I initially bought these earbuds for use in my side job, as a server at a bowling alley- which admittedly is an odd profession. I needed earbuds specifically with a conversation passthrough function, as I needed to hear customers, and still block out the sounds of falling pins. These worked quite well! However, there are some hold-ups. Sound Quality: These sound about as nice as you'd expect. The high end is a bit quiet for my liking, and there's definitely a ton of bass. Not exactly amazing sound for the price, but definitely passable. I've tried switching between the inbuilt EQs, and a word of advice- don't. The default is the best sounding, and still sounds at most okay. Noise Cancellation/Auditory Awareness: This works quite well! The conversations around you are quite clear, and it's pretty good at toning out the background noise. The noise is still there, however. If you're looking for noise cancellation on the cheap, though, these will work. Battery Life/Charging: Oh. Boy. These earbuds last a VERY long time in my experience. The advertised battery life is 6 hours, but I've been able to consistently get around 7. The case also recharges them relatively quickly, but... The charging contacts are finnicky. I sometimes find myself having to reseat the earbuds before they'll start charging, which leads into my next part of the review. My Issues: There are a few issues I've run into, the worst being the left earbuds disconnects. Yes, it is an issue that is noticeable. This will happen to me every week or two, and I have to place both earbuds back into the case then remove them to get the buds to reconnect. It's very irksome, and the main reason for my 3 star review. I also have run into issues with the case's charging cable, which is integrated. It is WAY too short. I actually have an extension that I use to charge these. The only upside to a cable this short is that it reduces bulk in your pocket/bag/etc. I would much rather have a longer cable that I carry along with me. All in all, I would recommend looking elsewhere for earbuds, unless you need these for a niche purpose like mine, and are on a bit of a budget. There are earbuds out there that do everything these do, but better- that is, if you're willing to pay. The Sony WF1000-MX3 come to mind on the top end, and the Echo Buds from Amazon are actually quite a good pick.

Unlike other reviewers' comments, my earbuds were not charged upon arrival. Therefore, initial setup procedure didn't work as described in Quick Start Guide. The very 1st thing any cordless, battery-powered product instructions should mention is to charge the batteries - or check them (& how to do that). The Quick Start Guide is very poorly written & expects a mid to high level of experience using wireless earbuds. Eventually everything was figured everything out thru trial & error. VERY disappointed in sound quality. Have tried all 3 equalizer settings & not one is adequate. Bass Boost for music & Signature for calls seem to be best options. My $5-8 Samsung corded earbuds have much better sound quality & output volume & put these JBuds to shame. The cordless convenience is nice. The controls are adequate, but you better have a good memory to remember all of the functions. Charging case & overall quality is very good. Would have given a higher rating (4 or 5) but the poor sound quality is a major disappointment.
