Avantree Audiplex – Wireless Audio Transmitter & Multiple Receivers Set for AV Receivers, Projectors, PA Systems, Assistive Listening System for Hearing Support, Group Listening in Church Home Theater

I have ten receivers which have replaced twisted-pair wire running through the crawl-space under the house to all rooms. All are working flawlessly, with a few comments. One in the garage is about 60 feet and four walls away from the transmitter and I have to lay it just right for it to receive, but that is not a problem, positioned just right it works fine. Incidentally, I put that one in a baggie to protect it from dust. One outside on the patio is about 50 feet, two inside walls, and one brick wall away. It doesn't receive very well behind the brick wall, but there's a window, and when I lay the receiver on the window sill it works. Again, not a problem, and I'd not have expected it to work well through brick. The receivers are a bit fiddly to pair, nothing consequential, you may have to try two or three times, but they all pair quickly. Some of my speakers are switched, i.e. when I turn the lights off in a room the speakers go off. I plugged the receiver chargers into the same circuit and learned that, when the battery runs down and the receiver turns off, then when power is turned back on, the receiver doesn't work until I turn the on-off switch on the receiver off and back on. I resolved this by plugging the receiver charger into an always-hot outlet. So, after a few days, all is well. If they continue to work without failure I'll be most happy.

I saw one comment somewhere that said they were getting latency well trying to pair their Bluetooth headset with these, I don't know what they're talking about because these are not Bluetooth. Well the audio quality isn't crisp I would say it's 95% acceptable and I would love to see what a revision they could do. They're basically analog? No latency! There's lots of scenarios I can think of where I want One Source to many. I was using these will mixing Sound and I was having issues with my low latency Bluetooth transmitter receiver set up so I grab these out of my bag. I was in a big metal square box I walked into the other room another big metal square box to pick up my food order. I was over 500+ feet away before I started noticing any drop outs on the other side of a metal wall!!!!!!!!!!! I still can't believe they worked. I purchased the original version with optical outputs on the receivers in case anybody else is scratching their heads looking at the pictures they did exist. I purchased a second set rather than an expanded set figured the extra transmitter would give me options. I could see them wanting to cost cut, I just hope they make that other receiver available as an extra add-on. I could see a few scenarios where you might want to send optical audio to two different sets of speakers. I can also see weird things like running a dedicated optical DAC with volume control next to the sofa. One point I was thinking of grabbing the optical audio off of the DVD player at my local theater down to a private set of headphones but now that they have finally raised enough money for surroundsound the 1900s speaker has been officially retired and the audio sounds great. I have a few other ideas for these devices one of them is for use on a Sound bag and handing out receivers for interested parties to listen (also thinking of sending a slightly lower audio quality with FM transmitter with the benefit of anybody can bring a radio). And the current situation I'm experimenting with sending Wireless time code, yes it does work although I do need a pad on the signal otherwise it modulates the opposite channel which I am planning to send back up audio over to cameras. At some point I'm gonna get around to making a video comparing different Wireless products audio latency and distance. And to be fair I've had a couple of times where there was probably just way too much interference where are the distance was probably closer to 100 feet outdoors but I was also running consumer wireless guitar units and prosumer wireless microphones and fighting with multiple channels of 2.4 GHz Wi-Fi. I still got Signal through although the orientation and distance was a bit more finicky. Battery life has been great occasionally the switches will get bumped I need to find a better storage mechanism but with three receivers I have a 1 and 4 chance that it's going to be the transmitter. but that can be plugged in well they can all be plugged in while used. When charged battery life is very good I have to remind myself to charge them every so often usually I just try and charge them before I know I'm gonna use it and definitely charge it after I use it but I have not encountered one dying while being used. Don't know what else to say it's the kind of thing that I've been wanting and was actually looking to attempt to build out of premade parts. I took the gamble when they first came out at the price they were and I think the price came down a little bit and now I look at it going no brainer. Well-made, there's solid and I'll probably be buying another set.

I don't know why the amazon review wanted me to comment on Bluetooth functionality, which this product does not have that feature. What it can do is allow you to connect to a line-out and broadcast that to multiple devices. I used to for PA and karaoke, both of which worked great. I did not notice any real loss of quality or volume. Range wise, I used it in a large warehouse and no trouble at all and latency was minimal. With non-stop music playing the devices batteries ran out at about 3hrs. Pairing is easy and the manual has clear and easy instructions.

Works as advertised, but has poor audio quality. Discovered that all of these wireless Bluetooth transmitters, regardless of brand, suffer the same problem. It's like listening to music from a low bitrate MP3 file. Would work fine for a PA system or tour guide system. Not so great if you're at all concerned with music quality.

I was throwing a large indoor/outdoor party and I was streaming audio from my TV. In my regular set up, I have the TV streaming audio through a home theater system. I purchased this product and I used the provided optical cord from the TV to the transmitter, then used a receiver into the RCA input of my home theater system and another receiver into the RCA input of the external speaker that was placed outside. It worked perfect and provided the same exact sound inside and outside so as you traveled between both, you heard the exact same song. The external speaker was about 12 feet from the transmitter that was next to the TV, through an exterior wall. If I had a third speaker I could have set that up too. If you’re looking for something similar, I STRONGLY recommend this product!

Very user friendly easy to set up. Perfect solution for someone who struggles to hear the television clearly. Receiver end has volume controls separate from the TV volume. With good quality headphones, your favorite movies will come to life. Also great for outdoor movie projector with a range of 100 feet. Wireless headphones not compatible!

When I first came across this kit, I was extremely skeptical. While Avantree is a brand with which I was familiar (mainly from seeing it all over Amazon), I didn't have a high view of it. But at the same time, I knew the concept they were promoting was sound because I had just bought a pair of Aiaiai TMA-2 Wireless+ headphones, which operate wirelessly either via Bluetooth or 2.4Ghz like this kit. I love using the 2.4Ghz transmitter with those headphones because of the non-noticeable (to me) latency and the improved sound quality over Bluetooth. However, that transmitter works only with those headphones. The idea of a kit that would allow me to use any headphones that can function with a standard 3.5mm audio cable was very enticing. It was only a little bit more cumbersome than using a Bluetooth transmiter/receiver like an EarStudio ES100, Fiio BTR5, or Qudelix 5K (all of which I have and like) in that you also have to connect a dongle to the source. But if it could offer reduced latency and no compression, then the disadvantage of the extra dongle would be worth it to me for certain scenarios. I looked all over for reviews but couldn't find more than one and that person used them mainly for outdoor movie watching. And to be fair, the marketing materials make a lot of this scenario. The fact that you can connect multiple receivers to one transmitter is a plus. Most Bluetooth receivers allow only for connection to 2 devices at the same time. Being able to connect many more receivers (assuming you're willing to buy more if you need more than the 3 that come in this kit) would be a plus for a scenario like that. But I'm mainly interested in monitoring situations, such as monitoring the audio coming from my microphone during Zoom/Teams calls, recording sessions, or simply using headphones to connect to my digital piano and keyboards. I have been using a relatively complex setup involving a Creative X3 gaming DAC, a Fiio BTA30 transmitter/receiver connected via optical and a Fiio BTR5 BT receiver into which I plugged my headphones - just so I could not be attached to my desk when iistening to conference calls where I knew I wouldn't have to talk but didn't want to use speakers. It was even tolerable to use that setup when I did need to speak; the latency was noticeable using AptX LL, but it was tolerable. Where this kit exceeds my BT setup by far is in latency. It isn't perceivable to me for normal use. The sound is crystal clear and the need to have a dongle connected to my headphone output isn't a problem since it's just sitting on my desk and takes up less room than my Fiio BT30. I'm used to strapping my Fiio BTR5 to a lanyard and wearing it around my neck with my headphones plugged into it and this is more or less the exact same situation. The dongle is a bit bigger, but not so much that it's annoying. The kit comes with clips you can stick to the back of a receiver and it has a hole at the top where I attach the clip of my lanyard. Where this setup does not exceed my BT setup is in battery life. Even my FIio BTR5, whose battery life seems to be the worst of my collection (but is the only one that supports AptX LL so I was resigned to using it), will last through most of a workday being on and connected the whole time. But the Avantree transmitter will usually die sometime shortly after lunch on an average day of a couple of morning conference calls. The receiver will usually last until an hour or two before "quitting time". The nice thing about having this kit is I can swap out receivers when one dies. And since the Fiio BTA30 had to be plugged in to work, I can't really hold the short battery life against the transmitter too much because it does work while plugged in, so when the red light comes on, I can plug it in and keep going if I need to. What I've learned to do so far is just plug it in during lunch - assuming I don't have lunch meetings - and return to battery power for the afternoon. I know in general it's not best to keep battery-powered items plugged in all the time, but I also know that if it ever gets to the place where it no longer holds a reasonably usable charge, this would also be an option. One of the other benefits of using this kit vs. a BT transmitter/receiver is the flexibility. You don't need to pair any BT devices. If the device has an aux port, you just plug it in. If it's a phone, tablet, or computer without a headphone jack, you can use a headphone adapter. You can even use a high-quality dongle DAC like an AudioQuest DragonFly to get better audio. You can't connect to 2 sources simultaneously, but switching doesn't require re-pairing or fiddling with BT settings. And in some cases, the range is better as well. With a solid bluetooth connection I can sometimes go into my basement and not lose the connection, but most of the time I do. With this kit, I was able to roam most of my house without issues. It definitely outperforms the TMA-2 transmitter on range. With the TMA-2 transmitter, I can't even go into my kitchen to make tea 2 rooms away without losing connection but with this kit, I might not even lose connection if I start up the microwave, depending on where I stand in the kitchen. The connection strength is solid. Battery life is really my biggest complaint. The sound quality is better than I expected; there is very little hiss at the default setting although you will hear more if you increase the volume on the receiver. However, even a few cilcks of volume on the receiver doesn't result in hiss as loud as the hiss on the TMA-2 at the default setting. In terms of clean audio, this is pretty good, even with sensitive in-ear monitors. It isn't quite as clean as a good BT dongle like the ones I've previously mentioned, but I think you're trading the possibility of a little bit more hiss for an increase in sound quality because you don't have the compressed audio you get with BT. This is a trade I'm willing to make. And you can avoid this problem for the most part by increasing volume at the source and not at the receiver and if someone else needs it quieter on their receiver, going softer won't increase the hiss. Value is going to be subjective but my previous setup involved plugging an optical cable from my Creative X3 to my Fiio BTA30 and then connecting my Fiio BTR5 to the BTA30 via AptX LL. This resulted in latency I could hear but tolerate. Now I plug the Avantree transmitter into the X3, turn on a receiver and plug in my headphones and have no discernible latency. I don't even have the BTA30 on my desk anymore and I haven't used the BTR5 since I bought this as I bought the BTR5 only to pair with the BTA30. Yes, the transmitter battery life isn't as good but you can plug in the transmitter and you have extra receivers to compensate. The BTA30 cost me $90 and the BTR5 cost me $110. This Avantree kit cost me $160. For me and how I use these devices, I think this Avantree kit is a better value than my previous setup and I love how easy it is to use it with anything else with a 3.5mm plug. Despite having an extra item to plug in, it still feels more freeing to me. Overall, I'm really impressed with this kit. I do wish the battery life was longer, but it's long enough for a full-length movie if you're using it that way and it's long enough for the average conference call or a few podcasts/albums if you're using it that way. You may just need to keep a charging cable and/or battery pack nearby if you aim to use it for longer than the rated battery life. If you understand the pros and cons and are willing to accept them, I highly recommend this kit. I may actually buy a second kit for my husband so he can have a wireless option for monitoring his electronic drums or his DJ setup.

This set is a bit pricey and very specific gear, but they work fantasticly together to provide a super low lag sound field for parties. I bought an extra reciever and use the transmitter connected to RCA's on my TV audio output to have 5 indoor and outdoor speakers. It sounds great!
