C28 Bluetooth Transmitter Receiver, 3.5mm Aux Audio Adapter for Car, Plane | 2-in-1 Bluetooth 5.0, Hands-free Call with Car Stereo, TV, Speaker, Headphones, MP3 Player. Detachable 3.5mm Plug. No App

bought it to add Bluetooth to an older car stereo, and it worked right out of the box. Super easy setup — basically plug and play like advertised, no app, no complicated pairing process. Connection has been stable, sound quality is surprisingly good for a small adapter like this, and switching between transmitter and receiver mode is very convenient. I’ve also used it with a speaker and an older TV, and it did the job without issues. What I like most is it gives older devices new life without spending a lot.

The C28 worked well-when it worked. Had a good 4 1/2 years of use out of it, then it just stopped working. When it worked, connectivity was simple. I could play music from my phone, plug the device into the aux input of my bass amp, plug my headphones into the phones jack, then play my bass and music at the same time with my headphones. Good purchase, will buy the upgraded version. Audio quality was good through this device.

I have a iPod (not Bluetooth capable) I wanted to use with a portable Bluetooth speaker. I wanted to use this transmitter to connect the two. However, it doesn't work. When I got this thing, the battery was flat. After charging it with the micro USB port (no USB-C here). I was able to turn it on and get it connected to my speaker... But no music would play from my speaker. After checking the volume and repairing it a few times without success. I tried pairing it to my Bluetooth headphones. They paired and I could Hear the Music.... in mono-sound. These thing are advertised as being "stereo " but they don't use stereo sound. I paid money for this thing but it can't play Money by Pink Floyd correctly. This issue is likely why it didn't work correctly with my speaker. I was using a JBL Flip 5, that is a mono-speaker and I am guessing that was some how the issue? both ear buds played music in sync when I tried them. The sound quality could only be described as serviceable. Not good, but not That bad. The instruction are near impossible to read and they an brief to uselessness and in size 3 font. My thumbnail is bigger then a short paragraph of the instructions, They are Tiny!! P.S. Yes the iPod puts out a stereo sound signal I checked using a old wired set of head phones.

I bought this because I want to use my iPod Classic in my 2024 Kia Niro. Unfortunately, the Niro tells me to look at the device's screen for the Niro's name, so I can't connect. Apparently Kia thinks people connect only smartphones via Bluetooth. If your car works the same way, you're stuck. My Yamaha receiver, on the other hand, just connects to it, as does my Harmon Karmon Studio 4 speaker, so I can use the iPod here in the house without headphones. The device shows up on the receiver as "C26." The device itself is pretty compact, but the double-ended male connector makes it stick really far out from the iPod. You can't just shove the pair in a pocket. The connection into the device is a tight fit, so you have to push with a little "oomph" to make sure it's fully seated. I don't like multifunction buttons; on this device, the power button is also the BT connect button. There is a slider to switch between transmit (TX) and receive (RX). Can't speak to the battery life, as I haven't had it that long.

I am happy with this small yet powerful device. Now, I am able to connect my AirPods with an airplane screen wirelessly without paying for a premium price such as iFly brand. The transmission is fast and clear. Easy to setup and no problem at all.

Great little product. I have a receiver type of one in my car and have used it for YEARS so I can listen to my phone thru my car speakers using bluetooth but I needed the Transmitter function this one has so I can hook it up to my Denon stereo receiver and listen to my JVC turntable using my AKG wireless/bluetooth headphones. Also works well with my bluetooth wireless earbuds. The little Transmitter/Receiver switch on the side has to be switched to the right setting - and it's nearly impossible to see the "Tx", "Rx" stamped on it - had to use a magnifying glass. Also - this has a mini-stereo plug - so you'll need one of those 1/4" stereo to 1/8" stereo converters because most vintage stereo receivers (like my Sony, Sansui and this Denon) all have 1/4" stereo plugs. I have accumulated lots of those over the years so I didn't buy one so I cannot recommend one - but you'll want one that has the 1/4" stereo male to 1/8" female connector - and don't get the ones with the 1/8" female connectors that 'screw in' - oh - I'll just go to Amazon and find the one you want - this one: VCE 6.35mm (1/4 inch) Male to 3.5mm (1/8 inch) Female Stereo Audio Jack Adapter. $7 for two gold plated ones. Hmm. I may buy these - they are probably better than the ones I have!

I listen to local radio in the morning, to catch local news. Bought this to use with my radio in the morning when I walk my dog. Go tired of having the wired earbud get in the way all the time. Charged it up when it came in and used it the next morning. Paired it with my Galaxy Buds+. Turned everything off and they paired back up immediately when I turned it all back on. That part works well. Had to move the volume on the radio to 25 to get the same volume as 10 with earbuds. Sound quality/volume poor. Put radio in my pocket, sound would cut in and out as I walked. I moved it to my waist (tucked it in to my waistband) and it worked a little better. Every time my arm would swing over the device the connection would get weak/disconnect. If the radio just lies on the desk or table it works fine but movement causes issues. Connection quality below average to poor. I have used it two mornings now and the battery lasts about 2 hours. Not sure where they get 4 hour battery life. Not really useless for me as my walks are not that long but I continue to use it back in the house while drinking my coffee, waiting for work to start, etc. But it does not last long enough. I turned it on at 6:10am this morning, got my first battery low beep at 8:15am. Battery life very poor. Overall a 2, I cannot recommend this.

Depois de 8 meses, parou de funcionar

Dura poco la batería sin embargo funciona sin ningún problema Establece bien la conexión

Hace lo que ofrece. Aunque las instrucciones están en chino, es intuitivo. Todo es por el color de los focos

El producto funciona, la quería para conectar como parlante a mi Alexa. Pero el detalle que me parece molesto es que al encenderlo, funciona bien, pero con el tiempo el sonido va ganando retraso que con 20 minutos, se nota mucho el atraso. Para solucionarlo, tengo que desconconectar del Bluetooth y volverlo a conectar; o apagar el dispositivo y volverlo a encender.
