A Brilliant Wireless Upgrade for My Audio Setup
This Music Receiver has been an excellent addition to my audio gear. I initially grabbed it to reduce cable clutter on a powered speaker setup, and it has performed far better than expected. The ¼" TRS plug makes it incredibly convenient for mixers, PA systems, and DJ desks—no adapters required, just plug in and go.
Pairing is fast and stable, and the aptX HD & Low Latency support really does make a difference. There’s no noticeable lag, and the audio quality remains crisp and full, even at higher volumes. I’ve streamed music and backing tracks from both my phone and tablet, and everything has synced perfectly without dropouts.
The 10-hour battery life is generous for rehearsals or small gigs, and I love that it charges via USB-C—no hunting around for obscure cables. The built-in DAC is another unexpected bonus, adding clarity and depth to the sound rather than compressing it like cheaper receivers tend to do.
If you’re tired of cables draped everywhere or want a clean, wireless solution for speakers or a mixing desk, this little device is a game-changer. Compact, reliable, and great audio performance—highly recommended for musicians, DJs, and anyone wanting a seamless wireless setup.

Fantastic Bluetooth Mono receiver
Sound quality of this Bluetooth receiver is great, I currently used this with an amplifier and it works awesome, i'm not sure how low latency this dongle is in ms but you can watch a movie without lips falling out of sync if for whatever reason you would want to use this with an amplifier for that niche reason. Build quality is also superb and very sturdy doesn't feel like it's just going to snap in your hands and the USB C is a nice added touch whereas a lot of technology like these dongles still use crappy micro USB for whatever reason.. When buying this make sure you do know that it will play music Mono also NOT stereo as you will need 2 of these dongles for stereo. Extremely handy dongle non the less considering there is no need for added cables which can be a trip hazard depending how high up you're plugging into.

Before you ask.
Can I make my guitar amp Bluetooth?
Yes — the 6dot35 plugs straight into a 1/4" input, so any guitar amp, bass amp or PA speaker becomes a Bluetooth speaker for streaming music or backing tracks at line level.
Bluetooth receiver with 6.35mm jack?
The blafili 6dot35 is exactly that: a 1/4" TRS (6.35mm) Bluetooth 5.1 music receiver with aptX HD, TWS stereo pairing and a 10-hour rechargeable battery.
