On the top of the device, you can find the USB Type-C port, which connects to your smartphone or laptop, and the bottom 3.5mm TRS and TRRS headsets. The device also has volume controls on the left side. an LED indicator on the front, which shows the mode and the sampling rate of the audio signal.

The device is very compact and portable, measuring only 22.4mm x 50mm x 10mm and weighing only 19 grams. You can easily carry it in your pocket or your bag. It comes with a storage box, which gives a very premium look, a USB Type-C cable, Type-c to Type-C data cable, a user manual, a warranty card and certificate, and an MQA subscription voucher.

The build quality of this device is excellent and durable. The metal body feels sturdy and the golden headphone jack gives a premium look. The design of this device is very user-friendly and intuitive. You just need to plug it in and play your music. You don’t need any drivers or software to make it work. You can also use it as a standalone DAC by connecting it to another amplifier or speaker system.

3. HiBy FC6 Modes:

This device is an R2R DAC and an amplifier in one, which means it can convert digital audio signals into analog signals and amplify them to drive your headphones. It also has a special feature called Darwin Architecture, which allows you to switch between two modes: NOS and OS. NOS stands for Non-Oversampling, and OS stands for Oversampling. These modes affect how the device processes the audio signals and how they sound.

4. HiBy FC6 Features:

The most interesting feature of this device is the Darwin Architecture, which lets you choose between two modes: NOS and OS. NOS mode means that the device does not apply any oversampling or filtering to the audio signal, which preserves its original shape and quality. This mode sounds more analog and warm, with rich details and textures.

OS mode means that the device applies to oversample and filtering to the audio signal, which smooths out its edges and reduces noise. This mode sounds more digital and clean, with crisp clarity and accuracy. You can switch between these modes by pressing the mode button on the front of the device. You can also see the mode on the LED indicator: red for not playing, yellow for 32 to 45kHz, blue for NOS, and green for OS. Now let’s move on to the sound quality of this device.

The HiBy FC6 USB Headphone R2R DAC/AMP with Darwin Architecture NOS/OS Model uses an R2R ladder DAC chip, which is a rare and expensive type of DAC that can deliver natural and smooth sound with low distortion and high dynamic range. The device also has a powerful amplifier that can drive headphones with up to 600 ohms of impedance. The device supports high-resolution audio formats, such as PCM768 and DSD512.

5. HiBy FC6 Sound:

To test the sound quality of this device, I used several headphones with different impedances and sensitivities: I found that this device can drive all these headphones very well without any distortion or clipping. It can also handle all music genres and formats without any problem. It goes 31-step hardware volume control with physical buttons for convenient and high-quality volume control.

The sound quality of this device is very impressive and enjoyable. It has a neutral and balanced sound signature that does not favor any frequency over another. It has a tight and deep bass that does not bleed into the mids or overpower them. It has a smooth and natural midrange that does not sound recessed or veiled.

It has a clear and crisp treble that does not sound harsh or sibilant. The soundstage of this device is wide and spacious, with good separation and imaging. It can create a realistic sense of depth and distance between different instruments and vocals. It can also reproduce subtle details and nuances in the music, such as reverb, echo, or breath.

The most noticeable difference between the two modes is the timbre and the texture of the sound. NOS mode sounds more organic and warm, with a softer and rounder tone. It also sounds more dynamic and expressive, with greater contrast between loud and soft sounds. I prefer the FC6 because I like its R2R DAC chip and its Darwin Architecture feature that let me switch between two modes with different sound characteristics. I think it offers more versatility and customization than these devices.

I am impressed with the NOS mode over OS mode because I like its warmer and smoother sound, which suits my musical preferences better. However, I think both modes have their own merits, and they can appeal to different listeners with different tastes. You can experiment with these modes and see which one suits you better. Let me know in the comment section which mode suits you best.

6. HiBy FC6 Review:

The only thing that I don’t like about the design of this device is that it does not have a battery or a charging port. This means that it relies on the power supply of your smartphone or laptop, which can drain their batteries faster. It also means that you cannot use it with devices that do not have a USB Type-C port, such as iPhones or older laptops.

So, what do I think of this device? I think this device is amazing. It offers excellent sound quality, design, features, and versatility for a reasonable price. It is ideal for anyone who wants to enjoy high-resolution audio from their smartphone or laptop with different sound signatures and options.
