Pretty good DAC with decent output power. You need apps like Hiby music (free), UAPP (Paid) to unlock the true potential of this DAC. Hardware volume can be increased to get decent power boost which you would otherwise lack. Drives all but the most power hungry IEMs AND many low impedance headphones. I was surprized how it handled my Hifiman HE4XX which are notoriously power hungry being a somewhat low impedance headphone (due to low sensitivity). Not many devices I own can get these puppies loud enough and this little dongle provided decent enough volume for easy and comfy listening. Although I would still say the low end would shine and scale with better amping.
It has a warmish decent sound, with clean upper end and decent mids, nothing to write home about. Soundstage is not that wide but still decent enough, imaging is pretty good at this price. Don't get me wrong, it is VERY good for the price you're paying. How much do you expect from a 700 taka DAC dongle anyway?
Better than your phone or laptop DAC unless you have TOTL laptop/ LG phones with Quad DAC.
Hope this helps!
