I had one requirement when buying earbuds. Long battery life. Every brand says “48 hours” but they mean 6 hours with 8 charges. Not with these and I’m super happy about that.I work in a data center environment. Noise levels are a consistent 90+db and I love my music. I hate stopping to charge.My coworker bought a pair first and after debating, I pulled the trigger and I’m glad I did!First off, the battery. 12 hours easy on the bud charge with several days worth in the case. I have zero complaints on battery life.The case: the case is nicely built. I find myself fidgeting with the lid and it hasn’t broken yet.USB-C charging is something that is wonderful to see as it’s becoming the norm.I had originally thought the flashlight would be a gimmick, but I use it a lot. In a data center environment it’s nice to have a bright light handy for the dark server crevices.The earbuds themselves. The noise cancellation is top notch because it’s passive rather than active (also helps the battery life. ANC is a power vampire). If I don’t want to listen to music, they function as earplugs, albeit a bit bulky compared to foam ones. The several included tips made customizing to my fit easy as well as the in-ear hooks. They don’t fall out, they don’t feel loose.They can be used as a pair or on their own which is a nice touch, even if it makes me look a little pretentious.Sound quality is excellent. It’s not 7:1 by any means but I can hear my music, it isn’t muffled or muddled by overzealous bass. They did well.As noted in other reviews, there is no volume adjustment. I use my Apple Watch to adjust volume. It’s really not a deal breaker. Considering they’re earplugs, you don’t have to adjust the volume much anyways because the noise outside stays constantly quiet.I also use them when cleaning. It’s wonderful to be able to vacuum and hear my music without turning it up to 112%.Now for the downsides. All of which I don’t deduct stars because I (somewhat) expected it.Pairing issues. Every now and then when removing them from the case they don’t auto pair. Putting it back in the case and removing again allows it to power cycle and connect. Usually one time does it. Most I ever had to do was 6 times. Annoying, but manageable.On the note of pairing issues, usually when paused, one will drop. Usually the right earbud, but sometimes the left side. It will reconnect on its own but it’s jarring to be in silence when talkin to a coworker and hear “PAIRING”. It’s got me good a few times. Since it pairs itself again, I don’t mind.I know pairing issues tend to arise with wireless buds as one tends to be the “relay”. I’m honestly not hard to please so this doesn’t bug me but it may bug you.Overall, this is one of the best purchases I’ve made. It’s improved my quality of life at work and meets their NRR -25db requirement for earpro. I got them on sale. If they’re on sale for you, grab a pair. Even at full price, they’re well worth it.PS. Elgin also makes over-ear versions if in-ear isn’t your style.
