Yep, I'm pretty interested.

Info on price and release in the EU? Partner?

Another question: it says that it is fully compatible with the console. But I can't find any information that it's UAC 1.0. That would be my main selling point. So how is it?

Congratulations!

Thanks for your interest!

The retail price will be under €200 in EU and you'll be able to purchase it from our partner Audiophonics.

The K7 supports both UAC 1.0 and 2.0. You can simply switch between them by pressing a shortcut key.

Great, thanks for the answer.

“Only” 200€? I hope the sound performance will be "good", at least better than dongles and FiiO K17.

Yes, I have also read elsewhere that expectations must not disappoint 😉

Let me ask you this: is it possible to get a demo unit for impressions here in the forum? I am in Berlin / Germany.

Sent!

I am very happy for this opportunity and I will be happy to post my honest impressions here. I'm sure many others are waiting for it.

It was finally time to produce such a specific device. As a gamer with PC and consoles, I have always had a hard time with dongles and I didn't like it that much the FiiO K17 (only higher-end dac/amp which is UAC 1.0 compatible).

Thank you for your attention. We plan to start shipping the rewards around March 10th.:slight_smile:

Are you serious m8 ? There are plenty of DAC+AMPs that support UAC 1.0 and 2.0.
For eg. all IFI Audio products support it and they even switch automatically without any manual setting like FiiO implements.

Just to give a comparison in the same price range, the latest FiiO K11 R2R and IFI Zen DAC 3 both which I own supports PC and all consoles (I have a PS5). As I said before on the FiiO you have to switch UAC in the settings. On the IFI it switches automatically.

Both the FiiO and IFI models I listed also use better amplifiers, latest XMOS XU316 USB chipset and so on.

My advice: UAC 1.0 support shouldn’t be the reason to buy this Fosi product. If you need a mic input + Bluetooth, then perhaps yes. But know that there are also other DACs/dongles with these features to compare.

Let me summarize the positioning of the K7 briefly:

1. High-Quality Decoding and Amplification Performance

The K7 features the highly regarded AK4493S chip, which has gained a strong following. Based on our research, this chip is the most popular choice among users in its class and price range.


2. Comprehensive and Practical Features

As a desktop DAC/amp, the K7 supports mainstream digital input modes for decoding and analog output, making it versatile and practical for various setups.


3. User-Friendly Design

The K7 is designed with ease of use in mind. From the display screen to the shortcut buttons and dual large knobs, every detail is tailored to enhance the user experience.


4. Game-Inspired Aesthetic

Its design reflects a gaming-inspired style. Our research indicates that a significant number of headphone HiFi enthusiasts are also avid gamers. Many users work from home, listen to music, and play games on the same desktop setup. The K7 is specifically designed to cater to this multi-functional desktop scenario.

Any plans for an Xbox compatible version?

Compatibility with Xbox series consoles has been a “challenge”, but we have been actively evaluating and researching potential solutions. :slight_smile:
