I was prepared to be unimpressed by the Avantree Oasis TC-500, but I am actually pretty impressed. It is a very simple unit overall, but simple as in you don't have to guess how it works - it is very intuitive to use, and the voice prompts that pop up when you're configuring the unit are easy to follow and understand. Packaging on this and other Avantree units is excellent, and the encouragement that the packaging uses to prompt warranty registration indicates that Avantree cares about its products. I am configuring this unit to transmit the headphone output of a relatively small audio mixer (about ten stereo inputs) to a receiver unit about 50 feet away. If I run into issues when I test this at range I'll amend this review, but based on my close-range testing, I don't expect problems.
There are two forms of audio input or output - a 3.5mm headphone jack for analog audio, or an optical fibre cable input fore digital audio inputs. There is a throw switch of the unit to send it into transmit or receive mode, and an on/off switch to start Bluetooth operations or to bypass them for testing or using connectivity locally. A membrane control panel enables you to switch between aux (3.5mm analog) and optical inputs/output, and to re-start the Bluetooth pairing mode. It comes with a standard 3.5mm jack cable (on both ends), a 3.5mm to RCS stereo cable adapter, and a short optical cable.
You can use this in receive mode for any headset-level or component audio input, and you can transmit audio to any Bluetooth device that will pair with it. Note that this unit is enabled with AptX Bluetooth technology, which CAN enable low-latency audio, but the unit paired with this unit must support that capability also in order to get that feature to operate.
My own use is not that common, perhaps, but not too uncommon, also. The headphone-level output of the audio mixer goes to the Avantree Oasis in transmit mode, is paired for reception with an Avantree Roxa Plus Bluetooth receiver, and the analog output of the Roxa Plus goes from the 3.5mm jack output into a USB mic/headphone adapter (mic side), which is inserted into a Macbook Pro Retina. This enables remote recording of the mixer board's output in software running on the Macbook. In testing, the audio sounds GREAT, and i am excited to try this in a production mode soon.
There are cheaper units, but I can understand why this unit is highly rated and a bit more expensive - it feels "built to last," is very easy to use, looks like a pretty solid piece of equipment, and seems to have pretty good service. Their support line couldn't give recommendations on hooking up a Macbook, but this is a pretty arcane topic, so overall I was very pleased with the email support provided. Give it a try, my guess is that you'll be very pleased.

Great Sound , Cut out intermittently on first use but mostly working good now.
I purchased based on the Amazon reviews high rating. I just received this yesterday. Initial set-up was easy. Selected transmit powered it up, put my Bluetooth earbuds in pairing mode and it connected immediately.I connected optically to a new TCL TV. Sound is excellent. Initially range seemed awesome. Walked all over with no interruptions. After an hour or so though I started getting cut outs. Even just 5 feet from the transmitter. Then it worked well for awhile but then again occasional cutouts. At one point the unit rebooted itself and reconnected. I noticed many cutouts when my microwave was on. In a most recent use I had 3 hours with only one brief interruption in front of the unit and one when I walked out of view. I think living in an apartment building may cause the unit to be effected by neighbors appliances.I use Bluetooth 4.1 Earbuds. I have used the same earbuds with my cell phone and haven't had any problems. I will test a few more days before I decide whether to keep or send them back.* updated to 4 stars since I had mostly uninterrupted listening last night.* updated to 5 stars, been working perfectly. Not sure why I had trouble at first.* Update after 3 weeks - Occasionally sound cuts out but not often - Sometimes voice is out of sync, turning off and allowing headphones to reconnect seems to fix - Long range doesn't work well through walls and fixtures - All in all I'm pretty satisfied, I had more problems with my Roku that had an audio jack in the remote. You can easily turn off the annoying voice so I will give this unit 4 stars.Final Update - It's been working flawlessly 5 stars
