Review: Good product would recommend - Case is a little bulky in the pocket but accommodates very large iems so I suppose thats fair enough. The largest I have are the Mangrid Tea2s and those were no problem, although I have them connected to Moondrop Lan's for regular use. Battery life is good and I only charge the case once or twice a week right now, and their energy saving mode while not playing anything is great! I've fallen asleep without putting them in the case only to find them at 5% less battery than they were the night before. Bluetooth startup sounds are thankfully not deafeningly loud and are pretty close to my regular listening levels. Maximum volume might be a touch low if your iems are less sensitive but I am very comfortable listening at 65% volume or less. Sound quality is good, more than reasonable for the price. I've been using AAC and noticed no noise floor or artifacts, although there might be a touch of distortion if you're driving these at max output. Haven't tested the mic quality myself but haven't gotten any complaints about it either
Review: fantastic battery life - I use these at work to listen to audio books and they last a full 10 hour day of constant sound near max volume with battery to spare! I compared them with my earbuds wired running off an atom amp listening to 320kbps music and i couldn't hear much of a difference. Only downside is limited codec choice and high latency. P.s. the 0.78 model came with the 2 pin connector that fits into a little square hole on the earbud

### ⭐⭐⭐ Good sound but QC needs improvement
*by B***R on April 11, 2026*

I enjoyed these while they worked. Unfortunately after a few days one of the sides became very quiet, rendering them unusable. Clean connectors and the IEMs work fine wired, so I know it was the adapter. Open to advice on how to fix
