A couple of years ago, I got a Bluetooth transmitter and receiver unit from another brand here on Amazon. They were so finicky, when they did work. Most of the time they didn't. I had to face them directly at each other across the room. They cut out, they were staticy and most of the time they just failed. This soured me on Bluetooth for home music. I left a one-star review, and threw them in the garbage. More money down the drain for failed products.I've got this great Pioneer amplifier that's hooked up to a nice Klipsch 5.1 system, and a couple more big old Fisher speakers for the rear. I ha

I frequently watch TV after my wife goes to bed. In order not to disturb the peace I use headphones, but I’m tired of tripping over headphone cables.My A/V receiver has a Bluetooth receiving function built in, but it cannot transmit a Bluetooth signal in order for me to listen to the audio from an input source on Bluetooth headphones.I tried several lower-priced Bluetooth transmitters with limited success before I found a Wirecutter review that gave its highest rating to the 1Mii B03 transmitter/receiver.I read the negative reviews on Amazon and found several of the poor ratings seemed to be b
I bought this unit to connect to a bluetooth receiver upstairs, and to another room unit several rooms away. The unit connected flawlessly and with minimal effort. The sound quality is quite good, and the latency in LL mode is almost undetectable (very good).One item to be aware of: If you're using this as a transmitter to 2 bluetooth receivers, and you want to use the LL (low latency) codec, BOTH bluetooth receivers must support the LL codec. If one of your bluetooth receivers doesn't support LL, then the transmitter will automatically switch to the codec that lowest-common-denominator receiv
Have had this device about 4 weeks and, well, it just works.I initially bought a similar device in December 2024 here on Amazon (a techie friend said looks like this ought to do what you want so ordered it). It was always a bit wonky but figured I could live with it (would usually connect (after pairing the day before) with one or two sets of headphones; with others would have to re-pair). Then turning on certain headsets would cause the one that was working to drop. Was often a crap shoot what I might have to do to get two headsets at a time to work. I could usually get hers and mine to be ru
I really wanted this too work. It had just over 50% good reviews and that's good for any product so I was hopeful.The product itself was small, compact, and good looking. It really looked good on the shelf and unfortunately that's were the positive experience ends.Installation for me was a pain in the butt, this was in no part the products fault. I had to get behind a 65 inch TV that was snug in its enclosure. ( see picture)The instructions are definitely point and click, absolutely nothing difficult. Once install was complete (I used optical cables) the product did its initial setup for pairi
For a little background, I only used this for music so I can't speak to passthrough or latency. Second, I am using two of these, connected to each other. So I have a record player and a sound system that are unfortunately in separate rooms. I decided that I wanted the record player to connect to the sound system so I bought two of these. I tested the receiver with my phone and it has great sound from that. I like that it tells you how it's connected so you know what latency to expect. Now when I went to pair both of them together I was worried that it would be hard but it's as easy as putting
Pros:* The triple transmitter/receiver/bypass modes combined with optical and 1/8" audio jacks provide great flexibility for connecting this unit to computers and audio components.* Buttons and switches are nice; overall the box looks good and is easy to operate.To refute other reviewers:* It pairs fine with bluetooth headphones and speakers.* There are no noticeable audio quality issues in the transmitted signal. Users experiencing noise or static should read up on ground loops and experiment with power outlets their device and/or speakers are plugged into as well as with the placement of aud
I've got a Presonus mixer with a built in Bluetooth receiver that I use to feed a couple studio monitors. This works well when I connect my Android, but when connecting my Macbook Pro I have serious Bluetooth connectivity issues to the point where I'm limited to about 10 feet, and even walking between the Macbook and mixer will 'stutter' the audio and sometimes even drop the connection.I decided to try the 1Mii B03, and I have to say I'm extremely pleased with the results. I've connected the B03 in RX mode and can walk across the house (around 50 feet without line-of-site) with my Macbook and
