Answers to Mostly Asked Questions:

Question The volume is too low/How do I adjust the volume on my AirPods?
Answer 1 To adjust the volume of your Lavales Bluetooth Adapter, you need to adjust two things: the input volume and the headphone volume. To change the input volume, use the volume controls on the device that you plugged the adapter into. For example, if you are using an in-flight entertainment system, you can adjust the volume using the on-screen or remote control.
Answer 2 To change the volume of your headphones, you use the controls on the headphones themselves. But if you have AirPods, which don't have these controls, you can adjust the volume on your iPhone or iPad and then reconnect back your AirPods to Lavales Bluetooth transmitter.
Mostly Customer Asked What if I can't connect my Bluetooth Adapter to my Bluetooth headphones or speakers?
Solution 1. Turn off Bluetooth on all devices in your house. Make sure your headphones or speakers are not connected to any other device while pairing with Lavales Bluetooth Adapter for the first time. Keep the devices close to each other (within 1 meter) during pairing.
Solution 2. If they still won't connect, reset both the Lavales Bluetooth Adapter and your headphones/speakers to the original settings.
Software Reset Press and hold HEADPHONE 1 Button for about 7 seconds until the LED indicator flash PURPLE light for 3 times, then the device will restart and clear the list of paired device, and the factory settings will be restored successfully.
Question Why the audio lag still here when use this Low latency Lavales Bluetooth adapter with my Bluetooth headphones?
Answer To reduce delays in sound, your headphones must have aptX-Low Latency or aptX-Adaptive technology. If not, you can't experience low latency mode. Keep in mind, Airpods don't support low latency mode. RX-Mode doesn't support aptX-Low Latency but does support aptX-Adaptive.
Question Why I plug 3.5mm and Type-C to USB cable to same device but no sound at all?
Answer The Type-C port can also be used for transferring data. But if you connect both 3.5mm and Type-C to one device, there will be no sound. So, try charging Lavales Bluetooth Adapter with an additional charger.
Question How to pair with 2 headphones in TX Mode?
Answer After you successuflly pair with your headphone, long press the Pairing Button for 2 seconds, the LED indicator will flash red and blue again, made your another headphone into paring mode and let them pairing, after both headphones successfully paired, the led will show purple light timely, it means succeed.
Question Does it work with any TV?
Answer It suitable with TV with 3.5mm Jack/Headphone Jack/RCA Jack. Please make sure your TV has above mentioned audio jack.
Warning: 1. ML301 is not suitable for use with music instruments such as electronic pianos or guitars. 2. The aptX-Low Latency/Adaptive/HD feature can only be utilized if your receiving device supports those functions.

Bought this transmitter and a receiver for my full analog set and made my receiver/record player and wired speakers a full bluetooth set. Gave in slightly on sound but honestly not that much. Totally worth it for the surround sound feeling

Bought this for our trailer so we can connect our phones to it to play music. Great quality, works great and has so far lasted a summer of camping.

Theres a small static muffle sound when it’s connected and there isn’t anything playing like a movie or video - it doesn’t affect the sound when watching anything but in quiet scenes you can hear it but it’s quiet, I could see it being annoying if you keep your airpods in when pausing videos but it doesn’t bother me since I take my airpods out when i’m done watching a movie or show/video. Overall, does it’s job and easy to use.

Très satisfait de l'efficacité du produit. Le système cinema-maison que je possède est vieux et ne connait pas l'existence du bluetooth!!! Maintenant, avec ce transmetteur je peux écouter tout ce qui est branché dessus avec mon casque bluetooth au volume que je veux sans déranger personne autour et le son est excellent.

I use these with a cheap FM receiver for sports arenas that simulcast and FM play by play, and they work perfect.

While my iPhone paired immediately with this device, even after trying the manufacturer’s troubleshooting suggestions several times I still couldn’t hear anything using my AirPods on a Delta flight - and both the entertainment system and my AirPods worked fine otherwise. This purchase was an unfortunate waste of my money and time trying to make these work.

LOVE this little gadget! My roku smart tv is old enough it doesn't have Bluetooth. This little guy is easy to use and allows me to pair any of my Bluetooth heads phones with it so I can listen to my TV via headphones.Also!Great for the iphones/smart phones that lack a headphone jack. You can switch it to a receiver and thus Bluetooth you phone to any headphone jack reciever/audio output item. - super great!Best value for money I've spent in a long time.

I have tried several brands of Bluetooth transmitters. I use them to transfer my Theatro to my hearing aids. Connects easy, lasts longer per charge than any other transmitter I have tried. Highly recommended

Now, this is what II call a proper stereo BT transmitter. I firstly tried a cheaper product and I was really disappointed that it was transmitting sound in mono only... What? really? in 2025?So to the rescue was this Lavales BT transmitter. Not only transmits in stereo sound but you can adjust it to different codec modes. I was able to use the APTX HD with my Headphones... Awesome!!!
