Its portable, plug-and-play design makes it perfect for use with smartphones, laptops, and other devices, offering studio-quality sound for audiophiles and casual listeners alike.

At first I thought this distorted the sound on my Dusk but then I realized that you need to be very careful basically half of the volume on my mobile phone was like more than enough amplification. Compared to my Dawn Pro I have to say it isn't going to blow you out of the water and this will really come down to durability since my Dawn Pro had problems with the stock cable it came with and also I just needed a reliable dongle dac without the block element if it can do that great.
I always thought my headphones were quite bassy, just thinking I should buy ones with a different tuning but decided to try a separate DAC/AMP first. They removed the ‘over bass’ sound completely. This thing probably won’t beat any records, but wow did they ever improve the sound quality of my headphones compared to direct PC!!
Product exceeds performance expectations.
Delivery was quick and incident-free.
Sounds good when using the right apps and equipment
Plug and play beast. Absolutely smashes apple dongle in every way. My default recommendation for a DAC for iems and headphones. Using at up to 1/4th volume (when I want it loud) with Kiwiears KE4. Beautiful, clean power.
I have noticed that when mobile reception is very poor to failing (I live in new Zealand, so this is a frequent occurrence when traveling through ranges and gorges), some data transfer sounds can be audible when there is no music playing, or the song is exceptionally quiet. Not an issue when reception is good+
