I have been looking for an easy and cheap way to connect my Sony WH-1000MX2 Bluetooth wireless headphones to other devices that didn't have bluetooth connectivity. Saw an ad in GreenGuide from Radioparts for $24.99. Thinking that was cheap, but then looked on Ebay and found this Aus seller.
Just received mine today. Works fine and no lag for TV watching. Connected via Tvs Audio OUT RC cables. Just be aware if you have other devices connected to TV the sound wont come through. Ie I have put it in the Audio OUT of the DVD. Will just get another RC cable to enable me to switch between the TV and other device.
Tested 21m without line if sight.
My old laptop doens't work with Bluetooth, so using this to connect wirelessly as well.
Sound is ok. With the Sony's there's an app with an equalizer or set sound stages which works to allow adjustment of sound quality to headphones.
Can also be used as receiver. Connect it to a speaker RC points and play your phone music to the speaker. haven't trued that yet. Not really why I brought it, but could be helpful to others.
Anyway thought I would share. Sure there are cheaper, but you would be waiting for it to come from China and may not work. At least Aussie seller.
Note that it only comes in a light cardboard package around the unit. 3 cables and an instruction booklet. The free postage doesn't come with tracking. So advise you use PayPay for assurance if item doesn't arrive. Took about a week through slomo Aussie post. It was free postage.
A lot of eBay Seller have similar.
Better ask at forum.
