Sounds good, easy pairing and setup as a receiver or transmitter
Bought this company's prior J33 Bluetooth receiver to allow my car to play audio from my phone since it wasn't built in found that unit worked great. This is a combo receiver/transmitter which works in the car but also works on my home stereo setup, which is from the 1980s. The included RCA cable plugged right in and the range is enough that I can run Bluetooth speakers upstairs from the stereo and record player downstairs. It also works with my Schitt Stack for transmitting audio from my PC. In the car, it does seem to live up to the quoted 8-10 hour battery life as a receiver after about a week of using it on several car rides. Controls are very simple, it connected immediately to everything I tried to pair it with, switching between transmitter mode and receiver mode is likewise very simply done with a switch on the unit, it couldn't be much simpler. I also like the double-sided 3.5 mm jack for the car so the device doesn't flop around at the bottom of my center console (where the Aux port is on my vehicle) like it would if used with a cable, which is a well thought out feature. Very pleased so far as I was with the J33, for a simple and cheap way to add Bluetooth to things that don't have it, I think you'd be hard to do better for this price.

Worth every penny!
Here is a rewritten review with the requested change: I bought this Bluetooth Transmitter Receiver, LAICOMEIN V5.0 2-in-1 Bluetooth Adapter, Wireless Transmitter to use with my computer and headphones. I was impressed by how easy it was to set up and pair with my devices. It has a **low latency** feature that ensures the sound is clear and crisp. It also has a **dual link mode** that allows me to connect two Bluetooth receivers at the same time. I can participate in online training sessions with my colleague without any interference. The battery life is also great. It can last for **up to 10 hours** of continuous use and it can also **stream while charging**. The device is small and lightweight, so I can take it with me when I work remotely. It works well with different devices such as TV, MP3, gym equipment, airplane audio system, etc. I am very happy with this product and I would recommend it to anyone who needs a versatile and reliable Bluetooth transmitter receiver. It is worth every penny!

An excellent product
Let me start by saying the product performs well and, after the first time pairing, connects rapidly. There are a couple of things to know. We purchased this product so that on our upcoming trip my wife could connect to the Airplane on board entertainment with her Airpods. We wanted to test things out. Not having a 747 in our back yard we used a Home Theater receiver that has Bluetooth reception but not transmission. we plugged the BT device into the headphone jack of the receiver. Since I am more experienced with android and my Phonak hearing aids, we tested first with that. The Phonak took forever to get paired. I was about to give up when I picked one of the the Phonak aids up and all of a sudden it was connected. I really don't know what I did. Then we tried the Airpod Pro (2nd Gen). Since we were pairing to a 3rd party device, the Laicomein BT Transmitter (BT TX), I did some research on how to do that. The pods can be paired to many devices but can only connect to one at a time. So we made sure to turn off my wife's IPhone. You turn on pairing on the BT TX and then, leaving the pods in the case, you press the pods setup button for about 5 seconds until it turns white. It flashed green for a second or two and turned white but did not pair. We tried several times without success. Another reviewer had said you have to continue holding the setup button on the pods case. So we tried that. The light flashes green for a few seconds and then turns white and then, after a while, starts flashing green again. That is when it pairs (as shown by the BT TX device green light going from flashing to steady green. After that first attempt, just like with the Phonak, it takes maybe seconds to reconnect the device to the BT TX. There is a delay in the sound transmission. So sound is not synced to the TV screen on our home theater set up. That is a complaint that I see on competing Transmission devices, also. And it isn't all that bad. Sound quality seems to be quite good. All in all, we are pleased with the product. Hopefully, it will work when we get on the plane.

Easy set up and pairing
For the price point, I am pretty impressed with this little thing. I got this Bluetooth transmitter to use with my TV in my bedroom of my shared house so that I could pair it with either headphones or a speaker that would be closer to me in order to keep the sound down. I keep odd hours and didn't want to disturb anyone when I was awake watching shows at 3am. I ended up buying a Bluetooth speaker to pair with it, because I knew I would eventually get irritated with the feeling of wearing headphones. I made sure to buy an aptx low latency Bluetooth speaker to avoid any lag. There was still some lag initially in the sound when I first turned it on, but it seemed to resolve after a minute.or two and if it is still present, it is not noticeable enough to bother me. I love that this was so easy to set up. I am definitely not tech savvy, and I usually struggle with anything that requires set up, but this literally just plugged into my TV and paired once I turned both devices on. It was that easy. The only drawback I see tho this device, which others have also mentioned, is that I have to manually turn it on every time, there is no automatic activation. That means I can't just turn on my TV from across the room and power up my little Bluetooth speaker sitting next to me and start watching my show, I have to disturb my sleeping dog, get out of bed and go across the room, press and hold the power on button on the device to turn it on, and then go back across the room and convince my dog that no, we aren't actually getting up and going out yet. Not my favorite feature for sure. Sometimes it deters me from using it. Other than that, it works great and as intended. If you don't mind manually turning it on each time, I can definitely recommend it.

Great Sized Transmitter/Receiver Kit and a Great Value
I purchased this Kit as a replacement of a years old unit that was much larger and more cumbersome to use. Also, I wanted an updated version, since Bluetooth technology has advanced some over the last several years. What attracted me to this model was the compact size, all the included attachments in an attractive looking kit, and the reasonable price. I use this new unit with the included 3.5 mm male to male connector to attach to my shortwave/ham radio to be able to use my wireless headphones so not to bother my family when in the same room. This small sized unit, and connection method allows the unit to be attached directly to the radio without a cord, so there are no tangling issues, and no requirement to hold the transmitter separately when moving the radio. The transmission is solid, and even stays connected when going from the first floor to the basement without any drops or loss of signal. Since I've had a similar device, it was intuitive and easy to pair with my wireless headphones, and also our entertainment center for late night listening on headphones for concert/music videos/movies when my family is in bed. The manual is fairly well written, but was not really needed in my case. This is an awesome transmitter/receiver kit which includes all connectors need for your possible usage, and at a GREAT Price!

Good but not Better than similar models
Update: Jan 2023: this unit 1) sometimes drops audio for a 1/2 sec, This might be some kind of signal that it is time to recharge the battery? and 2) it takes a long 5-10 second press to power on or off. Sort annoying, even if nbd. The reason to buy this BT adapter is so you can play smart phone music and map directions over your car stereo, and your car stereo has an AUX jack but doesn't have blue tooth built in. I have used several similar BT adapters and this is the best one so far. Here why. This one has a tiny blue power light. Enough to let you know it is powered on, but not obnoxiously large and blinking power light like many others. It's great to have a dedicated "Pause/Play" button on this BT adapter to operate your phone. Much better than trying to get your phone unlocked & onto the right screen so you can press pause, while you are driving. It's a safety issue, and this BT adapter is better & safer than your phone without it. Sound quality for playing phone's music to car stereo is great. It was easy to connect to blue tooth. Works for playing music while your phone mapping app tells you where to turn. The phone will dim down the music while it is telling you where to turn, then return music to previous volume. Perfect. This improved 2 way BT adapter is both a transmitter and a receiver. There is a switch on the side to select either. So it is good in more situations! I personally usually use it to get the BT signal from my phone into the legacy car stereo (which doesn't have BT). You could also use it for a music source that doesn't have BT to send that signal to a BT speaker. For example, say your slightly older TV set doesn't have Blueooth, but you'd like to hear the TV on your BlueTooth speaker. This will do that! Just plug the BT adapter into your TV audio out. It's a bridge between favorite older equipment & newer BT devices. There is a built-in mic on the BT adapter so you can make hands-free phone calls using it and your car stereo. Just press the big play/pause button on this BT adapter to answer the call. You can hear your caller over your car speakers really well. The built-in mic is nothing special, about the same as others in this price category. Useful for ordinary hands-free calls, but the mic audio won't impress anyone. Callers said they could hear me ok, but at their end, my phone audio quality could be better. YMMV. My rating for sound quality is for playing music. The BT adapter has a built in battery. In my experience on a recent road trip, the battery lasted about 300 miles of music. Then I plugged it into power. When the BT battery is near dead, it will signal that status by a quick 1/2 second of silence a couple of times before it quits. At least I think that is what that was about. This BT Adapter is USB-C rechargeable. It's OK to leave it plugged into USB power if that is convenient for you, or charge & run off the internal battery. This product includes a short metal dual male plug to plug directly into the AUX port. That works fine. I wanted to find out something, so ran a headphone extension cable (dual male stereo) from my car stereo "aux" jack along the dash board & up to my sun visor, to the BT adapter, with the idea that would get the mic closer to my head which might pick up better audio for phone calls.

Device audio on stereo with no built-in bluetooth connection, tape deck, or radio static!
I personally was thrilled to discover Laicomein's Bluetooth Transmitter Receiver, especially by the novelty of its audio jack stereo connection which allowed me to plug directly into my car stereo without shuffling through the radio stations in order to broadcast to the one with the most static. No longer are my songs and podcasts interrupted by an improving radio signal, nor am I forced to repeatedly reset the station as I drive through various towns on a road trip. Moreover, its small, sleek design allows it to fit nicely into your stereo's aux port without blocking your buttons or display in any way. No tape deck? No problem! The audio jack feature also eliminates the need for virtually obsolete tech like a cassette player--such as I used to depend on in order to listen to the music on my phone via my car stereo in the past, preferring the corded cassette contraption to the aforementioned radio transmitters with their inconsistent sound quality, because at least it offered a direct connection. Therefore, when I purchased my newest vehicle sans tape deck, I lamented the loss of this convenient device-to-stereo audio connection and reluctantly returned to the FM transmitters that had frustrated me in the past... That is, until I discovered this nifty little product! Not only does it deliver my preferred direct connection, but it does so without unsightly, tangly wires dangling in front of the controls and display thanks to its bluetooth connectivity (and incidentally solving the problem of the incompatible iPhone audio jack that requires an adaptor for use with any non-apple accessory). Overall, I find it to be an affordably priced, perfect little package for its purpose!

This is an amazing receiver
I was a bit skeptical at first given my numerous purchases for my car, but let me tell you...I AM BLOWN AWAY!!! This is by far the best Bluetooth receiver that I have ever used. The sound quality is amazing, the phone calls come over loud and clear and I don't have to blast my radio to hear the call and for the caller to hear me! I am so incredibly happy with the quality of this product. Such a game changer for my jeep! I have collected all my other receivers and placed then in a box for backups in the event that something were to happen to this one (and I would most likely just purchase a new one from this company). Shipping was incredibly fast. I have been using this device everyday for the past week and I'm so incredibly happy!! It charges fast and well, and I now look forward to getting in my Jeep and going because I have the ability to listen to my tunes, answer calls, and not have to worry about reception issues or the life of the device dwindling due to usage. If you're on the fence...get this product, give it a try, I promise you'll probably be just as happy as I am. It also is very easy to connect to your car, came with different connector plugs, and I have also hooked this up to my in home system. I could not be happier!!! Thank you so much!!

Small but mighty!
My hearing is not what it was and I have been trying to find a solution to the issue of TV listening while my treadmill without blasting the volume and driving my husband, pets and neigbours crazy. This little gadget has brought peace and happiness to my workouts....an affordable, unobstrusive little treasure. It was a brief learning curve for me to figure out how to set it up on my TV as I had trouble finding the right sound outlet. I also had to change the settings on my TV so that the sound bar was disabled and the TV sound was the default source. This could be annoying if you want to use the sound bar for movie effects or for playing music, but it's only a case of switching the TV settings back again ; not a big deal. Once paired with my headphones, which took a few attempts initially, it worked like a charm. The sound comes from both the TV and the headphones so someone else could watch at the same time, although there is a slight time lag between the TV sound and the headphone sound. I just turn down the TV volume and listen to the TV through my headphones. I'm so impressed, I'm going to get another adapter for my kitchen TV so I can listen to whatever I'm watching while preparing food, washing dishes or whatever without the need to have the volume up loud on the TV. I could use the device in both areas, but would rather have a dedicated one to save any hassle. The sound is so much clearer through the headphones too and has a long range, so doesn't break up when I leave the room, even out my yard. All in all, this Bluetooth adapter is the best and cheapest hearing assistance out there, especially if you are age and hearing challenged like me 😂

Bluetooth device purchase
I liked what I received and it was pretty easy to set up. However, one needs to set the bluetooth and connect every time you switchit. I biught this product from Amazon.ae, on amazon.com purchase. i received a 20$ gift voucher, however this was not accepted as it was a amazon.ae purchase and not from amazon.com. Amazon.ae should accept the $20 gift card and should process the voucher, but the teller did not have a clue what needs to done.

Great product.
Bought this to connect to the stereo in an older RV. I love this thing, it works great. I can now stream anything from my phone. Pairs and connects easily.

Two Bluetooth devices at once
A typical BT transmitter. It paired easily with a Sonos Roam and NAD 3045. Not having a way to compare with similar devices, I can only say that the sound is good and seems to be faithfully transmitted with no drop-out or fading. The volume control seems a bit erratic, as I had to turn it down completely and bring it back to a reasonable level a few times before I was satisfied with the output. (It may have been because the unit was not fully charged?) Recommended.
