Sennheiser CX 275s sound quality experience

Sennheiser has been working in the sound profession for over 65 years and the experience of this speaks for itself. The Sennheiser CX 275s consist of high powered dynamic speaker system for great bass-driven stereo sound.

The range of frequency response is 17 Hz to 23,000 HZ. Let me elaborate for you. lowest frequency 17 HZ stands for bass and highest frequency 23,000 HZ stands for treble. Mostly song made up in this range.

Music audio quality is satisfied. Apart from this gaming is rising in other hands. I personally played PUBG Mobile on a daily basis. Well, I do play kinda strategically and for the win. In battle royale game like PUBG Mobile Sound-play king role to know where the enemy is exactly in building or taking TPP.

When I had CX-180 I played on Samsung j7-duo and I was always able to locate enemy location perfect when fight going inside the area of the building. you can identify if enemy prone above or below you.

Sennheiser CX 275s is so calibrated for sound output. Now, these days I am playing on Asus zenfone max pro m2 but upgrade soon. Let me know through comments on which device you used for playing PUBG Mobile.


Like other brands, this earphone also has 2 extra pairs of earbuds with the size of small and large because the medium size is also placed on the earphones.

Sennheiser keeps comfort at its best. It feels like you put cotton inside your ear in cold. So lite and sleek design to give you lighter and excellent experience on-ear.


The option missing in previous Sennheiser CX-180. This has call mic support. The button work as a play or pause song. Also as a call receiving and after that, you can cut the call as well.

Mic quality is good. an opposite person can hear you clearly. So good work on the mic in Sennheiser CX 275s.


I love this company about durability. here that I wanted to share an incident that happens to my sister.

I gave my Sennheiser CX 180 to my sister. when she is reaching back home the wire of earphone stuck around knee and audio jack instantly pull out from the phone. but the quality of sound remains the same. Wire not even single stitched.

So you wondering what about Sennheiser CX 275s. Well, the same incident happens to me as well when I was traveling to my college in the city bus. the wire quality is so strong.

The earplug is so strong that if you sleepover by chance your back gets hurt but buds not affected at all. super strong design by Sennheiser.


Well, this is a good reason instead of having other jack to increase the length of earphone wire.

Inside the box of Sennheiser CX 275s, they provide a 3.5 mm jack little extension cable as well in-case if your device required that. Well, the modern device doesn’t need that. I have tried this earphone on the following devices.

  • Asus Zenfone Max Pro M2
  • Samsung J7-Duo
  • Samsung J7-2016
  • Redmi Note 4
  • Realme 3 Pro


Inside the box of Sennheiser CX 275s, you will get one pouch to put your earphones safe. Well instead of having circular big pouch this small is good and great enough which fits in your pants as well.

While I was using Sennheiser CX 180 I had no idea that the company gives this kind of service. The brand has 4 service centers in all over India.

The fun part is you dont have to visit the service center yourself. If your earphone or any other Sennheiser products get damaged here’s how you can replace them.

  • Write the issue on paper
