Fosi Audio used to be rather easy to categorize. Affordable desktop amplifiers, DACs, and other compact components were its bread and butter, usually with enough performance to make considerably more expensive competitors a little uncomfortable.
That description no longer tells the whole story.
Over the past year, Fosi Audio has pushed much harder into the personal audio category with headphones, IEMs, headphone amplifiers, portable components, and streaming products. We have covered a lot of them at eCoustics, and while not every new product is aimed at the same listener, the broader strategy has become increasingly clear: Fosi wants a much larger piece of the Head-Fi market.
CanJam SoCal 2026, which takes place August 29-30 at the Irvine Marriott in Orange County, will give the company another opportunity to make that case. Fosi Audio is bringing four new products for attendees to see and hear: the ZH1 Desktop DAC & Headphone Amp, Carbon12 IEM, DISC Nano Portable CD Player, and S3 Lite Streaming Digital Transport.
All four are interesting for different reasons, particularly as Fosi continues to stretch beyond the inexpensive desktop amplifiers that established the brand. But we are saving the most intriguing one for last. The S3 Lite takes a decidedly different approach to affordable network streaming, and at $199.99, it could become a rather disruptive little black box for listeners who already own a DAC they have no intention of replacing.
ZH1 Desktop DAC & Headphone Amp

To start things off, the ZH1 Desktop DAC & Headphone Amp is designed to bridge music, entertainment, and gaming in a compact desktop component.
According to Fosi Audio’s latest specifications, the ZH1 uses an ESS ES9039Q2M DAC and supports PCM playback up to 768kHz and DSD512. That is notably different from the prototype we saw at CanJam London, which was built around a pair of Cirrus Logic CS43131 DACs, suggesting Fosi has made some significant changes ahead of production. The balanced headphone output is rated at up to 2,000mW, which should give it enough power for a wide range of full-size headphones.
The ZH1 also incorporates Fosi Audio’s AI-assisted EQ system. Rather than requiring users to manually adjust individual parameters, Fosi says the system can create a personalized EQ curve based on the listener’s stated sonic preferences. Customizable RGB ambient lighting is also included for those who want their desktop audio system to look a little more like their gaming rig.
Multiple input and output options are designed to make the ZH1 suitable for both conventional desktop listening and gaming setups. It also expands Fosi Audio’s growing gaming and personal audio lineup alongside the C3 Gaming DAC & Headphone Amp.
Fosi Audio has not provided a complete set of specifications ahead of CanJam SoCal, but the ZH1 is expected to be available in late September for $149.99.
Carbon12 In-Ear Monitor (IEM)

The next new product Fosi Audio is showing at CanJam SoCal 2026 is the Carbon12 In-Ear Monitor (IEM), and it represents another significant step into a category the company was barely involved in a year ago.
Fosi is positioning the Carbon12 as a premium HiFi IEM built around what it describes as the world’s first UTPT ultrathin pure carbon-fiber diaphragm. Unlike more common composite diaphragms that incorporate carbon fiber with other materials, Fosi says its UTPT design uses pure carbon fiber to combine very low mass with high rigidity.
The Carbon12 uses a 12mm dynamic driver housed inside a TC4 titanium alloy body with a forged carbon-fiber faceplate. Internally, Fosi has incorporated a dual-chamber acoustic structure and balanced pressure-relief system designed to control airflow and driver behavior.
Fosi is tuning the Carbon12 for a warmer presentation with an emphasis on vocals, which should make it rather different from some of the brighter and more analytical IEMs currently crowding the $150 segment. We will reserve judgment on that until we actually hear it at CanJam.

DISC Nano Portable CD Player

Physical media has found new life over the past few years, and CDs are increasingly part of that conversation. New CD players are appearing at almost every price point, which makes Fosi Audio’s next CanJam SoCal 2026 debut rather timely.
The DISC Nano Portable CD Player is designed for listeners who want to take their discs with them without carrying something the size of an early 1990s Discman. Fosi describes the DISC Nano as the world’s smallest portable CD player, a claim we would like to see backed up with final dimensions before handing over the trophy.
Its distinctive half exposed disc design puts the CD itself on display, combining some of the tactile appeal of physical media with features that did not exist when portable CD players ruled backpacks and airline tray tables.
The DISC Nano uses a Cirrus Logic CS43198 DAC and incorporates ESP electronic anti-skip protection to improve playback stability when used on the go. Fosi has also equipped it with an internal rechargeable lithium battery, so it does not need to remain tethered to an external power source.
Connectivity is unusually comprehensive for something this small. The DISC Nano provides 3.5mm and balanced 4.4mm headphone outputs, along with an optical digital output for use with an external DAC or audio system. Bluetooth transmission also allows CDs to be played through compatible wireless headphones, earbuds, and speakers.
Fosi has also incorporated an N52 magnetic rear panel, allowing the player to attach to compatible magnetic mounts and accessories. Some early descriptions refer to this as MagSafe compatibility, although we would not interpret that as MagSafe wireless charging unless Fosi confirms that capability.

Price & Availability
The Fosi Audio DISC Nano is expected to arrive in late September 2026 for $99.99 MSRP.
At that price, the DISC Nano might be more than a novelty. A genuinely portable CD player with balanced headphone output, Bluetooth, optical digital output, an internal battery, and a $100 price tag is exactly the sort of product that could make the CD revival a little more interesting.
S3 Lite Streaming Digital Transport

Rounding out the new products Fosi Audio is bringing to CanJam SoCal 2026 is the S3 Lite Streaming Digital Transport, and this might be the most interesting of the four.
The S3 Lite takes its inspiration from the previously released S3 Streamer/DAC/Preamp, but removes the onboard AKM DAC, analog output stage, and physical audio inputs. The idea is straightforward: if you already own a DAC that you like, why pay for another one?
That makes the S3 Lite less of an all in one streamer and more of a dedicated digital bridge between streaming services and an existing HiFi system. It supports dual band Wi-Fi 6 and Bluetooth 5.3, along with Google Cast, AirPlay 2, DLNA, Spotify Connect, TIDAL Connect, Qobuz Connect, and Bluetooth. Fosi also lists Roon Ready support, although the company said in July that certification was still being completed, so we would like to see final confirmation on that point.
More importantly, calling it the S3 Lite undersells one aspect of the design. The S3 Lite provides USB-A, optical, and coaxial digital outputs, whereas the full S3 does not offer USB or coaxial digital output. For anyone planning to use an external DAC, that actually makes the less expensive model more flexible.
The USB output supports PCM up to 32-bit/768kHz, although DSD is not currently supported. Fosi also includes a 10 band graphic EQ, a Bluetooth remote with a claimed 15 meter operating range, and a 12V trigger output that can power compatible downstream components on and off with the streamer. The chassis measures just 147mm wide, making it easy to integrate into a desktop or compact two channel system.
Ultimately, the S3 Lite is not trying to replace your DAC, preamplifier, or entire system. It is designed for listeners who already spent money on those things and simply want to add modern streaming, including USB digital output, without dismantling everything else.
The Competition
FiiO’s SR11, currently selling for around $119.99, is probably its most direct rival because it is also a dedicated digital streamer with USB, optical, and coaxial outputs and support for PCM up to 32-bit/768kHz. The catch is that its streaming ecosystem is considerably narrower, concentrating primarily on Roon Ready and AirPlay.
The WiiM Pro at $169 and WiiM Pro Plus at $249 offer considerably broader software and streaming service support, along with excellent app integration, but their optical and coaxial digital outputs top out at 24-bit/192kHz and neither offers USB audio output. If you are only feeding an external DAC, the Pro Plus’ upgraded internal DAC becomes largely irrelevant.
Moving up to $349, the WiiM Ultra adds USB digital output, HDMI ARC, analog and phono inputs, a 3.5 inch touchscreen, an internal ESS DAC, subwoofer output, and much more extensive EQ capability. Its digital outputs, including USB, are limited to 24-bit/192kHz, but it is clearly the more comprehensive system hub if you actually need all of those additional features.
The Bluesound NODE NANO, at roughly $429, is another strong alternative with BluOS, an ESS ES9039Q2M DAC, USB, coaxial, and optical digital outputs, Roon Ready certification, AirPlay 2, Spotify Connect, TIDAL Connect, and access to a much broader streaming ecosystem. It tops out at 24-bit/192kHz, but BluOS remains one of the more mature streaming platforms available at this end of the market.

The Bottom Line
Fosi Audio’s presence at CanJam throughout 2026 makes one thing increasingly clear: the company is no longer content being known primarily for affordable desktop amplifiers. Personal audio has become a significant part of its strategy, and the four products heading to CanJam SoCal cover a surprisingly broad range of categories.
The ZH1 looks like a lot of desktop DAC/headphone amplifier for $149.99, while the Carbon12 represents Fosi’s most ambitious move yet into IEMs. The DISC Nano is certainly the most visually distinctive of the group and arrives at an intriguing $99.99, although portable CD players with balanced headphone outputs and Bluetooth already exist.
The S3 Lite is the one we find most interesting. Dedicated digital transports are nothing new, but Fosi’s combination of USB, optical, and coaxial outputs, support for PCM up to 768kHz over USB, eight streaming protocols, Wi-Fi 6, and a $199.99 price makes it an unusually focused option for listeners who already own a DAC they have no desire to replace. Instead of adding more hardware simply to make the specification sheet longer, Fosi removed the parts that audience does not need. That makes a lot of sense.
Of course, specifications and aggressive pricing only tell us so much. The eCoustics team will be at CanJam SoCal 2026 on August 29 and 30, where we will get a closer look at all four products and share our listening impressions after the show.
