Excellent
Good, especially if this is a first product in this category. The only thing that I wish was included is the mute button for the mic.

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。

Finally, trouble free Hi-Fi!
Started looking into aftermarket solutions after having problems with my on-board audio. This is a fantastic unit for my powered Audioline speakers and Jamo subwoofer, and for driving my Shure headphones + ModMic, I love it! Works straight out the box. Build quality is exceptional. Sound quality is fantastic. Couldn't be happier. Although.... Why is there no way to switch between outputs! Seems like a massive oversight. Why would anyone only want to drive their headphones and speakers simultaneously? But all in all. I love this thing for the price, will be looking at this brand for future purchases.

Gedigen och mångsidig hörlursförstärkare
Fosi Audio K5 Pro känns mycket välbyggd med ett chassi i metall och lagom tyngd, så den står stadigt på skrivbordet. Reglagen har en skön och gedigen känsla, och det är smidigt att snabbt kunna justera både bas och diskant. Den drivs via USB-C och fungerar samtidigt som ett externt ljudkort, med anslutning för både hörlurar och mikrofon. Jag har testat den med PC, Mac och iPhone 16 Pro Max, och den har fungerat bra med samtliga. Den driver även mina Sennheiser HD58X utan problem. Utöver USB-C finns stöd för optisk anslutning via Toslink samt RCA, vilket gör den flexibel även tillsammans med annan ljudutrustning. En prisvärd, välbyggd och mångsidig liten hörlursförstärkare.

Outstanding Quality
Purchased this audio DAC because i was excited to see that FOSI AUDIO had just come out with a DAC that included headphone microphone input. I was an early adopter of this product and actually paid a premium price through amazon USA, shipped to Canada. I knew the similar FOSI Q4 had an excellent reputation for sound quality but unfortunately did not suit me because of the lack of microphone input. In come the FOSI AUDIO K5 MINI PRO.. I had to give this DAC a try. As soon as you handle this product you know you are getting a quality piece of equipment. Setup is easy, all you do is plug it into your computers USB port. No driver install, just tell your computer to play the audio from the device in your sound setup. Even comes with a dongle to allow for a combined audio/mic headphone set to plug into the separate jacks on the device. Audio quality - 10/10 excellent and an absolute steal for the asking price that I am now seeing on amazon as of DEC 29/2022 Microphone quality - 10/10 If you online game your friends are going to think you have a very fancy microphone with this DACs ability to amplify the microphone input. It can be almost too clear and loud on some headsets but this can be adjusted in the windows input microphone level settings and turned down. I did need to get support from FOSI and they immediately and quickly helped me with my advanced technical question and had my device working well with all my equipment. (I use quite a few different headphones w/mics and had an issue with one of them which FOSI solved) This K5 MINI PRO is on par with some of the very expensive DACS out there. There is only two features I wish that FOSI would add. Some sort of "go to sleep mode" and "auto wakeup on sensing sound" to have this unit automatically turn off after say 30min of inactivity and wake itself when needed. The other would be a volume adjuster for the microphone input. These are just wishes to make an already excellent product even better. You will not be disappointed with this product.
