Review: Great earphones - Bought these as a gift for someone predominantly using them for gaming - says they are much better than other purpose built gaming earbuds and headsets they have used previously. I looked around for a while at a decent pair of wired earbuds and settled on these as well priced, not breaking the bank, and having decent standards. Would buy again - they aren't going to be the best earbuds in the world for any audiophiles but for most purposes they are a great option.
Review: greaat earbus / headphones - great headphones for the money.. ive had a couple of these now over a few years highly recommended

## Questions & Answers

**Q: Does it have a microphone and how good is it?**
A: Works well on my phone and PC for taking calls at least.

**Q: One customer claims it has volume control. Unless I'm missing something, it does not have remote volume control.**
A: It does not have volume control per se, but it can be configured.  There are +/- buttons on the part of the cord where the mike is.  The default on an iphone is those buttons skip the song forward and back.  In settings/control center, you can redefine these buttons to use as volume control.  I suspect that android operating systems have something similar.

**Q: Do these have same length left and right cables**
A: Yes. The cables are the same size.

**Q: Can I get an answer on exactly how long the cord is?**
A: 1.2 meters that's from sennheisers website

### ⭐⭐⭐⭐⭐ Great earphones
*by C***A on 29 July 2023*

Bought these as a gift for someone predominantly using them for gaming - says they are much better than other purpose built gaming earbuds and headsets they have used previously.

### ⭐⭐⭐⭐⭐ greaat earbus / headphones
*by M***. on 16 July 2025*

great headphones for the money.. ive had a couple of these now over a few years highly recommended

### ⭐⭐⭐⭐ Need to be tweaked if you listen to electric guitar based music
*by R***S on 2 April 2024*

These headphones are good, but you are going to need to make some adjustments on your equaliser for them to sound correct if you listen to guitar based music. The bass and high end are turned up too much so the mid range is lost. They feel like they've been designed out of the box for dance music. It's a fairly simple fix. Just slightly boost the mid ranges on your equaliser and slightly turn down the bass and high frequency and it will get tracks sounding as they are supposed to.
