My masterpiece ❤

I have tons of equipment (audiophil) because I want the maximum all time. Switching headphones, using different Dac`s and amplifiers to find the optimum...after using this garbage G6 from soundblaster I was hoping for a long time that a company is taking it more serious than many others. Fosi Audio made it. Not only that I love to use the K7 in gaming, the flexibility and the usage itself...I didn't expect that I will use the bt mode so often. Switching from gaming easily to bt mode and listen music is so nice...the sound is of course not like a e.g. FIIO M15 but for that price is this a masterpiece for me . I love my K7 (KS supporter) and if it's failing I will buy a new one or maybe another new version from Fosi...For years I was hoping that a company is implementing an balanced output...Fosi did it and I'm sooo happy about...setup gaming (squad): beyerdynamic MX300; (solo) beyerdynamic T1 or Fosi i5 ❤. I'm in heaven...All the best and thanks a lot for this great product. Best Regards, Mike

5 stars

Good product for sound i recommended

Fosi K7

Works great and seems well-built. It made my sound quality better than my old pc sound card. for gaming works a treat and finished my desktop setup well for now at least.

Great headphone Amp/DAC

This is a very good headphone amp/DAC for the price. It is easy to set up and it has plenty of ways to connect your source to it, including via the supplied usb cable (it can convert between standard usb and usb-c which is good depending on your pc). The interface is clear and easy to navigate and use for most things. Overall I am very happy with it.

Excellent produit... mais support/software laborieux !

Très bon ampli-casque/DAC :

Esthétique plutôt réussi, très bien fabriqué, ergonomique dans le maniement et la compréhension des fonctions, complet et vraiment très performant en regard de sont prix !

Une étoile en moins cependant...
parce qu'il manque au driver une fonction qui prévient lorsqu'une nouvelle version, obligeant à visiter régulièrement le site pour vérifier si une mise à jours est disponible.
Par ailleurs le package disponible dans la section "Manuels & Downloads" du site pour le K7, ne contient que le driver, mais PAS la dernière version du Firmware et l'update tool qui permet la mise à jour du K7.
Donc là c'est encore plus laborieux car il faut contacter le support pour leur demander si une nouvelle version de firmware est disponible, et de bien vouloir l'envoyer (lien Google Drive)...
Alors que le package de mise à jour du firmware devrait soit être inclus dans celui du driver, ou au moins être mis à disposition avec lui, dans la section "Manuals & Download".
