## Customer Reviews

### ⭐⭐⭐⭐⭐ Magnificent sound
*by H***Y on August 13, 2024*

I replaced the stock Sennheiser 800s headphone cable with this unit. Observations:-The contstruction quality is obviously an improvement- The overall sensitivity of the headphones are up a significant degree (5db)- The music details seem improved as does extension.A very worthwhile investment

### ⭐⭐⭐⭐⭐ Skeptical at first
*by N***T on June 18, 2020*

I had to get these as a replacement as the HD820's I bought had the XLR balanced cable yoinked, I almost had a heart attack seeing the LOWEST priced replacement cable from a third party were these. As the title states I was skeptical, but then I swapped out the cables, and my god, this cable really livens up your music, it's hard to explain it but I'm sold on expensive third-party cables being cable of giving you better sound.

### ⭐⭐⭐⭐⭐ Thin but sturdy
*by D***N on March 10, 2021*

Feels great! Very nice cable. Not too thick or cumbersome.
