Review: Not Bad IEM BT Ear Hook Adapters - First off, dang the charging case if huge! I've gotten the MMCX version instead of the 2 pin just because I have an MMCX to 2 pin adapters and some people claim that the 2 pin version is not up to standard... I use these with the Zero:Blue2 iem and, for what it is, is a nice addition for anyone who wants to turn their wired iems to earpods. The sound quality of these aren't the best but, depending on your iem, with the zero:blue2 it does retain the bass. However the sound seems more quiet compared to if you use a wire cable. The ear hooks fits comfortably around the ears and with the adapters making it a bit longer, is still comfortable to wear. Going to far away from the connected DAP or device will cause the bluetooth connectivity to fluctuate and in and out trying to stay connected. Making the music fade in and out with both earpiece. There are alot of these bluetooth hook adapters for iem that ranges from 29 usd (maybe 25 usd at the least) to over 100+ usd (Fiio) out there. These ones I like for its price range and the fact I took a dive with tis one instead of the others! Just make sure to remove the plastic film from behind to ear hooks in order to charge them.
Review: Go wireless with your MMCX IEMs! - Very light, and for the hour (or so) I've been using them, they seem very comfortable (I barely feel them at all). As you can see in the attached photos, I wear glasses, and the BT adapters don't press the arms into my head, which was something I was nervous about (I really didn't want to have to return these in that case). I had zero issue getting these paired to my phone - As soon as I long-pressed the button on one of them, they showed up in my phone "Connected Devices" list, and paired without issue. I'm happy that the BT adapters, IEMs, and the foam tips all fit into the case -- every pair of ear buds I've had over the years could not fit the foam tips I use into their cases. Having to remove them, and keep them in a separate case (that I'd have to carry in addition to the IEMs/buds themselves) wasn't something I looked forward to, and caused extra wear to the tips. Only complaint I've got is that, without EQ on my BASN BSG-MC100 IEMs, the audio is very mid-bass heavy, nearly no treble - something that's pretty easily fixed. I can't speak to 'value for money', as I've only had them in my hands for a day, but so far things look pretty positive in that department.

### ⭐⭐⭐⭐⭐ Greatly Exceeded my Expectations
*by B***G on October 3, 2025*

So I have wanted to write a review for a while but wanted to put a few months of use on these first, because in my experience, chinese audio products work great until they die. So a few months in, what is my experience? These things are great, and far exceed my expectations. Battery Life - I have literally listened to these at work all day from 9am to 7pm and didn’t have to charge them. This has been the case multiple times. The battery life is insane, with the case charging I would bet you would get like 40 hours of listening, I seriously don’t get it, nothing else I have used comes close. - Fit - For me they fit great and stay in place, I dont feel them hanging on my ear and suffer zero ear fatigue. Every once in a while the adapter will come off of the inear and ill have to put it back on but that has happened probably 3 times. But everyones ears are different so I’m sure some people may hate it, while others may love it like me. Ease of use - it paired quickly, charges easily, and automatically connects and disconnects with one or both or going from both down to one. I really haven’t had a single problem with the automatic pairing and disconnecting. Once in a while, (two times so far and only while driving) it will like stutter between the headsets, I assume I am passing through a high interference area, and then it’ll automatically fix itself with a button press or just waiting a few seconds. -sound quality- I am no audiophile, my destroyed ears won’t allow that. But I do dabble. I will say this; it is pretty difficult to tell the difference between my 7hz Timeless hard wired into my Schiit Audio DAC/AMP and my 7hz Timeless connected to these. Are there subtle differences? I dunno, maybe? But would I tell those differences while on a roof or driving or working on a unit? Not likely. Now compare that to my Audio Technica M50xBT, the difference between bluetooth and wired is night and day. So I don’t know if I got a magic pair, or if others experienced the same thing as me, but I am quite impressed with this. The case is big, thats really the only downside, not only is it big but its hollowness makes it seem like it could easily be smaller. But since so far my battery life is more than a day on a single charge, it hasn’t been much of an issue, but its an area of improvement. If you have mmcx in ears, and you want to go bluetooth with them, I 100% endorse these guys and hope they keep making them for a long time. Great job making this product guys.
