- Compact Yet Powerful: The SK02 employs a minimalist and stylish design language. Despite its small size, it boasts mighty features. It supports DSD256 and PCM 32bit/384kHz high-resolution decoding, along with 3.5mm single-ended and 4.4mm balanced headphone outputs. Its robust power can easily drive a wide range of headphones and IEMs with an impedance range of 16-300 ohms.
- Stunning Performance: It features a high-end ESS SABRE ES9038Q2M DAC and SGM8262 op-amps. Its excellent circuit design ensures superior parameters with a SNR as high as 120dB, a low noise floor of only 3.7μV, and an incredibly low THD of 0.001%. The 4.4mm balanced output power reaches an impressive 1100mW at 32 ohms. The exceptional high-resolution capability and pure sound quality make every listening experience an extraordinary sensory journey.
- User-Friendly Design: The SK02 requires no drivers and offers plug-and-play convenience. It integrates a big multi-functional control knob, allowing easy access to power on/off, play/pause, and volume adjustments. The unit features quick-switch buttons for high/low gain and input modes. Additionally, its colorful indicator lights enable effortless identification of the current working mode and the song's sampling rate.
- Remarkable Versatility: Supports USB and optical input, widely applicable for decoding with computers, laptops, CD players, TVs, and projectors. Not only can it function as a headphone amplifier, but it can also serve as a preamp, pairing with active speakers or an amplifier like Fosi Audio V3, ZA3, TB10D amp, and passive speakers to form a desktop listening or home audio system.
- Exquisite and Durable: The SK02 is crafted from a single piece of aluminum alloy using CNC machining and a delicate sandblasting process. This not only gives it an exquisite appearance but also ensures lasting durability. In addition, Fosi Audio pledges to provide a 24-month worry-free warranty and responsive customer service to all users.

I’ve been very pleased with the Fosi Audio SK02 + SK01 Desktop DAC/Headphone Amp overall. The compact form factor makes these units easily portable, and the equalizers perform remarkably well, offering precise audio adjustments.
My only minor criticism is the slight noise that occurs when turning the volume knob—it’s not a major issue, but noticeable enough. I would also recommend adding a bit of texturing or ridging to the volume and EQ knobs themselves, as they can be somewhat slippery to grip. This small tweak would greatly improve the comfort and precision of fine-tuning the settings. Otherwise, these devices deliver excellent performance and are a joy to use.
Tôi không ngờ giá trị của sản phẩm lại cao hơn nhiều so với giá thành, thật không ngờ. Tôi sẽ tiếp tục ủng hộ. 👍👍
Used with Hifiman Sundara and the sound is SO amazing clear big sound stage but lacks sub bass and fixed with equalizer apo and now every thing rocks.
Make sure to use balanced cable with sundara cuz the cans will vibrate your brain !
Quite powerful and superb resolution!
Recently I purchased this amp directly from Fosi Audio at discounted price. I received it in India on 10th day. I checked this produced using my I Mac , Sennheiser HD 660S2 HI Resolution balanced wired headphone. Quality of sound is excellent. Before that I was using Bose QC 35 , noise cancelling amp directly connecting to Mac through Bluetooth. When I compared both systems, results are un comparable. Sound quality drastically improved with wired and balanced input through DAC. I am also listening internet radio through this DAC. Quality of sound further changed . I recommend this product for true music lovers.
