## Description

Product description

Review: Great bluetooth headphone adapters! HD Audio latency is kind of bad, but you can fix that. - I'll give you a quick TLDR: They are good, buy them. They have latency on HD audio which sucks for watching video, but if you turn of HD audio they still sound great and the latency goes away. The rest of this is specifics about the the audio. Honestly, these sound amazing and I don't really feel the lack of lossless audio. The AAC audio is very high definition and it doesn't really sound different than one of my bluetooth DACs with lossless paired with the same iems. It seems that the digital amplification circuitry is very good a similar to a proper dac. No "hiss" at low audio levels and no crunchy fade in's from silence to audio. Reading some of the other reviews people have mentioned that the pairing audio is super loud. I would agree with that, but in my case I never ran into disconnections so I never deal with it. I think if you also experience solid connectivity that shouldn't be a problem, but your success will vary. I will say that I am really please with how stable the connection is as a huge guy. This is going to sound dumb, but I'm used to headphones cutting out if they don't have really good bluetooth because bluetooth signal has a hard time transmitting through flesh. Being 6'5 and 350lbs, I'd say 1 out of 4 bluetooth headphones I use cut out randomly at times because of this issue. These didn't have that issue with either headphone. One tip I will give people with these is that, if you are dealing with serious latency while using them to watch things like youtube, it seems like these headphones are slow on the decoding of the HD Audio. They sound genuinely fine even without HD audio on, so if you are using them with Youtube a lot you might turn off HD audio. Oh, and the case is 10/10. Seriously, I have a case for my IEM's and it's fairly compact, but given the nature of the IEM's I use the most, they are just chonky. It's hard to make anything that isn't thick that can safely store them. This has just enough room and the rounded edges makes it about comfortable as a case for these IEM's can be. It makes me want to 3d print a similar case, but with a little extra room for a cable.
Review: Great product, great price, stays put in your ear and has great sound! - Another great purchase to write about! I work around our property every weekend and being a music lover I always have ear buds in so I can listen to tunes while I work. The problem is apparently my ears are misshapen in some way that makes every ear bud I've tried not seat correctly so the buds fall out of my ear. Anyone who constantly has to readjust or push their earbuds in can feel me on that point. I wanted a quality ear bud that fit securely and wouldn't come loose as I worked - and this product didn't disappoint. I will say that being Chinese made, it has some funny quirks - it sounds like the lady announcing that the device has connected says "Connectate" instead of "Connected". I don't really care about that though - all I care is that the sound is good quality and the buds stay firmly in my ear. This product did both very well and I'm loving not having to take my buds out and reseat them every 5 mins. I'm using a after product foam type ear piece - you can squish it down tight, put it in your ear, and it will expand to fit perfectly. Battery life has been great for the time I've had these (about 6 months). I'll work around our 7 acre property for 6-7 hours without having to charge and it still has juice left if I forget to charge them. This also has an option to be used as a corded ear bud as well, which I did find useful since I travel a lot and use headphones with a plug while flying to watch movies or listen to music. Now I have the best of both worlds. From a cost/value perspective you can't beat the price and they do seem to be of good quality. I would recommend this to anyone looking for a versatile set of music buds, that stay put in your ear and block out unwanted noise, keep their charge for 7+ hours, and are easy to pair to your phone/tablet or computer. I'd definitely buy them again.

### ⭐⭐⭐⭐ Really handy case.
*by B***N on June 8, 2025*

I still have the set and charging case and it still works fine. Best pair of earphones I've ever had before. Sound is great as long as they are fitted in your ear correctly. I use them when I mow the yard mainly, that's how good they are. Though they will slip loose and let sound in as I get sweat on my head. They don't last all day on a single charge either but they can go for a couple of hours before needing to be put back in the charge case if your using the BT mode. I also have the wires so I don't have to use the Bluetooth/Battery adapters unless I want to. The units pair with any Bluetooth device, so I can use them with my phone, or either of my computers easily. I got the earphones with wires for $20 and the BT and battery for $30 so a little over 50 dollars for all the components. Considering how expensive name brand versions of these things are I feel like these were priced fairly and was a good deal. Thanks
