Powerful little DAC
I use this to drive my focal clear mg headphones. I have used 4 other dacs. This is the best. It’s got plenty of power, sound great and has a very wide soundstage. Love it!

It soothed my ears until it broke my heart
I loved this dongle amp/dac. It has a very clean and neutral presentation and I've driven a 64 Audio U4s IEM, a closed-back Focal Stellia, and an open-back Focal Utopia with this little thing. No problem with any of these and it's particularly good from it's balanced 4.4mm output. I'd also like to note that Questyle's usb-c to Lightning cable (unfortunately it needs to be purchased seperately) is one of only two brands of "short" dongle cables that I have not had issue with (even the high-end cable can exhibit too much wiggle in the Lightning port, causing the dac/amp to disconnect). However, I did have a problem. The M15i died on the 6th day. It simply would not connect or power on. Note that it was not due to a bad cable; I tried several others and none worked. That said, I love this dac/amp so much that rather than return for a refund, I requested a replacement. I'm hoping I will be able to return with a positive update, but for now I have to give this a low rating. UPDATE: The M15i mysteriously came back to life. Not sure if it suffered thermal shutdown (note that the case was cool when it died the previous day). Currently sounds great, but I'm still going to return this one when the replacement arrives as I fear this may happen again. Do note that I'm still going for a replacement rather than a refund because I love it that much. 2nd UPDATE: Replacement M15i arrived and it has been stable. Customer support was good, although replacement took longer than expected to arrive. I guess replacements do not qualify for Prime shipping; I should have returned for a refund and then bought a new one (that would still qualify for 2-day Prime shipping). Despite having run into a shutdown issue on the first unit, this is still currently my favorite dongle dac/amp. It gives me the mobility I want while using some high-end IEMs.
