Attach it to transmit from my TV to my Bluetooth head phones and also to my games chair.2. Receive Bluetooth audio from my phone to play through the AUX socket in my car. Although my car has Bluetooth for calls, you cannot transmit audio (music) to it so this is perfect, saves having to connect it to the car with a cable and all the hassle that that bringsIn saying that, I'm sure I will end up using it on all sorts of other devices as well, such as my HiFi unitEasy to set up (although you may have to switch it to 'receive' so that it can find your phone. Just like any other Bluetooth device, you put it into pairing mode and away you go. The first time I turned it on, because it wasn't paired with any device it went into pairing mode automatically. once connected you get a constant blue light to show success.When fully charged, it says that you have about 10 hours transmission, which is fine for the car, I cant see any journey being longer than that. When it is connected to my TV, I can have it permanently charging from one of the USB outlets on it. You can use any Micro USB cable but it does come supplied with one though.It's smaller than I thought it would be which is a good thing, you can see the size of it in my hand.Just about the only thing you need to remember to do is switch to transmit or receive. This really has solved a lot of problems for me and I'm glad I bought it. ### ⭐⭐⭐ 3.0 out of 5 stars low latency in TX mode only *by A***N on Reviewed in the United Kingdom on 3 May 2017* Beware! this unit only offers low latency in Transmitter mode. At least that's what Acekool tell me and I suspect they are correct.Purchased two as a TX - RX pair. Units link up ok and sound pretty good but I measured 200ms latency which is useless for my application. Looking for a low latency RX to test this out now :-) ### ⭐⭐⭐⭐ 4.0 out of 5 stars High spec, low peice! *by M***N on Reviewed in the United Kingdom on 2 March 2017* Well designed generic alternative to mainstream products. A Feature packed item at a competitive price; does what it says in the description. Only "Con" is the translation of the user guide into English, but anyone familiar with Bluetooth devices should have no problem using it to its full potential. --- ## Why Shop on Desertcart? - πŸ›’ **Trusted by 1.3+ Million Shoppers** β€” Serving international shoppers since 2016 - 🌍 **Shop Globally** β€” Access 737+ million products across 21 categories - πŸ’° **No Hidden Fees** β€” All customs, duties, and taxes included in the price - πŸ”„ **15-Day Free Returns** β€” Hassle-free returns (30 days for PRO members) - πŸ”’ **Secure Payments** β€” Trusted payment options with buyer protection - ⭐ **TrustPilot Rated 4.5/5** β€” Based on 8,000+ happy customer reviews **Shop now:** [https://www.desertcart.pt/products/64624309-bluetooth-4-1-transmitter-and-receiver-acekool-2-in-1](https://www.desertcart.pt/products/64624309-bluetooth-4-1-transmitter-and-receiver-acekool-2-in-1) --- *Product available on Desertcart Portugal* *Store origin: PT* *Last updated: 2026-04-24*
