Sennheiser CX 275s had launched the Sennheiser CX 275s sometime back, and the headphone featured in-ear headsets, and microphone. The CX 275s are wired headphones, that come with 121 dB/mW Sensitivity at 1kHz, and 16 ohm headset impedance. Made for bass lovers, the headphones have a neat professional look in them. Priced in India at Rs. 2540, the CX 275s are neither too cheap nor too expensive, on the contrary they are priced just right. The no-nonsense and straightforward design of the CX 275s is one thing that we like, overall, the earphones are worth some space in your wardrobe.

Box Pack

Box Pack

The Sennheiser CX 275s come in a very basic box pack, that is made completely of plastic and paper. Opening the box is a bit difficult, but overall, the box has been designed well. The front side of the yells that the CX 275s block outside sound, and that the earphones are built for smartphones. On the back of the box the major features of the CX 275s are listed in a variety of languages.

The box packs the earphones, three different sets of ear adaptors to suit one’s need, a carrying pouch, and a cable to connect the CX 275s to the mobiles having different TRRS arrangement. You’ll be needing this cable to connect the CX 275s to devices like the Sony Ericsson range.

The extra cable to connect the Sennheiser CX 275s to devices with different TRRS arrangement came as a pleasant surprise. I have seen many of users with old handsets complain about this problem, but with this extra cable, you won’t have an issue.

Build and Overall Design

Build Quality

The no-nonsense attitude of the design of Sennheiser products has always appealed to me. I don’t like fancy headphones that have various colours just for the sake of having them, and various designs and patterns just for the sake of a “good design”. And for me, the straightforward design of the CX 275s was nothing short of perfect. Unlike other headphones that have a fancy cable, but normal ear-plugs, that Sennheiser CX 275s features a neat design of the ear-plugs that helps in putting them on to your ears and increasing friction(if you are a science student!).

Although the left and right signs on the ear-plugs are very difficult to find(they are on the inner sides of the CX 275’s cables, if you are still searching for them), but Sennheiser has smartly placed a raised dot on the left ear-plug, so you can use that to tell which one is which even in dark or when the lights are out.

The cable of the CX 275s doesn’t feature the same flat look as that of Tylt Tunz, but still, it is strong enough to bear jerks. The cable has an outer plastic cover that is soft, and feels pleasant to hold. The microphone and call end button is found along the left cable, and it is at an appropriate distance from the mouth.

The 3 sizes of the ear adaptors will basically be perfect for each one of you, unless you are an alien from Mars, or a giant from some fairy tale(no offence if they don’t fit you!). The tips of the ear-adaptors were perfectly soft, and felt extremely comfortable on the ear.

The Sennheiser CX 275s come with a neat look, but they are prone to tangle when kept in some tight space. But the wires are so flexible, that you could probably wind them up anyway.

Sound Quality

CX 275s Headphones

Having mentioned clearly on the box of the Sennheiser CX 275s, and on the official product page, it’s not a big surprise to find the sound quality of the CX 275s to be bass focused. The songs with mid-bass work extremely well, but I found the CX 275s to stagger a bit with high-bass notes and vocals. If you are a casual music fan, and just want to hear the regular songs then you would find the Sennheiser CX 275s’s sound to be perfect, but if you are a professional, then then they might not appeal to you.

The bass plays an integral part in music, but the CX 275s do lose their rhythm when songs with light vocals are played on them. Probably my ears are not working as great as they used to, but Arjit Singh’s vocals definitely sound better on my other pair of headsets than in the CX 275s.

On the positive note, the sound was very rich in detail, and I could differentiate between the different instruments being played very easily. If rock music, and music with mid and normal bass notes appeal to you then the CX 275s will do a great job for you.

As a mid budget headset, the CX 275s do great in sound quality, and if you want to satisfy the love for bass in your ears, that go grab the Sennheiser CX 275s.

As for the microphone, the mic does fairly well for calls, and some normal recording. If you aren’t thinking of recording some high tech. music with the microphone of the CX 275s, then you’ll be happy with the performance of the microphone. While having the earphones on the ears, the mic was at a distance of around 2-3 centi-metre from my mouth, and at this distance, the person at the other end of the call, was able to hear me easily without any issue.

Final Take

For Rs. 2540 ($69.95 in the US), the Sennheiser CX 275s are a good set of headphones for someone who is looking for a complete headset to accompany his smartphone. With microphone functionality, and a adaptor to connect it to old devices that have a different type of TRRS arrangement, the CX 275s has all the basic functions that most of us would want. Although the sound quality is a bit biased towards mid-bass, still, if you are a casual music lover, who would love to get his hands on a headset having all the basic features then the CX 275s is perfect for you.

    I love the sound quality of sennheiser earphones. Some smartphones incorporate sennheiser as their speakers in their phones. I just forgot the brand name but it’s locally available here in our country.
