Review on 🎧 SONRU Aux Bluetooth Adapter for Car/Home Stereo/Wired Headphones: 5.0 Bluetooth Receiver with Fast Charging, Long Standby, and Long Distance Transmission - Enhance Your Audio Experience! by Stanley Redline

TLDR; I have had many different bluetooth receivers and this one sounds great. You'll have to spend a lot more money to get the best, and *most people* won't hear the difference. I'm a bit obsessed with the devices I plug my headphones into. I researched and bought MP3 players before you could buy Bluetooth devices when you burned your MP3s to CD (then Zen Xtra, Rio Karma, about a dozen Sansa clips with Rockbox, etc.). I had Quedelix, EarStudio and used Fiio uBTR, BTR3, BTR3K. I wanted to try some of these new low cost receivers. I bought one from Anker, 1Mii, Sonruu (not this one, older model), Laicomein and Beeitzie. I gave them all back. Of these, Sonruu, Anker, and Beeitzie were pretty good. Laicomein was a bit behind in sound quality. 1Mii was terrible. Of the three I liked, they all had a slightly different character, but all were pretty good. I compared them to Fiio uBTR and BTR3K. The three good ones in this test were qualitatively equivalent to uBTR. None of them were as good as the BTR3K, which costs 4-5 times more than these. I noticed the difference in sound field (although my son couldn't see it - you may need a trained ear to tell it apart). Of the five on test, my favorite would have been the old Sonruu, but the jack was stiff. It's fine if you plug and unplug it, but if you plug and unplug it a lot it might not be great. The older Sonruu had a single clip and I loved it. He was also slightly taller than the others. Now for the newer Sonruu player model. I tried it out for just a few days after comparing all seven of the above devices. I only compared directly with the BTR3K. In short, the only thing I can do to reliably tell them apart in a blind test is listen to the noise floor. There is a *very* subtle noise when the amp is turned on before and after the music plays (the amp turns on milliseconds before the song starts and stays on for maybe a second after the song ends or is paused). In fact, almost no one will notice. Sonruu improved the jack and I'm happy with it. I checked that it has an auto shut off when nothing is plugged in. It's smaller than the old Sonruu receiver but doesn't have a clip. The operation of the buttons is a bit different than what I'm used to and takes some getting used to. All in all, if I had to buy a new Bluetooth receiver, I would buy this one. It's cheap, has decent build quality and most importantly (to me) it sounds great. Note that I haven't tested the battery life on any of them. If I find the battery life surprisingly good or bad on this device, I'll come back and update this review. cheap as they are and work just as well as they do. When I was a kid, we had to get up, go to the TV and turn the knob to change the channel (of which there were only a few). What will the next 50 years bring? Disclaimer: The manufacturer contacted me after I ordered their other device and offered to ship it to me for free in exchange for my honest review. This happened to me for the first time.
