I haven't had it long, but I had to write this. It's funny reading reviews of people complaining about not charging, no charge light, no clear instructions, the cable being an issue, it's all bull. The instructions are very clear, and in several languages. The cable is a standard USB C to A plug. The case charged fine, and I love this, I connected it to my phone, and charged the Earbuds in the case, and I even got a notification on my phone when they were charged 100%. I thought I even had them turned off, but these must be the smartest accessory I've ever gotten. The company uses the latest Bluetooth version for the best energy efficiency, so they don't waste a ton of power or battery life by just being on, you have to actively be using them.I'll be glad to update my review later on when I've had more time with them. For now, I'm simply amazed.Update after a bit of testing and experimenting. Turns out, sadly, these are not HD Earbuds. I love Bluedio since I got the UFO (U) with PPS8, and those are incredible. These Earbuds however, I'm offended that they are described as HD Audio, when in fact, they only use the lowest quality format to reproduce sound.A quick lesson on audio quality. There's a lot that's up to personal preference, but the mathematical details can't be argued. Put simply, bit depth and sample rate are similar to display resolution and frame rate. The higher the bit depth, the more accurately the audio sample can represent a change in the soundwave, like the different between an 8 bit picture, and a 32 bit picture, or think of how 8 bit sounds were like decades ago compared to now. The sample rate being 44.1, 48, 92khz, and such, this is similar to frame rate. Imagine watching high speed video at 20fps, as apposed to 60fps, or higher, though some may not notice the difference over 40fps. The fact is, the finer the details, the more is lost when it's not reproduced properly, doesn't matter who you are, or what you like.All that being said, I'm offended by this product. The Bluetooth codec they use is the most standard required codec for any Bluetooth device using A2DP, this codec being SBC, and even though this codec is capable of higher functioning, the Earbuds are limited to 16 bit by 44.1 khz. Not even a decent 24 bit by 48 khz, which I'd consider basic higher quality. I included pictures, showing my phone trying to play at 24 bit 92 khz, and the device still scales down to the lowest setting. The worst part is, there's several codec options that work better, and some are even completely free because they're part of Android's open source project. LDAC by Sony is such a codec, pushing the playback quality of Bluetooth as far as possible, with both consistency and quality in mind, it can do 16 bit by 44.1 khz, and up to 36bit by 92khz, with very little to now lag, or delay, which brings up another issue. The Earbuds have a timelag of 0.4 seconds, which isn't an issue for purely music listening, but any media that involves video, or immediate audio feedback gets ruined by it.All this being said, for $20 bucks, I'm not really complaining, only stating facts, and misrepresentation. For the money, these Earbuds are absolutely worth it. Phone calls are nice, and music sounds amazing for what it is capable of. The bass is deep, and impressive, though like any small speakers, you'll never feel it like with full headsets. Still, love the sound, and they stay plugged in very well, while being very comfortable, almost to the point I forget they're there. They block out nearly all sound, unless you have the volume very low or off, in fact, they made me feel like I wouldn't hear a gunshot, or even a train right next to me. Word of advice, don't wear anywhere that you need to stay alert.One last note, the Earbuds have a habit of turning themselves back on, even when still in the case once they're done charging. I would have liked a function that keeps them off, at least until I open the case, though on the plus side, they auto connect, and will let your phone know they're fully charged, and ready to go. The "Face Detection", is really just an iffy proximity sensor on the right earpiece. I've had it cut off my music because I was only adjusting it in my ear, and then I had to hit play, and I've had it start my music in my hand just because I held it a certain way, as well as continuing to play music in the case. It's a good idea, but doesn't always function when it should, and does a lot when it shouldn't.I'll finish this review by saying that I got these earphones for about $20 bucks. I would have given them a five star rating, and a perfect review, and believe me, I wanted to, but I can't ignore that the company brags about quality that just isn't there. They sound great, don't get me wrong, but they're nowhere near HD, that's a mathematical fact, not an opinion. I hope the company reads this review, and takes it to heart, cause I'm a fan, and a supporter, I brag to everyone about my 3 year old UFO Headset, and this just disappointed me. I truly hope they fix this, and do it right, but in the meantime, I will say it one more time, for $20 bucks, you're getting your money's worth, perhaps more, but just not as much as promised.
