit easily. There is positive dynamic range, with a beautiful mix of treble and mid and more than enough bass, maybe too much for some listeners but it didn’t hinder my listening.

The CX3.00 headphones can be picked up for around £40 in the UK and come in a couple of finishes. At this price, we recommend these headphones for most uses, especially flights, for the good sound isolation. You can pick these up from most online retailers or direct from Sennheiser.
