The sentence that prevents a return
“This product is ONLY a Bluetooth receiver, not a transmitter.”
Receivers and transmitters look the same, sit in the same category and do opposite jobs. A receiver takes Bluetooth from a phone and feeds an amplifier; a transmitter takes analogue from a television and feeds headphones. Buying the wrong direction is the commonest mistake on this whole shelf, and this listing forecloses it in its own note.
The range, stated honestly and with a condition
10 to 12 metres indoors, without obstacles. Most listings quote an outdoor line-of-sight figure that nobody experiences. This one gives an indoor number — and attaches the condition that makes it optimistic, since indoors generally means obstacles.
The power
No battery. Mains adapter or USB cable, stated. That makes it a fixed installation, and the maker says so rather than letting a buyer expect portability.
What is missing
The codec list. Nothing named at all. It will connect to anything over SBC; beyond that, unknown.
Where it sits on this shelf
The clearest listing here and the plainest product. Nothing distinguishes it technically, and its honesty about direction, power and range is worth something on a shelf where those three cause most of the disappointment.
