### ⭐⭐⭐⭐⭐ Sennheiester wired headphones
*by J***K on 11 April 2024*

These headphones are very well made and great sounding they come with several ear pods even for people with small ear Channels for you to choose from they are a little expensive but worth the money from Amazon ….

### ⭐⭐⭐⭐⭐ Good brand good sound good price
*by M***S on 11 March 2025*

Bought for my daughter who loves them. Replaced an older set of the same brand

### ⭐⭐⭐⭐ 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.
