Review: greaat earbus / headphones - great headphones for the money.. ive had a couple of these now over a few years highly recommended
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.

### ⭐⭐⭐⭐⭐ 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. 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.

### ⭐⭐⭐⭐ 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.
