2025 Upgraded Pro Bluetooth 5.4 Transmitter Receiver,2-in-1 Airplane Wireless Adapter for Flight,TV,PC,Gym,Switch,Supports to 2 AirPods/Headphones;Audio AUX Receiver for Car/Home Stereo

I initially purchased a Beeitzie 2025 Upgraded Pro Bluetooth 5.4 Transmitter-Receiver in February 2025, but I didn't get around to using it until this past week for the purpose of remotely monitoring audio input during a recording session. Firstly, I was very impressed by how well-organized, well-written (in English), clear, and detailed the instructions were in comparison with those for other electronic products that I have purchased (i.e., ones that I had to fiddle with in order to learn of their capabilities and functions). In contrast, I understood immediately how to properly use the Beeitzie Bluetooth Transmitter-Receiver and it performed excellently when using the transmission feature for my use-case. In particular, the instruction tips indicated that connection problems may be related to other nearby actively-transmitting Bluetooth devices. This tip became important when, during my first use, the transmitter wasn't connecting with my Bluetooth speaker. I remembered this tip and searched my nearby devices to discover that I had a computer and smart phone also transmitting Bluetooth, one of which had already connected with the speaker. After I turned these other devices off, the Beeitzie transmitter immediately connected with the speaker and the recording session monitoring proceeded very well afterward- lesson learned!I was so impressed with the Beeitzie Bluetooth Transmitter-Receiver that I bought 2 more today!

Very much worth the purchase! The setup was easy, and it worked well on my flight.Some small complaints I have is that a) there was the tiniest bit of additional latency due to the Bluetooth connection (likely barely perceptible to most people), b) every once in a while, the tiniest bit of static would come through, and c) there was only one way to fit the two-pronged plug into the port at my airplane seat (if I tried to plug it in the other way, the cable ran into the plastic edge on the left side of the port, was on the back of the seat in front of me, which prevented you from plugging it in fully). This was a problem because I’m pretty sure that it reversed the earbuds that the stereo sound was going to. The impact of that was that I might see someone say something on the right side of the screen I was watching, but hear the sound coming through prominently in the left earbud. For further context, I was watching Wicked, and there were several split screen moments where this sound-to-image mismatch was more obvious than it would’ve been otherwise. While you do have the option of only plugging in the single headphone jack into one of the two prongs, I felt like the sound experience I was getting with the two prong plug-in was richer, so I kept using it despite the audio discrepancy.Regardless of those three minor complaints, the listening experience was far superior on my noise-canceling Bluetooth headphones than it would’ve been on the cheap airplane headphones, so I am very glad I got this nifty little device.

This is an amazing value! I've used a variety of bt headphone amps, ranging from the super cheap to quite pricy, and this is as good as anything! The sound quality is quite frankly amazing. While I think the sound quality differences are going to be fairly similar in any bluetooth amp you get, the quality of the sub bass and overall open sound is as good as anything I've heard on units costing over $100.What really sets this apart is how versatile it is. It easily connects to two sources. It easily switches between receiving and transmitting. It also pairs very easily - maybe the most effortless bt pairing of any device I've had.It's been extremely useful:-transmitting from the tv on an airplane to my noise cancelling ear buds-transmitting to headphones from my turntable-making wired headphones wirelessI also like the controls: unlike almost every other competing device where a long press of the rocker changes the track, and a short press changes the volume, this one is opposite. Why is that good? Because you usually want to change the track more often, and if I need to change the volume, I usually change it significantly, when I would press for a while anyways. Plus, changing volume on my phone or whatever I'm playing from is usually easier than changing tracks on it is.My only possible improvement would be to have a female jack on it and then supply a short male to male cord. Only because I'm plugging a cord into it more than I'm plugging it into something. But shipping it with a female-to-female adapter was a nice touch.

This little device is awesome! I have lamented that my 40 year old (high end at the time) Kenwood stero is not Bluetooth capable, but it wasn’t invented back then. I purchased an adapter for a couple bucks to plug this device into and then into the large “headphone jack” of the CD player. Viola! I have my tunes on Bluetooth now! I can throw 5 or 6 CD’s on the system and it now connects with my JBL Bluetooth speaker that I can take out onto the porch with me, or anywhere around the house! I have not tested the range to determine the max, but it’s so far great by me! I had looked for a replacement system, but don’t want to spend several hundred dollars when I have a really nice one - old but really good. Now for under $10, it’s revitalized and I have my summer tunes to enjoy again!

Plug, Pair & Play in under a minute! Excellent audio quality with no glitches. The photo shows it installed in my 2000 Excursion playing an aftermarket SiriusXM receiver into an aftermarket USB battery-powered Bluetooth® amplifier/speaker. While it looks a little messy, it works just fine with plenty of volume (for this deaf old geezer). The cassette transport in the car gradually died over the years, so the cassette adapter stopped working and this was a reasonable workaround.
