Review: This actually works!! - For me it was a nervous move to order this. I would've returned it if it had no value. But trust me, it works, and it has actual value. The audio it helps my 5-year-old earphones play is beyond my expectations. It is not just the loudness or the clarity. It's the shape of audio that you get with this DAC. The whole mood is changed, it makes Bright music brighter and mellow music darker. I never knew I was missing so many details in a song using my wireless earphones. Sad to say even my laptop does not have good DAC preinstalled. This completes it. Gives more power to earphones to do more in detail. The built is awesome and pure sturdy. Made of metal and premium material which is to be expected with this price. Is it worth the price? Yes, there is a free case and a small USB C to USB A converter too. I recommend it totally. On the phone as well as the laptop it works its magic. Pair it with good equalizer and you are good to go. For IEMs it's a must. Though this is my first purchase in the audiophile niece. Will update later when I get my hands on the IEMs.
Review: Good but pricey - Overall a good product. Price is a high as a Chinese product. Review after a month is good.

### ⭐⭐⭐⭐ Good but pricey
*by B***A on 18 June 2025*

Overall a good product. Price is a high as a Chinese product. Review after a month is good.

### ⭐⭐⭐⭐⭐ Instant improvement in sound quality
*by D***R on 22 January 2025*

Awesome product, unleashes the full potential of your IEMs and the amp improves it. A pro tip: Get a good iem set it up with this bad boy and listen to 32bit/198khz audio files, you'll rethink everything you've ever heard. Anyways the product is best for its price. Recommended getting a DAC if you have IEMs it's a must. Soo worth it.
