Everything you ever wanted to know about this Jack!
I've used this devise to play songs to my older PA system from my phone. I put it through a test of about 4 hours tonight, I play drums along with the music. No problems it worked perfect. It was a very enjoyable session. I bought this one used. However it looks brand new and works great. For about 1/2 the price of a new one. Its designed hassle free just sinc to your phone and plug it into your PA system adjust your PA to your phones volume. It looks pretty durable and fits in a shirt pocket. The sound is really good. I think for my money I got a great deal. If something happens to this one, will buy another.

Works well with amplifier
I had hoped this would work in the car so my son could plug his phone into the old stereo. While it did, the sound quality was terrible. I know this isn't what this is designed for - just letting you know in case you had the same idea.
It does work great with his guitar amp though. He's able to easily play music from his phone through the amp and the sound quality is great.

A great bluetooth receiver for any gig
The 6.35 has been an excellent tool for me. It has allowed a great deal of versatility as well as a consistent and reliable connection. I've had no concern of dropped signal or pairing issues. I've provided a video that highlights some of the features as well as operation.

Niche product, but exactly what I was looking for (6.5mm + Bluetooth)
This is a really interesting Bluetooth receiver. I’ve researched a lot of these and this is the only one I could find that does Bluetooth with a 6.5mm jack, which is a very specific use case. It works as advertised for me and has been a handy little adapter when you need that exact setup.

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.
