### 1/5 — Doesnt work with wired dsp iems. Whats the point.

*2026-07-14*

Bad

### 1/5 — Doesn’t work with Bunny DSP

*2026-03-22*

Like other reviewers pointed out, this app doesn’t work with any of their wired DSP IEMs. Defeating the purpose of them altogether. Bummer. Will be returning my IEMs because of this.

### 1/5 — Can’t recognize type c

### 1/5 — Cannot recognize wired usb c iems

Title

### 1/5 — Useless

*2025-09-21, version 2.3.9*

This app is supposed to be able to control the EQ of the Tanchjim Bunny DSP IEMs but when I open it, it tells me to connect the device via Bluetooth but my IEMs don’t have Bluetooth meaning that getting the DSP version of the IEMs was pointless with iPhone. Fix this ASAP!

### 1/5 — Doesn’t recognize headphones

*2025-05-06*

My tanchjim one esp headphones work with the android tanchjim app but not this one. Worthless app and mid headphones at best.

官方客服告知 iOS 无法使用 App，安卓可以正常使用，这是不是区别对待？

### 2/5 — I cannot use the app

*2024-03-21, version 2.1.9*

I haven’t been able to use the app as it won’t let me input telephone code use my phone number. Why is this pls? Sort it out

### 5/5 — bug已修复

*2023-07-11*
