Yeah, I have a few of those in the parts bin. 
Oh yeah, total POS. The only thing that worked was the LED, which actually bothered to change color. None of the computers even recognized it, and even on a cell charger, never even tried to pair.

Bought this one, $10, free shipping from Pennsylvania.
i bought one a few weeks ago and never got it to pair with anything i had or even another guys phone
The PSR-500 has some DC, so a DC block or ground loop isolator should help.I had a blutooth gadget that I used on my handhelds in the car. For a very short while. The pop it made when the squelch closed was too much. Way way louder than the audio was, so I gave up. I tried a couple of other ones, and they did the same thing. I was using a GRE PSR-500 and the RS clones. Only handheld scanners I have now. The ham HTs I have don't need to have any help with the audio.
Has anyone purchased one of these inexpensive Bluetooth receivers that has a wired output strong enough to supply line-level audio to their home stereo amplifier/receiver? Looking for something that won't require having to crank the home amp/receiver volume knob up abnormally high and with good enough fidelity to pass stereo streaming music from my cell phone via Bluetooth without breaking the bank. Thanks!
I use this to stream music from my phone, iPad to my stereo receiver. Works great.
