Koppelt von 20 Versuchen vielleicht 1 mal mit den Kopfhörern. Wenn man dann 1 min Pause einlegt mit dem Musik Hören, wird die Kopplung unterbrochen. ### 1/5 — Have never gotten app to work *2024-07-16, version 2.11.7* I really like the MTB 03 earbuds, but the app has never recognized the earbuds and thus I have never gotten it to work. Clearly the app is not well tested. A shame from a luxury company to have such lousy tech. ### 1/5 — Avoid *2024-06-02, version 2.11.6* Very disappointed. Clearly you purchase this because of the Montblanc name as it is associated with luxury. You don’t purchase this because they’re known for audio quality. The earphones won’t charge properly. It is not at all clear about troubleshooting. I could never get one of the earphones to play. They won’t reset to factory settings. They say to watch wether it blinks blue and white. Mine never changed from blinking green. Despite charging and recharging the case and the earphones, the app kept telling one or the other earphones was at 0%. This despite the fact that the left one never played, only the right one. Bottom line, a lot of money and a lot of trouble. ### 1/5 — Muy mala app *2024-05-02, version 2.11.6* Aplicación 0 funcional. ### 1/5 — No reconoce mis MB01 *2024-04-04, version 2.11.6* Por más que intento, vuelvo a descargar la app y demás; NO hay forma de que se conecten mis audífonos Montblanc_MB01 a la app. Por lo que no se puede entrar a los ajustes para personalizar el audio. Muy mal. ### 1/5 — 별로네 *2024-03-19, version 2.11.6* 최적화 미흡 한글화 미흡 그냥 모양만 흉내낸수준의 앱 다음에는 제대로 준비해서 만들거나 업데이트 해주길 ### 1/5 — Fix the app and update the firmware please *2024-03-11, version 2.11.6* Great product but the software doesn’t deliver its promise. Can’t save settings and once paired the known left earbud problem starts again. I’m using the airbuds without installing the app with no problem. Please fix the software issues asap. ### 1/5 — Will not stay connected *2024-02-24, version 2.11.6* I love the sound, look, and feel of the MTB 03s, but the constant disconnection just gets increasingly frustrating. My phone will be connected to the pods, but within the app it does not recognize them, which means I cannot adjust the EQ until I re-pair them in the app. This happens weekly. I also wish I could set a default EQ and ANC. I think the different EQ settings and even custom option are great, but having to go into the app to select my preferred setting every time I put them in is very annoying and not at all efficient. ### 1/5 — Não funciona *2024-02-06, version 2.11.6* O app não conclui o emparelhamento, você emparelha no iOS, consegue utilizar mas Com uma pessima qualidade, teoricamente o app ajustaria isso, mas não conclui o pareamento e não existe suporte para o App, já enviei e-mails solicitando um auxílio, pois custo a acreditar que a marca iria deixar o app “largado” dessa forma, mas para minha surpresa é ruim mesmo. Decepcionante, o Bose é absurdamente melhor ### 1/5 — Mala *2024-01-28, version 2.11.6* A cada instante se des configura el ecualizador de mis mb01… siendo unos audífonos tan caros debería de tener mejor aplicación. ### 1/5 — Problemas con iPhone *2024-01-20, version 2.11.6* Cuando estás en una llamada telefónica la corta, por favor arréglenlo porque pasa únicamente cuando usas el teléfono. ### 1/5 — 왼쪽 이어폰 인식 불가 *2024-01-18, version 2.11.6* 일주일에 한번씩 같은 증상 발생 매우 귀찮음 ### 1/5 — Pésima *2023-12-26, version 2.11.6* No es posible que una marca tan prestigiosa no pueda resolver el problema en esta App, simplemente no reconoce los MTB03 ## Most critical reviews (10 lowest-rated) ### 1/5 — Software issue *2025-12-03, version 2.15.1* Cannot pair app to earphones despite numerous attempts ### 1/5 — Absolute trash *2025-08-25, version 2.15.1* This app doesn’t work properly or acknowledge pairing at all. It will help you pair in a long painful process but not acknowledge it actually happened. It’s much better to use the settings on the phone. The buds themselves seem to be working just fine and the only reason I was trying to use the app was to see if there was a “find my” function like an iPod. Anyway I’m deleting this app it’s garbage. ### 1/5 — Connessione e pairing assolutamente poco pratico!!!😔 *2025-06-29, version 2.15.1* Incredibile, tutto il contrario di quello che uno vorrebbe dalla praticità di un auricolare a partire dalla fase di “pairing” e dal dover effettuare il download di una applicazione ad hoc, per non parlare del fatto che alla fine funziona un solo auricolare e l’altro neanche si ricarica, non da segni di vita! E tutto ciò dopo aver speso una cifra per l’acquisto! Esperienza assolutamente negativa 😱😔 ### 1/5 — Poor *2025-05-12, version 2.15.1* I purchased this product and already replaced it once due to it not working. Unfortunately, it has stopped working again and won't connect. This is an extremely poor-quality product ### 1/5 — ㅈ같은 어플 *2025-02-25, version 2.15.1* ㅈ같은 어플 관리 제대로 안해서 안씀 ### 1/5 — 아 빨리 고치라고 *2025-02-09, version 2.15.1* 애ㅅㄲ들 소꿉장난도 아니고 한 쪽만 들리고 가 ㅈㄹ이여 ### 1/5 — Calidad pésima *2024-12-27, version 2.11.7* No funcionan correctamente y no permite emparejar; una estafa ### 1/5 — Can’t use equalizer *2024-12-19, version 2.11.7* I was able to make it a personalised sound experience according to what I like when I firstbpaired my the earpods but now the app doesn’t show that option/the equaliser. Basically NO options!! Fix the damn thing so we can at least use it properly!! ### 1/5 — Does not work *2024-12-17, version 2.11.7* Useless app! Doesn’t recognize the headset. Doesn’t connect even store admitted the app is useless. ### 1/5 — No conecta *2024-11-05, version 2.11.7* No detecta los audífonos MB03… malísima la aplicación. A ## Most praised reviews (10 highest-rated) ### 5/5 — Great headphones and app *2025-04-04, version 2.15.1* Great headphones. I have the Apple AirPod, Max, top-of-the-line Sony, and top-of-the-line Bose. I have been dissatisfied with all of them. These are far superior and the sound quality, build quality, and app are phenomenal. ### 5/5 — Sincronización de audífonos *2025-02-03, version 2.15.1* Funciona muy bien para configurar todas las opciones de los audífonos ### 5/5 — Muy buena *2024-07-18, version 2.11.7* Excelente, a los que no les funciona es por no leer con detenimiento sus funciones ### 5/5 — Great *2022-06-03, version 1.0.3* Please add more EQ options ### 4/5 — Sí funciona 2025 *2025-04-10, version 2.15.1* Desconozco los problemas del pasado pero la app me ha funcionado bien en cuanto a la personalización de los audífonos, solo se congeló con el registro de mi cuente mimi de prueba de sonido. ### 4/5 — Good app good headphone *2025-01-25, version 2.15.1* It is so easy to pair headphone usually the process takes a lot of fiddling although I wish there was parametric eq ### 3/5 — 아직 버그는 남았지만 그래도 프리셋 이제 저장됨 *2023-08-07, version 2.11.1* 원래는 프리셋 초기화되고 개열받았았는데 개선됨 대신 페어링 그지같이 안되고 펌웨업데이트 진행해도 안바뀜 ㅋㅋ ### 3/5 — 이퀄라이저 자꾸 멋대로 바뀜 *2021-05-17, version 1.0.3* 제목 그대로 ### 2/5 — Very disappointed *2024-02-29, version 2.11.6* Same problem about connections , changed in store and happen. again with new headphones will not recommend this headphones to any body ### 2/5 — 펌웨어 업데이트 문제 *2023-07-18, version 2.11.1* 펌웨어 업데이트를 해도 다시 펌웨어 업데이트를 하라는 메시지가 반복해서 뜹니다. --- *Data collected daily from the US App Store and indexed by [AppsHunter](https://appshunter.io/).
