Smart Audio Doesn’t Cut It Anymore
People listen to music pretty much everywhere they go. And the medium for listening to that music is usually a cellphone. It’s great for carrying music around, but the audio tech isn’t going to match that of a home system because there’s so many other things going on in that phone that there’s only so much “room” for the digital audio converter system. That’s where the QUESTYLE M15 ULTRA PORTABLE USB DAC/AMPLIFIER comes in.

Built For Listening
The M15’s purpose is to improve upon the sound flowing from the audio source (being the smartphone for the most part) and into the headphones/earbuds of the user. It uses a 3.5mm input port and dual 3.5mm single ended and 4.4mm balanced output so one end goes to the headphones/earbuds, with the other end receiving the audio from the audio source’s output (in the case of a non 3.5mm available iPhone, it’s either an adapter or no-go).
So that’s pretty much the physical end of things that are “user serviceable,” with a lot of tech packed into the small metal candy bar-like chassis, such as a high-end 32 bit DAC chip and output power that can handle real headphones. High rez PCM, DSD and MQA support of course, and high and low gain support for low and high powered headphones. And seeing the two LED lights is pretty easy because one side is clear for looking at the bits just mentioned as well as the rest of the circuitry. And if you wonder if the sound is improved when using it, for sure it is (just don’t use those low-rez audio files, ok?).

The QUESTYLE M15 ULTRA PORTABLE USB DAC/AMPLIFIER has a USB-C connector and fairly long battery life. It is a well-crafted piece of portable DAC tech whose presence is far from onerous,
and whose performance is right up there with a home amplifier. Which means you can use it with your laptop or desktop just as nicely.
