While this bluetooth conversion kit is very cheap, and actually has amazing sound quality too, it has some glaring faults that cause me to be unable to recommend it.From first use, these have just been far too loud. Even at the lowest setting on my iPhone, these are near ear-splittingly loud in a quiet room. While they are great to listen to at volume 1-3 (max is ~16) if I really want to rock out to loud music, there is no ability to just chill out and listen to some quiet tunes with these.While the volume issue was annoying, I would've still considered these potentially worthy of 5 stars. After all, the form factor is best for active pursuits like the gym where loud music is not an issue anyways, so perhaps they'd be the perfect headphone for a niche application; just not a "do everything all the time" headphone set, which is fine.However, as of last week (under two months since delivery), the left channel on these headphones has had awful crackling and popping that has only worsened. In their current state, they are unusable. I can simply not recommend headphones that will last less than 2 months and a total of ~5 charges before dying.Also a note for the manufacturer on the subject of charging: The charging port cover, made of hard plastic, is very annoying to get off. Please replace with a rubber cover with a tab that makes it easier to expose the charging port.

Good price for what it is, not too long so it doesn't stick to the top of my back

Sometimes, you just want to go wireless, and while there are some better options out there, this is a very budget friendly option that is easy to set up and use.Any 2 pin IEMs will work with these, so long as they don't need too much juice to drive.Volume and battery life is pretty good, lasts a full day on one charge no problem, which is really nice.They charge pretty quickly.Connectivity and sound is all fine, getting them connected took a little bit of trial and error but once paired they connect very quickly.All in all, I am pretty happy with these.Paired them with some KZ IEMs and they run great.

Finally a product that stays put in the ear pods. Another brand's wires were too thin and they kept coming out.This product ROCKS.. Can be bluetoothed with both iPhone and iMac at same time. Audio and connectivity is flawless. Highly recommend these for old monitor mixers who want to use their High End Ear Buds for music away from the mixing board.Thanks KBEAR! Will be a happy camper for some time with these....

I got this 0.78 2 pin Bluetooth adapter to use with the 7Hz x Crinacle Salnotes Dioko IEM set. It is working great! The sound quality is still there thanks to the Dioko IEMs and now I don't have to worry about them getting yanked from my ears when I move. So good!

I ordered these because I wanted a bluetooth option for using IEMs that I can easily wear around my neck when not in use. What I got was a very low quality product that broke within less than a week of light use.Immediately the problem I faced using these was that they played music far too loudly. On my iPhone 14 I kept the volume down to the lowest setting most of the time. Anything louder than 1 or 2 from the lowest setting would be too loud and would distort the audio in an ugly way. (EDIT: To add to my frustration, when my original review mentioned this sent me instructions on how to turn the volume down on my phone)Then a couple days of wearing them around the house the left side just stopped working. The IEMs were stilll functional with other accessories but not these. A terrible product all the way through.

So far, so good. Guessing red dot on the ear hook is RIGHT, and blue dot on the other is LEFT. This adapter DOES WORK with my MOONDROP CHU 2 IEMs--which is the main piece of information I was looking for here. Seem less durable than I'd hoped, but a good deal for the price point.

I'm honestly pleasantly surprised by how well this works for a Bluetooth IEM adapter that's under $20 — but there's one important caveat for anyone who requires high-definition codec support.First, the positives:- On the standard 2-pin model, the connectors are small enough to fit into IEMs with a recessed jack such as the Truthear Hola.- Surprisingly for a sub-$20 adapter, this supports multipoint pairing! Pair with one device, disconnect, then pair with another device, and it will connect to both the next time you turn it on.- The microphone is decently audible unlike some other adapters I've tested, and supports 16KHz mSBC voice codec.- 50% volume is more than sufficiently loud on the Truthear Hola and Salnotes Zero, so this should be able to drive IEMs that require more power.- The charging port is USB-C, not Micro-USB.On the middling side, the battery life is basically what's advertised - it seems to get around 6 hours of constant playback before I start getting "low battery" warnings. Still a decent amount of time, except for one frustrating annoyance.And finally, a few frustrations:- Playing and charging at the same time is not supported. Plugging in a USB power source immediately drops the Bluetooth connection, and while it's plugged in, holding the center button to turn it on does nothing.- Despite what the packaging and Amazon listing claim, I could only get this to use the SBC codec, and not AAC. I've tested using both a Pixel 6a and an M1 MacBook, and both show the codec as being SBC, with no option to enable HD audio in developer options on the former. Judging from the console logs on my Mac, It does at least use the high-quality (328 Kbps) SBC profile, so sound quality is still decent; still, if you specifically need AAC support, it may be worth looking at other adapters instead.- The instructions are extremely minimal and don't even identify how to perform a factory reset in case of connection difficulty. (Although it's undocumented, this feature *does* exist, and I discovered it completely by accident: hold the plus and minus buttons until you hear a "disconnected" prompt, at which point all pairing records will be cleared.)
