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

situation : malentendant, j'ai un casque filaire MEZE 105 Silva, avec un cordon DAC qui me permet, en le branchant sur le téléphone d'avoir une écoute améliorée en liaison avec le logiciel "amplification" d'Android. Mais pour la TV, c'est plutôt plus compliqué. TV SAMSUNG 65 TQ65S95D avec platine extérieure et ses connexions. J'ai commencé avec un SENNHEISER RS195, bon casque, connexion optique, mais le volume son est limité. Il me fallait donc une solution pour brancher la sortie optique de la TV sur un ampli DAC avec réglages séparés (aigus, basses, volume) sur lequel, je brancherai mon filaire. J'ai donc soumis chatgpt 5.2 à la question et après un prompt indiquant qu'il était important que je puisse entendre les voix correctement (problème de phonèmes), il m'a proposé 3 articles possibles, en me donnant un avis : sur l'utilisation réelle, la puissance, le rapport/qualité prix et ce modèle est sorti en 1er de son classement. J'ai donc essayé et le résultat est parfait. Je peux ainsi choisir en même temps l'utilisation du casque en vue : - d'obtenir le son du HP TV si une personne regarde une émission avec moi - idem pour le son de la barre de son SENNHEISER notamment pour le Dolby ATMOS (le Fosi ne prend en charge que le PCM sinon, ça ne fonctionne pas) ou le casque seul en optique. Ainsi, je maîtrise les réglages. Le FOSI est petit, il a des connexions en câble optique, en RCA et en coaxial. L'alimentation se fait par USB C 5V (ce qui correspond à la norme standard) Une seule réserve : les boutons de réglage me paraissent "fragiles". A voir dans le temps. Attention, on trouve ce matériel un peu à tous les prix ça va de 65 € environ à 145 euros, mais j'ai préféré choisir le fabricant plutôt qu'un illustre inconnu en terme de fournisseur. Rapport qualité/prix : bon Note globale : 9/10 - je recommande selon usage et déplacements

🎧 Fosi Audio K5 PRO DAC/ヘッドホンアンプ レビュー オーディオ機器を揃え始めた中で、 DACやヘッドホンアンプという存在を知り、興味を持って初めて購入した一台です。 価格が手頃で手に取りやすかったのが購入の決め手でした。 【デザイン・外観】 シルバー基調のデザインで、デスク上に置くとしっかり映えます。 ノブ部分も金属感と光沢があり、価格以上に所有欲を満たしてくれる質感です。 Mac製品とも相性が良く、デスク環境に自然に馴染む点も好印象でした。 【使い勝手・接続】 操作はとてもシンプルで、初心者にも分かりやすい構成です。 Type-C接続に対応しているため扱いやすく、 iPadやPCに接続して使用していますが、特に迷うことなく使えています。 【音質・調整機能】 低音域・中高音域を個別に調整できるため、自分好みの音に仕上げやすいです。 ノブを回すだけで直感的に調整でき、ちょうど良いポイントで止めやすいのも便利でした。 出力はしっかりありますが、 イヤホン接続+大音量設定ではホワイトノイズが出ることがありました。 そのため、イヤホンよりもヘッドホンとの組み合わせの方が向いていると感じます。 【まとめ】 この価格帯でここまで満足できるのは素直にすごいと思います。 ✔︎ 初めてDAC/ヘッドホンアンプを導入する方 ✔︎ デスク周りを手軽に音質アップしたい方 ✔︎ 操作が簡単な機器を求めている方 には特におすすめです。 迷ったらまずこれを選んでみて良い一台だと思います。

This thing is amazing. It's a DAC/AMP all in one. It's sleek, feels very well made, and the audio coming out of it is amazing for my new FiiO FT1's I'm using. I've paired the FiiO FT1's with a ModMic 3.5mm version. I thought the headphones at first were really, really nice. Massive upgrade in sound quality from the Steel Series Arctis 7 Wireless. But I was experiencing a volume limit with my mobo powering the FT1's. When I plugged in the amp for the first time --- which is SUPER easy if your PC has a USB-C port. All power/audio goes through the USB-C port, so from the backside, all you need to plug in is the Fosi Audio DAC/AMP USB-C into amp, then into your PC. No drivers are needed, it's literally plug and play. Man-oh-man, when I powered it on for the first time it was like experiencing nothing I've ever experienced in life before. It's made me an audiophile of sorts now. I can never go back. The sound quality paired with the FiiO FT1's is incredible. The fact you can change bass/treb on the fly is amazing. I would've loved one more knob for mids, but honestly, the knobs are very well built. The Bass/Treb have a detent in the middle, so if you are in low light, it's very easy to find where you are on the EQ. I was able to route the USB-C cord around my PC, so now this little Fosi K5 pro sits neatly right next to me, within reaching distance, and the entire experience is fluid. If you have some true HiFi headphones, and you are powering them via your mobo, I get it, you're getting a great experience. For $80 this thing transforms the experience. Video games feel like movies. You can power them to higher volumes, you can tweak Bass/Treble on the fly, and this thing is built solidly. When I plugged it in, I raved to my friend who has Beredynamics 770's.... he caved and bought a Fosi Audio K5 as well. He thanked me for weeks. The audio coming out of this thing into some quality headphones is nothing like I've ever experienced. Everything else -- car audio, audio via my laptop to some crap headphones --- none of it compares. It will change your listening experience 1000%. Would recommend this to anyone.

Excelente. lo conecté al puerto USB C, también trae adaptador para USB A-B, sin problemas. De inmediato se encendió. conecté el rca a mi amplificador. y ualá: Agudos finos, pensé que mis bocinas no daban eso, y sí , el DAC funciona! Se oye el fondo de cada instrumento, los instrumentos en sí usan un amplificador Monoaural, y se mezclan. Este DAC te deja notar ese detalle. Lo he probado con buenas mezclas, se nota la diferencia desde el primer momento. Es calidad de sonido. Para los que apreciamos la sutileza del sonido. apenas me llegó ayer, y es genial. aún falta probar lo en otros aspectos, pero por ahora, se nota en calidad de sonido. los aqudos son puros, transparentes. Se nota el DAc, de inmediato. lo uso con un amplificador fosi BT 10
