• SOMIC Air One ANC — biggest strength: A complete over-ear headphone with 50 mm dynamic drivers, adaptive ANC, transparency mode, 360° head-tracked spatial audio and up to 50 hours of playback per charge.
• SOMIC Air One ANC — biggest trade-off: It's wireless-only. There's no headphone jack, so you can't run it passively from a wired source, and a full charge takes up to 8 hours.
• Fosi Audio DS3 — biggest strength: Audiophile-grade wired decoding — ES9039Q2M DAC, XMOS dual-core processing, 32-bit/768 kHz PCM, native DSD512, 8 digital filters and a 32-band hardware PEQ, all in a 16 g aluminum dongle.
• Fosi Audio DS3 — biggest trade-off: It makes no sound on its own. It needs wired headphones or IEMs, has no microphone and no battery, and it's strictly a USB-C accessory.
• Who each pick is for: SOMIC Air One ANC for commuters, travelers and gamers who want one wireless headset that does everything; Fosi Audio DS3 for listeners who already own good wired headphones and want to hear them at their best.
The SOMIC Air One ANC is the "one device for everything" option. It's a Bluetooth 5 over-ear headphone in black with 50 mm dynamic drivers covering a 20 Hz – 20 kHz range, so the tuning is aimed at full-bodied, everyday listening rather than studio-flat reference sound. The headline feature is personalized spatial audio: 360° dynamic head tracking that keeps the soundstage anchored around you as you move your head. For movies on a tablet, console gaming or just zoning out on a long flight, that's the kind of effect that makes a headphone feel more expensive than its spec sheet suggests.
Who should buy it: anyone who wants one headset for music, calls, gaming and travel, and who values battery life and wireless convenience over wired purity. Who should skip it: critical listeners who want to feed a dedicated DAC, anyone who needs a wired fallback (there's no jack), and buyers who dislike touch controls. In my opinion, it's the better fit for the person who wants zero accessories and zero cables.
Fosi Audio DS3: Who It's For
The Fosi Audio DS3 is a different species entirely. It's a USB-C DAC and headphone amp dongle — no drivers, no battery, no microphone — built around the ES9039Q2M converter with XMOS dual-core processing running at 1.6 GHz. The numbers tell the story: 32-bit/768 kHz PCM, native DSD512, SNR of at least 122 dB, THD under 0.0003%, and 220 mW at 32Ω over the 4.4 mm balanced output. There's also a 3.5 mm single-ended output. In plain terms, this is a device designed to be transparent — to convert and amplify without adding coloration, and to stay quiet enough that you hear the recording, not the electronics.
The feature set is unusually deep for a dongle. It supports both UAC 1.0 and UAC 2.0 with independent volume memory, which matters if you switch between a phone, a PC and a console. You get 8 selectable digital filters and a 32-band hardware-level PEQ configured through a web-based control panel — real tone shaping in hardware rather than software emulation. There's also a hardware-backed spatial mode: a Fosi algorithm that turns multichannel content into a 360° soundscape with a positional cue for directional clarity, aimed at PC, PS5 and Switch use. Physically it's CNC-milled aerospace aluminum with a tempered-glass window, 16 g total, in Galaxy or Obsidian finishes, backed by a 24-month warranty.
Who should buy it: owners of wired headphones or IEMs who want cleaner, more detailed sound from a phone, laptop, PS5 or Switch, and tinkerers who will actually use the PEQ and filter options. Who should skip it: anyone wanting a standalone wireless headphone, anyone who needs a mic for calls, and casual listeners who won't notice or use the advanced tuning tools. It also only works with USB-C hosts.
• Best for wireless freedom → SOMIC Air One ANC. Bluetooth 5, no cables, no dongle to lose.
• Best for battery life → SOMIC Air One ANC. Up to 50 hours with ANC off versus a battery-free dongle that draws power from your source.
• Best for noise cancelling → SOMIC Air One ANC. Adaptive ANC plus Transparency mode and a quad-mic array; the DS3 has no noise control at all.
• Best for sound quality with your own headphones → Fosi Audio DS3. ES9039Q2M, XMOS processing, ≥122 dB SNR and <0.0003% THD are a different tier of fidelity than any Bluetooth headphone.
• Best for gaming and movies on PC or console → depends. The DS3's 7.1 spatial processing suits PC, PS5 and Switch; the SOMIC's head-tracked 360° audio suits wireless, lean-back viewing.
• Best for calls and meetings → SOMIC Air One ANC. It has microphones; the DS3 deliberately does not.
• Best for tweakers → Fosi Audio DS3. 8 filters, 32-band PEQ, dual UAC modes and firmware upgradability.
• Best for travel and commuting → SOMIC Air One ANC. Over-ear comfort, ANC and one charging cable instead of a wired stack.
If I had to pick one, I'd buy the SOMIC Air One ANC — but only because it's the more complete product for most people. It does music, calls, gaming, travel and noise cancelling in a single wireless package, with battery life that removes charging anxiety. The Fosi Audio DS3 is the better audio device, and if you already own serious wired headphones, I'd recommend it without hesitation: the DAC architecture, balanced output and PEQ make it a genuine upgrade to everything you plug into it. Buy the SOMIC if you want one thing that does it all; buy the DS3 if you want the best possible sound from gear you already have.
They're not directly comparable — the SOMIC is a wireless headphone, the DS3 is a wired DAC/amp. For all-in-one convenience and ANC, the SOMIC wins. For pure fidelity with your own headphones, the DS3 wins.
No. The DS3 has no speakers and no battery — it's a DAC and amplifier that must be connected to wired headphones or IEMs via the 3.5 mm or 4.4 mm balanced output, and to a USB-C source.
No. The data sheet lists no headphone jack, so it's a wireless Bluetooth headphone only. If you need a wired option, the DS3 route is the one to take.
For wireless console and PC gaming with head tracking and no cables, the SOMIC Air One ANC fits better. For positional clarity through wired headphones on PC, PS5 or Switch, the DS3's spatial processing and low-noise output are the stronger choice.
