Because of the low price, I didn't expect much, but I was actually very surprised how nice this unit is. It's made fairly well, has RCA as well as Mini Jack output and the AptX codec works great. Net, net - it's simply a GREAT device for the money. Better than I expected.

I typically have used Apple Airplay from an iPhone ( or DLNA from an Android) Wifi Devices to stream my music from my phones, but that comes at a cost. Sure, it's High Resolution to use Airplay or DLNA, but you need a WiFi Network and you need the Apps to CAST to the DLNA or Airplay device. iOS has this built in with Airplay but Droid is a bit more tricky with DLNA. And if the network is unreliable, or the receiver is too far from the Router, you may have issues.

With Bluetooth, it's simple. You go peer to peer. The phone Bluetooths to the Receiver and you are done. The range is not as far as a WiFi Casting network, but the advantages are simplicity and the ability to cast everything since it's Bluetooth OUT rather than a DLNA or Airplay Network.

All this background to set up saying;
I'm glad I no longer have to rely upon a WiFi network to stream high resolution music from my phones to my stereo devices. This little device works great, holds Bluetooth well enough and because it's true AptX, you get HIGH RESOLUTION LOSSLESS casting of your music. That is... PROVIDED your PHONE can stream AptX. This device is backward compatible, so if you have an older phone with Bluetooth 3.0 or even 2.0, it will still work. You just won't get high resolution music streaming. AptX is a lossless codec for Bluetooth and delivers high resolution via Bluetooth casting. For this price, you can't beat it. I have a few AptX receivers that cost 3 times as much and I don't see them as any better quality. This little device is great. If you have a receiver that doesn't have bluetooth built into it, this thing is great. I attached this to two of my older receivers and now I can play music from my phone to the pool area and inside the house on the main system that accompanies the home theater area. I used the RCA ports for the CD/DVD player inputs and the sound is great. Now I can broadcast all my favorite toons via my cell phone to the house, or outside near the pool. Small, but powerful, I like it.
Pros:
1. Easy to pair with NFC.
2. Nice auto connect
3. Simple USB power
4. Easy installation
5. Nice sound
Great product audio in for l/r stereo audio out to non Bluetooth devices and has a Mic for phone calls....if you want to pair an iPhone and a kindle to this it Will tell you device already paired simply turn. Off Bluetooth on the first device to be able to pair a second only 1 Bluetooth device in use at a time...in order to pair a device press and hold play/pause also the on off button and you're paired for non near field communication devices.

Love this product! The audio reproduction through the optical output is far superior to other Bluetooth receivers I've owned. It's a good option to have both optical and digital outputs. Sounds great through my Onkyo 5.1 receiver

I purchased this 2-in-1 adapter for primary use in my truck, which has a HandsFree Bluetooth, but my premium sound system does not receive Bluetooth for audio input.  The quality is very good, and this unit is extremely compact.  The battery stays charged for several hours.  (Other comparable units require a 5v connection to power all the time.)  I have a new Moto Maxx Android phone.  I get the best of both Bluetooth connections, where I can use the HandsFree for phone calls and the 2-in-1 to stream Slacker/Pandora audio...both at the same time.  It's great to be connected without the dangling wires!  I have not tried the transmit mode yet, but based on the ease of setup for receiver mode, I assume it would work fine.

Works perfectly with a Hobbypower NGFF adapter to provide Wi-Fi, Bluetooth, AirDrop, Handoff, and Continuity to my Hackintosh

Great device for adding bluetooth capabilities to your existing sound system. It was easy to set up -- just plug it in to your receiver. The bluetooth receiver pairs easily with your phone, letting you play anything from your phone through your sound system. It does require a dedicated wall plug as there is no battery/charging capability.

Works as expected with most apps via bluetooth. No issue to date (using Android )

The TX-8140 preformed nicely. I enjoyed the receiver's features, however the Bluetooth was spotty. I encountered Bluetooth connection issues.

Works great with any of the new smartphone bluetooth sports apps!

Super fast shipping. Was barely getting 15 ft. with a 4th generation ipod touch. Seller sent me a new Bluetooth 3.0 Receiver, and asked that I send back the Bluetooth 2.1 Receiver after I tested both. The new BT 3.0 Receiver is fantastic. I have no complaints whatsoever.

Worked out of the box with Raspberry Pi 2 running OSMC 15.11. Just needed to enable Bluetooth in the OSMC "Networking" GUI.

Currently using it with a bluetooth keyboard, have it paired using A2DP to an LG HBS730 and a Phiaton BT100NC

Range is about what I would expect, 8-15m before the A2DP starts breaking up.

I was trying to get this thing to run on Fedora 14 (2.6.35.14-106.fc14.i686. PAE) .. Not quite plug and play. Fedora saw the device under lsusb but not as a bluetooth device.

The fix?

Create /etc/modprobe.d/medialink-btusb.conf

and drop this line in it:

install usb:v0A5Cp21E8d*dc*dsc*dp*ic*isc*ip* /sbin/modprobe btusb; echo 0a5c 21e8 > /sys/bus/usb/drivers/btusb/new_id

Remove the dongle and reinsert into your USB port. Should be recognized after that.

Works well. Wired one to an incompentet Bluetooth receiver (TT-BA09) and a Bluefruit Feather M0 so I could power on the receiver programmatically.
