Mad Channel Isolation, OP Amp is the hero here
I have DACs, this is my 5th or 6th.. I am the guy who will spend equivalent of a car if I can get impressive audio. This one is essentially to be used with open back full size cans.. Nothing else would suffice. If you want the best quality Open back is the way to go. I don't care about the gaming mic, I have a Snowball & a Razer Megalodon which still works and it kicks butt. If you want something for an iem just look else where. Pros: - Solid hardware and components, you can hear the relay switch.. so that's quality - Wide Soundstage af, I am yet to listen to something close - Pair it with higher impedance headphones and please try a lossless audio source - Punches way above it's price tag - THD & SNR -- below average performance, it's lacking - That SNR issue disappears once you have a linear dc source (no SMPS) - Music made by actual musicians with actual instruments playing shine through and in detail The first track I threw at it was "Hai Rama" Rangeela - A.R. Rahman - this man always keeps dynamic range on point - Mad stereo separation you have to listen to it - Bass & Treble knobs actually are usable, lately everything has just destroyed it Cons: - If you listen to commercial music made exclusively by software, this DAC is trash - Extremely articulated clarity which is too rich, use the treble knob to fix - I have warmer sounding DACs like the Fiio Q1, Sony NW-55, Everything including an M2 Macbook Pro but cables all way no wireless - If you listen to the top 10 tracks all the time, this is not going to help - It comes with a SPDIF cable and I guess it's okay in a pinch but the quality is rubbish The Grey Area: - Nothing is permanent unless it is missing inbuilt batteries - This can be power from some phones (my ROG 3 can drive it for about 2.5 hrs easily) - Bass extension is too crisp for my taste, nothing against it - No way I would leave this at home; my wife has listened to it, she will take it away.. She took my FiiO BTR 3 also.. - If you own a Sennheiser or DT990 etc.. this is a perfect fit and something that can be enjoyable for a long time

Affordable Audio Enhancement: A Non-Audiophile's Perspective
This is undeniably an affordable option to significantly enhance your music listening experience. It provides a better soundstage, smooth and non-fatiguing audio quality, and performs well with most music genres. It's compatible with laptops, PCs, and Jio Set-Top boxes but unfortunately does not work with at least Samsung mobile phones. Priced at just INR 5,000, there may be few comparable alternatives. Please note that I am not an audiophile, but I have enjoyed high-quality music for over a decade on a budget. As for the warranty, there is a claim of an 18-month product warranty with repair options thereafter. Only time will tell how well they honor those claims.

Good for gaming in windows.
The price is reasonable for the quality.It serves well for gaming.I mostly play Call of Duty and Apex.In Call of Duty,directional audio is pretty good,but you need to turn on the loudness equalization in the audio settings of windows .It works well with all headphones.But with iems ,you might hear a slight buzz in high gain.While gaming,this is not noticeable much.

No Regrets atall.
I made the best choice and as I mentioned earlier no Regrets at all. The sound, ease of using the product ,Quality of the product , I can go on for the kind of experience Im enjoying .It was all worth my Time and money. One can only experience as its difficult to explain in words. All I would want to say is THANKYOU. I'm busy and enjoying with all my Audiophile files. Only think I would like to add is buy a separate Y splitter to 3.5mm balanced unit as that is not upto the mark. I bought it a new one from Amazon . There is no more distortions. Give it a try because Heaven is on Earth.

Important For gaming consoles
Gaming console when I purchase an Xbox series X and a PlayStation 5 Pro, I felt that when I attached or connected to my monitor which I use it mostly for my PC. Sound editing and image editing works. When I try to connect for the first time I saw that there was no sound coming so I got a HDMI extractor and I got this product and the functionality. The compactness the quality, the connectivity, the compatibility and mainly the sound quality of of each dynamic response is so good while playing games. You can adjust your required or desired tones through this and it has a very good amp and this is must for a gamer who is using with especially using monitor rather than a TV
