Słuchawki się nie łączą, cały czas wyskakuje błąd. ### 1/5 — Connexion impossible *2025-08-27, version 1.27.2* L’appareil en lui même semble de bonne facture et robuste. Le son est de bonne qualité aussi, malgré cela il diffuse des basses pour ma part trop étouffante, ce problème aurait sûrement pu être réglé grâce au personal sound, mais impossible de trouver l’appareil sur l’application. Ce soucis semble être récurent. ### 1/5 — Doesn’t connect *2025-08-24, version 1.27.2* İ cried because of this lovely app. What a sweet thing that it does NOT connect. Im only connected to my headphones and i’m even playing music but this freaking app cannot find somehow. AND my music keeps shutting even i dont move my head.

Jak zezwoliłem na łączenie z urządzeniami jakimiś przerzuciło mnie na ustawienia i wyświetlił się mały wykrzyknik w żółtym trójkącie, przestraszyłem się że to wirus więc szybko odinstalowałem. Słuchawki bardzo fajne ale aplikacji nie polecam. ### 1/5 — Nul *2025-08-10, version 1.27.2* Impossible de connecter mon casque ### 1/5 — Impossible de se connecter *2025-08-05, version 1.27.2* Application nulle ## Frequently asked questions about (Legacy) FnR Personal Sound ### What does the FnR Personal Sound app do?
