Sennheiser CX 275s


The Sennheiser CX 275s combines serious bass response with a light, secure design, but these affordable earphones are not for everyone.

Powerful, distortion-free audio performance with deep, boosted lows. Inline remote control and microphone for mobile devices. Comfortable, secure, lightweight fit

Can sound tinny or harsh at times. Boosted deep bass response not for purists. Inline remote has no volume controls

The Sennheiser CX 275s is an earphone pair geared towards the bass lover on a modest budget. At $69.95 (direct), it's neither cheap nor over-priced, and offers solid, distortion-free audio performance. The boosted lows will scare away purists, and even...

Sennheiser CX275s Review


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' ...

Sennheiser CX275s


Capable enough but these Sennheisers don't quite justify the price

Balanced ; Well organised ; Comfortable fit

Fiddly ; Timing could be better ; Clumsy presentation

Sennheiser CX 275s review: verdict Overall, the CX275s feel a little clumsy. All the elements are present and accounted for, but they need to perform better together to create that sense of quality and panache.

Sennheiser CX275S


At around £30 in stores, these Sennheisers are the cheapest pair of headphones in our gruelling audio quality group test. Yet the CX275S perform admirably, making it down to the final three. They tip the scales at just 15g, but are still capable of...

OK for the price


If you can avoid it, try not getting anything from Action Packaged Inc. They were really slow processing my order, I couldn't get a hold of anyone who could help me cancel my order over the phone and they completely ignored my emails. *The three stars...

Low profile, so wearing ear muffs/180's doesn't make it uncomfortable ; Mic is a great feature on nose isolating earphones

Mids and highs aren't all that great. A lot of songs sound muffled and it's not something an equalizer can completely fix ; Cord tangles really easy ; Do not spend anything more than $80 on these

somewhat satisfied


-I have and in window ac unit and my 65w 2.1 speakers won't take the noise away completely (My 300w stereo will) anyways, these earbuds, I put on, and I hear just a little hum, as soon as you put music on, even on the lowest volume, you are pretty much...

Amazing sound - never heard earbuds play anywhere close to this ; I would say, well packaged, and I don't say that often ; Carrying bag is a nice touch, although pretty useless thing for me ; The sound is amazing ; Mic works well, if not windy ; The...

the only con I can find is the cord, it is so thin , the 3.5 jack is kinda flimsy too. I mean, it is so thin, that you are scared to pull it out of your ear. or pick your phone up by the "string ; Also the included material, like manual and stuff is...

Great headphones for the price


These are a great pair of headphones, well worth the price!

Great sound quality, microphone works great, has a button (ooohhh!). Very comfortable tips. Easier to clean than memory foam tips

Mic near useless on a moving bike

Good quality sound, not durable.


Purchased in November and use these daily on my walk to work, in the office and occasionally at the gym. The rubberized ends quickly cracked and split causing the wires that connect to the plug jack to become damaged. Less than a year old and they have...

It is good for my phone


I am not a expert on the earbuds. From my experience, this one is good for calling. Maybe it is not good enough to enjoy music. In all, I like this one.

Okay Headphones


These headphones are just okay. They sound decent but the one thing that bothers me as that you can't turn the volume up or down from the headphones
