Bluetooth 5.3 Transmitter Receiver for TV to Wireless Headphones, Dual Link aptX Adaptive/Low Latency/HD Audio, Aux Bluetooth Audio Receiver Adapter for Home Stereo, Airplane, Boat, Gym

It's really mini. Smaller than what I expected. I like the size. At first I couldn't figure out how to pair with my headphones - but I just had to put my headphones in "pairing mode" which for sony wh-1000xm3 is by holding the power button for a few second. After that I was disappointed to find out how low the level of sound is - but it turned out I had to increase the volume from the headphones itself - the sony wh-1000xm3 have touch controls, and now they sound great. I'm tempted to leave one star review, so if you're like me and read only the negative reviews you would see this comment and know that "there is a way". I saw other buyers complaining that it worked only for short period and then it broke - I guess I'll have to test that. Overall I was looking for something small, simple and not very noticeable, that can fit in my headphones case, and I believe I found it. Jan2026 - update Just completed a 24+ journey from the States to Europe and the transmitter worked great . Battery held for over 13hrs flights. Didn't notice any delay in the sound. Admittedly didn't pay attention on the quality of the sound, as I don't expect Hi-fi sound in the plane, but I don't have any complains. My headphones connected immediately, without a problem. At first I panicked, as I couldn't hear anything, but I quickly realised I have to increase the volume from the headphones themselves. For my wh-1000xm3 - the right side of the headphones is touch sensitive and you can increase the volume from there. I aimed for about 50% volume from the headphones and then about 50% from the in-flight media itself.

Edit: This item was earmarked for a certain project, but for whatever other reason, something in the setup was not coming through. The system works without this, so when it didn’t work when I added this, it seemed as though the issue (see original review) was with this new addition. However… I used this on my laptop and listened to it for atleast an hour. So, have to assume there was a disconnect between two otherwise working systems that didn’t like each other. I am changing my review to show that this gadget DOES work in transmit mode. I hardwired it to my computer using the AV cord that came with it, then used a Bluetooth headset. Worked great, AND in stereo sound! Original: I have been trying to use this as a transmitter connected to a Listen receiver in order for me to use Bluetooth earbuds with the system and it will not stay in transmit mode. It stops transmitting after a couple of minutes. I’ve tried unpairing and repairing several times, and it continues to stop transmitting to my Bluetooth earbuds. If it continued to work, it would do exactly what I needed it to do!! The idea is awesome, but it needs to work as advertised and it doesn’t.

As I am sure is the case with many, I purchased this after seeing it listed by the New York Times in their portable BT transmitter review list. It was bought specifically to allow me to transmit BT audio from my computer to my Sony WF-1000XM3 earbuds. As the Sony earbuds only support SBC with these, I wasn't expecting stellar audio quality - I usually use them for lectures or podcast-like content, or for fairly low-bitrate music anyway. I wanted to see if the advantages of true-wireless earbuds were worth the sacrifice in quality before I invested in a more expensive BT transmitter and BT receiver+high-end IEMs. As such, I do not use the receive function, and I do not use the battery on the unit - it is always plugged in via USB. I did briefly test the battery though and can confirm it lasts at least 30m. Note: I went with this type unit, instead of USB, because I wanted to have the ability to test it in multiple environments, including while running and in the car for single-ear usage. Normally, I'd go with a USB solution for computer use in order to avoid the conversion of the audio to and back from analog. Initial Setup Dead simple - I connected the Line Out on my computer to the input on the transmitter, and alternately, the HP (headphones) out on my stereo receiver to the input on the transmitter. I also tried it with a Sansa Clip+ MP3 player. It worked in all cases, though with the WF-1000XM3 I had to keep the input volume on the BT transmitter under 30% and allow the headphones to do the real amplification, as otherwise the audio would distort. BT Setup Fairly simple. I put my earbuds into pairing mode, the transmitter into pairing mode, and they connected within 10s. Afterward, they maintained their connection for the most part, I've had to re-pair a couple times over the last three weeks, but that is mostly a learning curve. Re-pairing is easy - just hold the pairing button down for two seconds and place the receiving device in pairing mode. Range Unpredictable, and sensitive. If the transmitter is located on a desk, at least twelve inches away from other electronics, then the range is remarkable. I can leave the room, pass through the adjacent room, and enter into the next room - a total of maybe thirty feet, through two or three walls - and start to lose audio at the end. This is despite being only five feet from a wireless router. However, if I move the transmitter six inches over so it is next to my monitor, or a couple feet so that it is within three feet of the router, the earbuds will begin to drop out even at ten feet. So it is very sensitive to environment. Audio Quality Decent. Better than I expected, but I haven't used bluetooth audio in ten years. It can be hard to really gauge it, because the Sony WF-1000XM3 are true wireless earbuds and I can't A/B test them to compare BT quality to a cable. I would say that the BT audio quality is equivalent to that produced when my Sony earbuds are connected to my smartphone. While it is decent, it can't compare to wired earbuds of even fairly middling quality. You lose highs and lows. For dialogue content, lectures and the like, no issue. Summary Seems to be a great entry-level transmitter for the average consumer. I'm glad I bought it, because it is reliable and easy to use, and has shown me that the freedom of using wireless earbuds is definitely worth the hit to quality - I can always use my full circumaural headphones if I want to watch a movie or listen critically. Would recommend.

The sound quality was great and it actually was decent price wise. The range and controls worked really well and there is great connectivity with a very well put design.

Not all headphones work. Some BT headphones only play from the right ear, not the left. - example my AKG Y600NC only plays from right side. Tried different 3.5mm cables and didnt fix it. MASSIVE delay from other BT devices and wired. If you use it for something where you are speaking into a mic, and then have the audio out routed to headphones, plugging this device into said headphone jack and in Tx mode, this causes MASSIVE a full 1 sec delay from spoken word to hearing it in your ears. no volume control. no way to know/control the bluetooth device being connected ie; you might have your headphones connect or not, because you cant tell what its connecting to or currently connected to you cant guarantee your headphones will connect. Its impossible to know what other devices in your home may have connected to it. No volume control and it is very quiet. Then you power cycle it, disconnect/reconnect and the volume might be a little to more loud. Convenient size is really about all i can speak to as it doesnt work all that great otherwise since it only plays audio out one headphone on some of my headphones.

An excellent purchase! Worked well. User-friendly.

Writing this after 2 days of use. Relatively easy to set up and works fairly well, at least for now. Several issues I noticed that may/not apply to everyone. For context, I'm using this in TX/Transmitter mode to avoid using cables between my TV and Soundbar. 1) Latency - very minor in SBC mode, but noticeable. I'm unable to cycle to use aptX codecs with lower latency, presuming my soundbar doesn't support it. I double press the #1 button several times (slowly and quickly, but nothing changes). My soundbar has audio delay settings, so should be ok. 2) Every time the soundbar reconnects to bluetooth, it sets the volume to maximum. There's no way to change this setting and it only started to happen with this bluetooth adapter. This is super annoying and makes the soundbar unusable without having a remote onhand to adjust the volume down before scaring everyone. 3) When I try to connect my phone or other device to my soundbar using WiFi to play music, the soundbar auto-reconnects to the bluetooth receiver on TV and stops WiFi playback. This is super annoying and makes the soundbar only usable with TV. If the above doesn't sound like deal-breakers, it may work perfectly well for you. But for my use cases, this will not be acceptable.

This Bluetooth transmitter pairs up much faster and easier than other transmitters I have owned. The sound quality out of my headphones is much better and this transmitter also holds a charge longer than my previous transmitter ever did. So far I am very pleased with this device. Price is competitive and range is good. I would buy again.

1Mii ML300 c'est très facile à l'installation. On suit la notice a été fournie, après 10min. Il fonctionne bien comme indiqué.

Excelente calidad, cumple con lo ofertado. Muy práctico, tamaño ideal Gran opción para conectar 2 aparatos para escuchar audio mediante bluetooth al mismo tiempo, si tu dispositivo no tiene esa opción. Estoy muy feliz con la compra

Worked great with my Monster head phones on a 9 hour flight. Had to charge part way but is expected. A bit of a learning to connect via BT but once I read the instructions and got the correct setting it was perfect each time. I’d recommend to anyone!

C'è poco da fare, Mii è sempre una assoluta garanzia quando si parla di ricevitori bluetooth, ne do comprato tanti, di tanti marchi, l'affidabilità di connessione e la stabilità del segnale dei ricevitori Mii è sempre al top. Dopo aver provato diversi piccoli ricevitori portatili, per associarli a degli auricolari cablati di qualità, e dopo essere rimasto sistematicamente deluso da qualcosa (alcuni non supportavanobrewlmente i protocolli Aptx, alcuni avevano difficoltà di connessione, alcuni un volume troppo basso ecc...) Finalmente mi sono deciso a comprare questo ricevitore Mii perché possiedo già un ricevitore desktop mii che funziona incredibilmente bene e quindi ho dato fiducia al marchio. E ho fatto bene! Tanto per cominciare supporta DAVVERO i protocolli Aptx, e il mio smartphone si connette subito e riconosce immediatamente il protocollo aptxHD, non come altri prodotti che millantano il supporto e poi si connetto o solo in sbc... Il protocollo più basico. Altro vantaggio dei ricevitori Mii è che sono semplicemente super affidabili. Si connettono bene e sistematicamente dopo averli associati, senza problemi, senza disconnessioni, senza tentennamenti, sposti il pulsantino su Rx (ricevitore) e siano connessi in aptx HD al mio smartphone. La batteria dura una eternità usando degli auricolari (nel mio caso i thruthear). Non è presente una regolazione del volume suo dispositivo ma si imposta il volume dal dispositivo che si connette (tipicamente lo smartphone). Il volume è più che abbondante per farvi diventare sordi con auricolari medi, chiaramente non sono uscite adatte a cuffia ad alta impedenza (sono sembra scontato ma meglio specificarlo) Insomma che dire, per me Mii è sinonimo di ricevitori bluetooth di qualità e grande affidabilità, nonostante il prezzo abbordabile. Davvero un peccato che non abbiano acquistato la licenza per il codec ldac, sarebbero stati i miei ricevitori di riferimento assoluto.

I’ve used this a few times already. Once I figured out to press and hold the “1” button till it flashes red/blue, it connected to my Soundcore Liberty earbuds perfectly. Sound quality is decent, with a tiny amount of white noise when audio is quiet(not noticeable otherwise). I watched several hours of Netflix right out of the box without needing to recharge, so it seems the battery life is good. I haven’t yet tried connecting 2 sets of headphones. Well recommended, especially if you have kids and want to actually hear your shows after bed time. ;P
