### 5/5 — Awesome

*2026-08-09, version 4.8.3*

This is a versatile app that is a dynamite equalizer for my iPhone. There are preset configurations for several genres and you can create your own to match your  speakers or earphones. The only downside is how long it takes to load the music. A bargain at $10/yr.

### 5/5 — GOOD AP, BUT...

*2026-08-05, version 4.8.3*

....Many Apple songs have a DMT lock so you cannot equalize them. It is not the apps fault, it's some legal copy right issue. So out of my entire song library of 500songs I can only tweak like 20. Sorry if I missed it but, I wish it would just say that right on the first page. I don't have the knowledge or resources necessary to unlock the DMT. VERY FUN and EASY TO USE THOUGH. My earbuds are $7 so I wasn't expecting a miracle. I'm after earth shattering bass bustin out of my buds while I walk down the street....met but didn't exceed my expectations, with better quality buds you'd probably be golden and not need anything.

### 1/5 — .

Pour utiliser l'égaliseur, assurez-vous que l'application est autorisée à accéder à vos fichiers multimédias et à Apple Music. Ensuite, lancez la lecture d'un morceau depuis votre bibliothèque, appuyez sur le titre en cours de lecture, et les options « Amplification des basses » et « Égaliseur » apparaîtront au centre de l'écran.
