Review: Sennheiser CX 300 In-Ear Headphones
How do these budget earbuds shape up?
(by editor © January 2009)

Seeing as many MP3 players come with cheap headphones so frightful that they make LCD Soundsystem sound like a drunk busker, spending a few bob on a decent pair can make a real difference to your sonic pleasure.


There's no shortage of interesting contenders, but after hearing many glowing recommendations from chums we decided to give the Sennheiser CX 300 in-ear headphones a go.

Available online for as little as £16 and coming in either discrete black or mugger-attracting white finishes, the Sennheisers immediately impresses with their packaging.

Built from what looks like a 3D cardboard puzzle, the cunning eco-packaging manages to be both aesthetically pleasing and superbly practical.

In fact, for the first time ever, the packaging drew a crowd around our desk as we folded back the layers to reveal the headphones inside. A really nice touch was the little badge that pops out at the end too. Great stuff, Sennheiser!



Once we delicately released the earbuds from their smartypants case, we noted that the construction quality appeared better than many of its rivals, with the earbuds solidly built and a good quality 1.2m flexible Y cable included. There were also two additional sets of soft silicon ear tips to help you get a good airtight seal inside your ear canals.

We were fine with the default medium set, but it's worth experimenting to get the best fit because the bass performance relies on you getting a tight lug'ole seal.

Once you've wedged the earbuds in, you'll enjoy a reasonable amount of noise isolation which might come in handy if you have to suffer a boneshaker bus commute every day.




It's worth noting that some people can find the noise isolation a bit uncomfortable, especially when they're walking around.

They're clearly not a good idea for cyclists and joggers who need to be aware of what's going on around them.

Putting the Sennheiser CX 300s up against some of the pricier in-ear headphones, we were pleasantly surprised by the sonic quality.

The soundstage was clear and crisp, the voice had none of that horrible boxiness you can get with cheaper ‘phones and the earbuds handled a wide range of music with aplomb. The bass handling was pretty good and the headphones were plenty powerful too.

Considering the low price and overall build quality, we think the Sennheiser CX 300's are an excellent budget choice and almost certainly a vast improvement on the earbuds that come bundled with most consumer MP3 players. Do your ears a favour and give them a go.
