Bluetooth 5.4 Module Kit

This little set-up meant I didn't have to replace my whole sleep mask and saved me about 50%. The original sound unit was micro USB and the tiny tongue piece broke off and became unchargeable. This one is USB-C, so it's compatible with all our cords and that won't happen again. It was a bit snug getting it into the mask, but once in, there wasn't a single glitch. If I run into any issues I'll update my review.

My sleep mask isn’t a Musicozy brand it fits and works perfectly.

Used this to replace the module in my older musicozy mask. The sound is better, but I'm taking a star off due to no charging cable being included. There is a usb micro port on top of the module for charging.

Although a bit tricky to replace in the facemask, this is a great, affordable option when the unit stops working. No complaints about the unit. I usually break the cord by accidentally pulling on the mask when it is plugged in.

When the device works, it is a helpful product. I like falling asleep to sound connected to my phone. But I ordered this as a replacement for the first module that came with mask, and now the replacement has a broken charging wire and won't recharge. The quality of the cords is low, they breaks easily and must be replaced annually.

30 days return and mine are giving out after only about 45......

This was a replacement for the first o e that came with the mask. A tip to extand the life, as the wires are rather thin, is to sow the charging portion of the unit in place. This stops it from flexing the wire too much and eventually breaking like thenlast one did.

I use sleep headphones every night, and this brand is sturdier with better sound quality than other brands I’ve tried.
