1Mii B03Pro+ Bluetooth Transmitter Receiver Certified LDAC for TV Home Stereo, Long Range Wireless Audio Adapter with Screen, Optical RCA AUX 3.5mm Outputs/Inputs

I bought this device to connect my hifi system to my sound bar it works perfectly and although my sound bar doesn’t use the higher order Bluetooth connection it is quite satisfactory I could get a Bluetooth receiver that supports the better protocols but I am happy enough with the system as is.

I wanted an Analogue Line to LDAC transmitter, this came up in searches.This was to allow the use of Sony 1000 XM4 headphones with the home turntable setup with analogue line out.Its 100% worth it, I've not experienced the drop and raise in volume which others have (don't know their use case), the Bluetooth range is simply phenomenal with my usual connections for phones-headphones only making it round one corner in the house; whereas this got me a solid connection all over the house and even to the bottom of the garden with only a loss in quality (LDAC) rather than full drop outs.I have not used it as a receiver and don't plan to.Its a petite device, easy to hide in your setup, only mild irritant is USB power and needing another block.

I wanted a Bluetooth transmitter to allow me to listen to the radio/tv/computer etc output on my Yamaha amp using noise cancelling earbuds.The 1Mii B03Pro+ came well packaged and with all the leads - no plug with usb power supplied, due to differing country standards, no doubt .I plugged the phono to 3.5mmm lead into the line level output at the back of my Amp and into the 3.5mm input of the B03Pro. Switched to TX and then connected the USB c power lead. Both my freebuds pro 3 and then the liberty 4 nc buds paired within seconds. The unit will now automatically link with whichever buds i put it my ears. The range is very good. I am very pleased.

All seemed perfect at the setup phase but then when we started watching a movie the volume would dim for a few seconds and then go back up, at random intervals, on different sources, re-plug the old Avantree and problem gone.Very frustrating that this item did 99% of the job right but then was plagued by such an odd problem…the quest for a great BT transmitter continues…

Only used as a TX device for bluetooth headphones and as a kind of mini hub. Aux (analogue) was great, and pairing, connection, LDAC, transmission range, etc were very good too, but the optical input just didn't work. Tried multiple devices... nothing happening. That's a basic functionality for this thing. I might try another one, but reading other reviews, it seems like the QC isn't so good. The search for a reliable bluetooth transmitter continues. Geez.

The B03pro+ seems well designed and constructed. My use of it was for listening to music transmitted from my hifi amplifer to my Sony WF 1000m4 earbuds: my hearing of higher frequencies has deteriorated and these sensational earbuds improve my listening experience dramatically. Unfortunately, this set up did not work for me - low volume, limited sound quality, latency. Maybe for the TV use as intended it works very well: I did not try this and returned the device. The statement that this device could assist where someone in the family with hearing impairment could use this while others listened at normal levels without it is, I submit, somewhat misleading. The latency means there is a kind of phasing effect between the sound from the device through earbuds and the ambient noise from the basic system. Not for me.

No volume also part miss
