Excerpt: The sound quality on these are pretty good. I primarily use them for talking on the phone and haven't really used them for listening to music, but they've been working well for talking on the phone. They are also very lightweight and comfortable and do not fall out of my ear. I wouldn't say they're "flimsy" construction, but I've seen more expensive headsets with more solid construction.
Summary: These are good but not something you would expect from a brand name such as sennheiser I've already own another over the ear HD 202ii headphones but these sounds nothing like them..... But that not necessarily means that these are bad. Like I've said it's good but don't expect too much specially when you are a bass head like me.... But still the sound is good vocals are clear and trables are good only expect to be the bass a little punchy.....
Summary: Noise Cancellation is awesome and perfectly fits too. Very good product. Recommended for all OnePlus One users out their. I am using it with my Oneplus One and enjoying the Audio FX very much. Must buy.
Summary: Its good. Not Awesome. I own CX180 already and I was happy with the sound quality of it. I bought this just because it is having mic support with smartphones. Pros: Good Sound Quality as always from Senheiser, Mic recording is beautiful, extension given and the pouch is given good enough to carry in your bag/purse. Cons:Not a tangle free wire, While placing the earphone in the ear we need to hold it at the tip.
The headset is really good with regard to music playback

Summary: The headset is really good with regard to music playback.. The problem is the wires are too thin. The dual 3.5mm jack works well with all phones. The noice cancellation is too good. You literally cannot hear a vehicle horn or any other noice.
Simple Design.. Value for Money..bass go in tantrums at top volumes

Summary: The Sennheiser CX 275s is an earphone pair geared towards the bass lover on a modest budget. At Rs1550 (though i got it for Rs900 on big billion day sale), it's neither cheap nor over-priced, and offers solid, distortion-free audio performance. The boosted lows will scare away purists, and even bass fiends might find the highs, which are boosted and tweaked in peculiar spots, occasionally tinny or harsh.
