SMSL D10 - USB Headphone Amp and DAC

This is an excellent dongle DAC. Despite its small size, power output is very impressive and was able to drive just about any headphone or IEM I tested. Both 3.5 and balanced outputs are available, a big plus in my opinion. The device is easily portable, and works fine with multiple sources I tried - smartphones, tablets, PCs all had no issue. A USB-C to USB-C cable is provided, you’ll need a USB-C to A if you only have USB-A ports. There’s no gain control, just volume - which may be disappointing to some but I didn’t really find this to be a problem considering its intended use.

As I’ve said, power output is impressive - I never felt like I couldn’t get sufficient volume out of my gear. Sound quality is also very pleasing. I find the DAC leans a tad bit warm in terms of sound profile, not something I can be certain of but overall I found it to be a rather neutral presentation. Treble might feel a bit smooth on certain gear, but never harsh. I prefer it that way.

Now, obviously this isn’t going to give you the output of larger desktop DACs - but considering its size and portability, still impressive. I was able to crank it to hearing-loss levels. Even on a smartphone, I never needed to really push the volume much. On some gear, pushing the volume too high did expose some harshness in mids and treble that higher end DACs handle fine. I can’t imagine anyone really doing that to their ears though.

For those looking for a step up from regular dongles, the D10 is a great choice. I can’t compare it to many other similarly priced dongles, but it’s definitely good value for those looking for a little more without having to use a hefty device. Lack of gain control may be a con, but looking at the intended use of the device as a dongle, I won’t knock it. Some will find it a bit pricey considering its size. As someone looking to get a bit more kick out of my IEM or headphones while on the move, I find it good value.
