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

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

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.

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.

Not notceable improvment
Did not find a commensurate improvement of audio from my PC laptop. Technically, yes it did have a slight improvement. But it is very low on magnitude and quite miss-able for most listeners.

Bon rapport qualité/prix, prises optique, co-axial et RCA en sortie. Alim USB C
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

初めてのヘッドホンアンプにどうぞ!
🎧 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。

No more coil whine noise through my headphone when I game on PC!
The packaging comes with optical, USB-C/A cable, 3.5mm jack splitter for mic and headphone. The DAC is well built just like other Fosi products, solid gunmetal aluminium enclosure. Front: All the aluminium knobs feel high quality. The tone controls have a midpoint tactile stop. The volume control uses a Taper-A pot, which also serves as a power and input switch. Back: The USB-C port was slightly offset and the connector was a bit difficult to insert. Consider enlarging the hole for the USB-C port on the backplate a bit so that the connector doesn't rub against i How does it sound? First, I compared the K5 Pro to the onboard audio on my Asus B550A motherboard (SupremeFX S1220A), which is already pretty decent. However, when I played games, the motherboard produced a ton of coil whine noise that originated from my GPU. The DAC completely eliminated the coil whine noise when I used both the optical and USB modes. As far as sound quality, I couldn't hear any difference between the S1220 and the K5 Pro when I used a QC25 headphone. I also tried switching between the optical and USB modes to see if I could hear any difference, but there was none. Some people don't like the tone controls because they affect the sound quality, but I found them very useful for adjusting the sound to my taste. I often tweak them depending on the content I'm listening to. The playback bitrate of 96kHz works with USB, and 192kHz works with the optical. I didn't test the Coax input because I don't have one. The maximum microphone recording bitrate is 1 channel, 24bit, at 48kHz. Room for improvement: I suggest keeping the naming short and just including the model and brand name, like the TB10D. No need to print the entire 'MINI STEREO GAMING DAC' on the front. It would be useful if the device could remember the last input mode when there is a power loss, as well as the last power mode. For example, if the device lost USB power while it was on, it should turn on again when the USB power is restored. Consider enlarging the hole for the USB-C port on the backplate so that the connector doesn't rub against it.
