Bluetooth V5.0 Output Audio Receiver, KINDRM Mini Wireless 3.5mm Jack Aux Adapter Portable for Headphones, Speakers, Car/Home Stereo System(Black)

For $8.99, I was looking at this purchase only as a test case to see how well everything connected etc. between my macbook pro and my Bose Wave CD player with no Bluetooth. I figured that once I knew that everything worked well, that I would invest in a more expensive receiver with better sound quality. But this one is doing the job very well, and I'm perfectly happy with the sound quality. I did some quick comparisons with this, plugging directly into the minijack, and I don't notice a huge difference. True audiophiles probably would, but a true audiophile wouldn't be using Bluetooth in the first place.The battery life is pretty good, although I usually have it plugged in. Even the latency isn't that bad when I'm watching youtube videos, etc., although I'm sure that the small lag would be more of an issue for gamers who would want things like an aptX codec in their receivers.All in all, I'm very pleasantly surprised with this and would recommend trying it before investing in a more expensive receiver.Quick addendum: sometimes when the unit is plugged into the USB power and has automatically powered itself down after some time, it's a bit glitchy to switch it back on. Simple fix though. Just unplug from USB power, switch it on, and plug it back in. Hope that's helpful.

I have this paired with my Macbook laptop and wired in to a set of old fashioned 4.1 speakers sitting across the room. The sound quality is fine. I do have to leave this plugged in to its mini-USB power source (the battery is tiny).The only issue is my Macbook occasionally disconnects from these. I don't know if that's my laptop's fault or if it's this unit's fault. It only happens when I have nothing playing at the moment (i.e. iTunes is paused), it never happens while I'm listening to music or watching something on youtube or whatever else. The built-in voice thingy announces "Disconnected!" when that happens. Then it either reconnects on its own (half of the time), I need to click on the bluetooth icon and force it to reconnect, or it doesn't reconnect and after a minute the unit turns itself off (after announcing "power OFF!" lol).Other than that, it works fine.

I work in a noisy environment. I need to protect my hearing, but I also like to listen to audiobooks and podcasts while doing long, repetitive tasks. I'd tried two other Bluetooth solutions before buying this item. The first, a set of Bluetooth earbuds, worked great for a few months, then suddenly refused to connect. I went through the whole pairing procedure several times, with no success. At $90, they were rather expensive to last such a short time.Next I tried earbuds (https://www.amazon.com/ISOtunes-Headphones-Cancelling-Waterproof-Ultra-Durable/dp/B07789XNCV/ref=cm_cr_arp_d_product_top?ie=UTF8) which I highly recommend, and a separate Bluetooth receiver. The earbuds worked great, but the receiver died in one month!I replaced it with this receiver. I keep my phone on a charger on my workbench, and clip this receiver to my shirt pocket. It has substantially greater range than the other two receivers. Battery life is somewhat less, but at this low price, it was no problem to buy a second receiver, so I always have one charging while I listen to the other.Six months later, it's still going strong.

Though I never expect many performance features when an item like this is priced so low but I figured at this price I could buy several different bluetooth transmitter / receivers to determine which is best long term. At first this unit actually performed quite well. Solid bluetooth communication. Louder than most others with respect to output listening volume. And solid buttons that won't respond to light accidental pressings. However, I also like to test and see if units like this can function if also plugged-into the USB for full-time power during play. And that's where this thing now only failed, it's now stuck in a loop where I cannot even power the thing off. Nothing I try works to power this unit off and until it does, I'll have no idea whether or not I'm going to be able to re-establish connection to my phone. And I'm not going to wait to find out because another unit (see my other reviews if you care to find it) for only $11 blew this device out of the water with its out-of-the-box performance. So, nawww. It had a lot of promise for such a small device with a built-in clip. But no cigar.

it works - but the sound quality isn't great - it is nice and small however and it does work

Audio quality is not HiFi but good enough.

Works perfect for my Harley. Radio originally has to hooked through the jack but with this I can run it with Bluetooth. Easy to connect and no distortion

This worked great for 8 months and now won't take a charge. It is useless now. Also there are very bright lights that blink the whole time it is in use. This is annoying if you are trying to use it where you are sleeping.
