Connect Multiple Headphones

With the Audiplex 2403s, you and your family can enjoy an outdoor movie party or a silent concert without disturbing the neighbors; the 2403s wireless kit lets you have multiple headphones connected to one audio source, and even though it only comes with three receivers, it is scalable. You can purchase additional receivers and connect up to 100 of them to the same transmitter.
Universally Compatible

The transmitter dongle of the 2403s can transmit audio from any audio device that outputs audio through an AUX or optical jack – TV, Projector, Stereo Receiver (via 6.35mm adapter), Blu-ray Player and even some electric musical instruments. The receiver dongles can be used with any audio “receiving” device that supports AUX, for instance, headphones or speakers.
All In-Sync, No Audio Lag

The Audiplex wireless kit uses 2.4Ghz technology (NOT Bluetooth) for broadcasting audio; it reduces the audio lag down to 30ms, significantly less than the 220ms of Standard Bluetooth and the 40ms of aptX Low Latency. You will experience NO lip-sync delay no matter how many receivers you connect, making it your go-to choice for watching movies with family & friends.
Independent Volume Control

We all hear differently, and the volume level that works for one person does not always work for another. The Avantree 2403s Wireless Audio System solves this issue by allowing each receiver dongle to adjust the connected headphone/speaker’s volume independently, letting the user personalize his/her volume level without affecting the other users (dongles).
Extended yet Stable Range

The 2.4Ghz wireless technology in the Avantree Audiplex set provides stable & reliable connection of up to 100 ft/30 m indoors and outdoors (tested with 20 receiver dongles). Feel free to move around, the connection will remain, and you won’t miss a thing. However, please note that physical obstacles may negatively affect the actual range.

Overall good

Today, I received my Audiplex. I tested it and it works very well. The only things that I wish it had are: • Ability to control volume by Handsfree buttons. • A type C to 3.5 mm cable for phones. In an email from Avantree, they said if I my suggestions are adopted, I will receive one for free to show appreciation. 😃 Am I eligible for that?🤗

update on Audiplex 2403s

Update to my previous review, by putting a small amplifier between the pickup on our mixer and the 2403s transmitter we were able to get the increased volume we desired. Now I can hear without my hearing aids (which would normally be removed to prevent feedback) with plenty of volume and no distortion. I am very satisfied with the system with one exception: it is very difficult to read the button designations on the receivers. One feature that I consider a plus is you can use any headset that can use a 1/8-inch connector which is fairly standard. I recommend this product!

Audiplex 2403s

I purchased the equipment for the hard of hearing at our small church. I believe the equipment is working as advertised but I cannot get the volume one would expect for someone with difficulty hearing. I myself have a serious loss but with hearing aids on I cannot hear much better with or without the equipment. I am still working with getting more volume into the transmitter. When I connect the transmitter to my computer I am able to increase the volume into and out of the transmitter. Our sound system does not have optical output so I use aux from an earphone output. It just isn't getting there. I like the approach the equipment presents but for the hard of hearing it is not just a case of getting the sound closer to the ear. There needs to be some db increase. I haven't given up yet. I know you have other equipment for this purpose but not sure it would do better for my application. I would not discourage anyone from purchasing and trying the system out.
