Reviews here said it won't fit in remodeling older bathrooms IT DOES FIT RETROFIT and anywhere you want to install it you just have to maneuver around the joists takes 30 min to install.
Noise level is amazingly low compared with the 110cfm suction power it provides, Bluetooth is really easy to pair just turn the vent switch on and scan the Bluetooth on your phone you will find it as "sensonic vent fan", sound quality and volume are really impressive considering only 2 small speakers are hidden inside the vent, it's lacking the bass but hey, what can we expect with such a small speakers the quality is already really nice to take a shower with it wasn't designed for sound pros listening to music in acoustic room with 20k surround system lol its just makes your bathroom time more musical 🎶 so all in all worth every dollar, easy to install (installed in a 60 yo condo without any issue) and sound is really awesome (you can hear it all over 2 bd condo with volume on 3/4 high).
Don't hesitate and get it if you want a great inexpensive vent with the very nice extra of the sound feature, if they added a LED light I would have given it 6 stars!
