A Pocket Overture

The Questyle M15 is a compact yet powerful mobile HiFi DAC and amplifier. It delivers a clean and transparent sound. It avoids coloration and distortion, allowing music to shine without interference. Compared to other dongle DACs which I own like the Monolith and Dragonfly, the M15 maintains its clarity and fidelity. The M15’s standout feature is its excellent instrument separation. Each instrument occupies its own space, creating a spacious and detailed soundstage. The M15 packs a punch whether you’re using sensitive or power-hungry over-ears, the M15 adapts effortlessly. The inclusion of a balanced 4.4mm TRRS output ensures compatibility with a wide range of headphones. I am thoroughly enjoying using it. Not just a DAC. Not merely an amp. It’s a whispered promise—a symphony in your pocket. 🌟🎵

Thank you for your glowing review of the Questyle M15 Portable DAC & Amp! We are thrilled to hear that you are enjoying the clean and transparent sound it provides, without any interference. We also appreciate your comparison to other dongle DACs and how the M15 maintains its clarity and fidelity. We are glad that it adapts effortlessly to different headphones and that you are thoroughly enjoying using it. Thank you for choosing The Audio Store!

Good things come in small packages

This amp dac is a mini power house. As mentioned by other reviewers, it can get really loud and can easily power 300 Ohms headphones like Sennheiser HD 650 and HD 600 etc.

Only nitpick would be the lack of custom EQ options, which are present in similar priced units like Lotoo Paw S2. However, just based on sound quality alone, it is indeed head and shoulders above the competition. It's battery consumption on my Samsung Galaxy S22 ultra is decent enough and doesn't seem to drain out battery. Overall, a worthy buy.

Thanks for the review! We're glad to hear that this little amp dac is a powerhouse, and the lack of EQ options is a minor quibble - in our opinion, the sound quality is worth the price. We hope you enjoy it!

Best portable dac

This is by far the best portable dac I’ve heard
In fact it sounds even better than the higher tier DAP
The sound is neutral, The treble is extended without being sharp or fatiguing
Needs some burn in initially to open up
