### 1/5 — Неверный язык

*2026-08-14*

При выборе русского языка в настройках жестов язык не русский

### 3/5 — Нет возможности  зарегистрироваться.    没有注册选项。There is no possibility to register.

*2026-08-07*

尊敬的开发者，请解决注册问题。当我输入邮箱地址和密码时，注册过程就卡住了，因为屏幕布局导致我无法点击“下一步”或“注册”按钮。所有内容都集中在屏幕底部，而且屏幕本身无法向下滚动。谢谢！

Dear Developer, please resolve the registration issue. The registration process gets stuck when I enter my email address and password because the screen layout prevents me from clicking the "Next" or "Register" buttons. All content is concentrated at the bottom of the screen, and the screen itself cannot scroll down. Thank you!

### 1/5 — Configurações de equalização

*2026-07-27*

As configurações de equalização não ficam salvas no fone, e resetam constantemente, mesmo sem desligar. Tenho o Haylou S40.

### 1/5 — What a disappointment

*2026-07-19*

They have an app but it’s only for the better models and it does not have all of the cheaper models. If you have an app then have all your earbuds in it.

### 2/5 — Pouco prático e ultrapassado

*2026-07-12*

Preciso sistematicamente remover os fones (os dois), guardar na case, abrir, remover ambos para reconectar. Não está emparelhando, mas conecta via Bluetooth 🤷🏾‍♂️

### 3/5 — Уныло

*2026-07-01*

Не могу зарегестрироваться в приложении

### 3/5 — Useful App!

*2026-05-30*

The app has some of the most simple features but it works fine you have to connect again every time you open the app and it takes time btw i liked it i have X1 2023 airpods ✨

### 2/5 — Крутые цели за свою цену

*2026-05-18*

Наушники мне нравятся, за свою цену работают идеально. 
НО приложение стоит дорабатывать: 

1. Не сохраняются настройки звука. Пример, ставлю «Тяжелый Бас», отключаюсь от наушников, на следующее утро при подключении нужно опять заходить в приложение и выставлять Звук -> «Тяжелый Бас»

2. При подключении к наушникам, а после подключении в приложении, Bluetooth считает, что подключилось еще одно устройство. 

После чего положив телефон в карман начинает пропадать/залипать звук. Достаю из кармана все звучит хорошо. 
После отключения и повторного переподключения все работает корректно

### 1/5 — Загадочная регистрация

*2026-05-15*

Как зарегистрироваться?

### 3/5 — Funcional mas incompleto

*2026-05-09*

A haylou parece ter desenvolveu esse app porcamente, basicamente me serviu para ativar a conexão multiponto e mudar o nome do meu fone de ouvido, funções que não se destacam perante a concorrem
