### ⭐⭐⭐⭐ Better than original factory for SENA
*by S***F on 27 December 2024*

Better than original factory for SENA More clear sound

### ⭐⭐⭐⭐⭐ Veel beter dan standaard
*by J***Y on 1 January 2025*

Zeer goede update ten opzichte van men origenele sena oortjes. Hoor nu de intercom goed door het geluid van de motor

### ⭐⭐⭐⭐⭐ Eigentlich wollte ich nur etwas lauter
*by D***L on 26 February 2026*

Ich hatte die normalen Lautsprecher in meinem Sena 30k verbaut und war mit der Lautstärke selbst voll aufgedreht nie ganz zufrieden. Also habe ich mich den Empfehlungen hingegeben und die HD Lautsprecher von Sena bestellt. In der App kurz umgestellt und ...... wesentlich lauter als zuvor. Ich höre während der Fahr nur noch auf maximal. 50-60% der möglichen Lautstärke und auch der Klang ist um längen besser. Schwer zu beschreiben, aber für den preis ein wirklich nützliches Upgrade
