Overview:
As some of you know, I have been looking for a set of in-ear headphones at a relatively high spec and low price recently and when Sennheiser suggested I reviewed the CX275s’ I was a little excited.
I have never owned a set of Sennheiser earphones, not because I didn’t want to or because I hated them but because they always seemed way outside the price I was willing to pay to listen to music.
It’ worth pointing out at this stage that I am anything but an expert when it comes to audio or audio accessories, I listen to music most of the day at work to drown out the noise of the office and when I’m working from home
I often have earphones in range to drown out the noise of the day.
My music tastes vary, I listen to anything from oldies all the way through to happy hardcore and rock in the middle so I needed an earphone that would suit all of the ranges I listened to as well as cover the audio podcast’s I listen to.
The CX275s’ were ultimately designed for use on a mobile phone however I was using them for a completely different purpose as you can tell
already.

Design:
Earpiece
The earpiece on the CX 275s’ are unlike traditional Sennheiser’s which are generally aluminium in build whereas these are a very hard plastic with a strange armadillo design an no Left or Right side indicators.
Cable
The cable is again a far cry from the more superior range and feels very flimsy and almost cheap. Made of a soft rubber they are sadly not tangle free and often get themselves into a bit of a mess.
Sound
The CX 275s’ offer a unique sound experience. Whilst very heavy on the lower tones such as base they are very lacking on clarity at the mid range and in my opinion they struggle to separate the mid level vs the top level when played at a comfortable volume level.
Review:
Like I said at the top of my review, I am far from a sound expert and whilst I love my music, I base my results only on my own experience and not at an industry professional level.
This may well sound very silly but not having the R and L on the earpiece was rather confusing and something which instantly annoyed me. I decided that the armadillo effect of the earpiece should point towards the back of my head and the smooth side out though to be honest it didn’t really matter as they are uncomfortable whichever way they are used when in the ear for anything over 30 minutes.
As far as the cable goes, not being tangle free has no effect on me at all, if anything I’m quite the master when it comes to untangling cables so please don’t let this be the driver for whether you buy these.
As you can tell I’m not a huge fan of these earphones, not because they have a poor cable, nor because they are pretty uncomfortable in prolonged usage but more because the sound of them at a low comfortable sound level simply isn’t to par with the what the brand stands for.
In short, if the music is at a loud level or you are listening to a dance type style of music then these are great however if you want to just chill out and listen to a bit of Dr Hook or Paul Simon then forget using these, they lack the distinction of the sound ranges needed to make for a great listening experience.
