How We Research
We compare products from their published specs and features; the verdicts below are our independent editorial opinions.
If you want a plug-and-play desktop DAC and headphone amp that upgrades the sound from your PC, TV or console without any software, choose AIYIMA DAC-A2; if you need a wireless gaming headset with 7.1 surround sound, a detachable mic and RGB lighting for your console or phone, choose ATTACK SHARK G800.
• AIYIMA DAC-A2 — biggest strength: it's a true desktop audio hub. USB, optical and coaxial inputs, RCA and 3.5mm outputs, front-panel bass and treble knobs, and 160mW RMS at 32 Ohms of driving power. No drivers, no setup.
• AIYIMA DAC-A2 — biggest trade-off: it's a stationary component. It needs 5V DC power, it has no microphone and no wireless of any kind, and it's built for a desk, not a couch or a commute.
• ATTACK SHARK G800 — biggest strength: it's a complete wireless gaming headset. Bluetooth plus 2.4G plus wired, virtual 7.1 surround, a detachable microphone, RGB lighting and a 1000mAh battery.
• ATTACK SHARK G800 — biggest trade-off: it's a headset, not a converter. It only handles audio through its own drivers, with a 20Hz–20,000Hz range, so it can't feed your speakers or upgrade an existing stereo.
• Who each is for: AIYIMA DAC-A2 for someone who wants cleaner, tunable sound from a PC or home system. ATTACK SHARK G800 for someone who wants one wireless headset that covers gaming across PC, PlayStation, Xbox and mobile.
The AIYIMA DAC-A2 is a compact digital-to-analog converter and headphone amplifier that sits on your desk and replaces whatever mediocre audio chip is inside your computer. It takes digital audio in three ways — USB, optical and coaxial — and turns it into analog out through RCA jacks or a 3.5mm jack. That last part matters: RCA outputs mean it can feed active speakers or a home stereo, not just a pair of headphones. Plug it into a PC, a MAC, a Linux machine, a television or a gaming console and it works immediately, with no drivers or software downloads. The DC 5V power input keeps it running as a standalone unit rather than drawing power from your USB bus.
The feature I keep coming back to is the front-panel tone control. Bass and treble knobs are physical rotaries you can reach without touching a menu, which is unusual at this price tier of desktop gear. If your headphones run thin or your speakers get boomy in a small room, you can nudge the sound without installing an equalizer. The volume knob is tactile too, so adjusting on the fly feels natural.
On power, AIYIMA rates the DAC-A2 at 160mW RMS at 32 Ohms and says it drives headphones from 16 to 200 Ohms. That covers most everyday cans — typical gaming headsets, portable models and plenty of studio-style headphones. High-resolution playback goes up to 24-bit/192kHz over optical or coaxial, which is more resolution than most people's source files will ever use.
Who should buy it? Someone with a desktop PC and a decent pair of headphones or active speakers who wants a clean, low-noise floor, a wide soundstage and hands-on tone control. Competitive gamers chasing pinpoint audio cues benefit from the low noise floor and the ability to push treble for footsteps. Home theater users benefit from the optical input and RCA outputs.
Who should skip it? Anyone who needs a microphone, wireless freedom or surround processing. The DAC-A2 has two channels, analog output only, and no mic path at all. It also won't help you on a couch — it's cable-mounted and stationary by design.
ATTACK SHARK G800: Who It's For
The ATTACK SHARK G800 is a wireless gaming headset built around three things: surround sound, comfort and durability. It uses hardware-driven virtual 7.1 surround, which means the processing happens in the headset rather than relying entirely on your PC's software. The claimed benefit is acoustic positioning precision — the kind of directional audio that helps you tell whether footsteps are behind you or to your left. For FPS players, that's the whole pitch. The sheet names God of War, Fortnite, PUBG and CS as the kind of titles it's aimed at.
Comfort is clearly a design priority. You get over-ear cups with skin-friendly protein leather and breathable memory foam, plus a fully padded headband. Memory foam matters for long sessions because it spreads pressure instead of creating hot spots, and breathable foam helps with heat buildup — the usual complaint about closed-back gaming headsets. The frame is ultra-light aluminum alloy, described as sturdy, corrosion-resistant and fade-resistant, resilient against bumps and travel while keeping weight down.
Connectivity is the G800's real advantage over a desktop DAC. It supports Bluetooth, 2.4G wireless and wired listening, with a 3.5mm jack, and it's listed as compatible with PS4, PS5, new Xbox, Xbox Series X/S, Switch, tablet, PC, laptop, iOS, iPad and mobile phones. That's an unusually broad list for one headset. There's one caveat the sheet flags honestly: if you're connecting to an older Xbox One controller, you'll need an extra adapter that isn't included. The battery is 1000mAh, and the description leads with plug-and-play. The microphone is detachable, which is a nice touch — you can strip it down for music listening and clip it back on for voice chat. Controls are touch-based, and there's RGB lighting with colorful effects for the aesthetic side of a gaming setup. The frequency range is 20Hz to 20,000Hz, which is the standard full-range span for a dynamic driver headset. It comes in white, includes a user manual, and carries a 1-year manufacturer warranty.
Who should buy it? Console and cross-platform gamers who want one headset for everything — PlayStation, Xbox, Switch, PC and phone. Anyone who values wireless freedom, a detachable mic and RGB flair. Players who game for hours and care about ear comfort.
Side-by-Side: Which Should You Choose?
• Best for speaker or stereo integration → AIYIMA DAC-A2. RCA and 3.5mm outputs let it feed active speakers and home audio gear. The G800 can't output to anything.
• Best for wireless freedom → ATTACK SHARK G800. Bluetooth and 2.4G wireless plus wired as a backup. The DAC-A2 is a stationary, cable-mounted component.
• Best for voice chat and team gaming → ATTACK SHARK G800. It has a detachable microphone. The DAC-A2 has no mic input at all.
• Best for tone control and personal tuning → AIYIMA DAC-A2. Front-panel bass and treble knobs, plus tactile volume control.
• Best for console and mobile gaming → ATTACK SHARK G800. PS4, PS5, Xbox Series X/S, Switch, tablet, PC, laptop, iOS and iPad support in one headset.
• Best for long-session comfort → ATTACK SHARK G800. Protein leather, breathable memory foam and a padded headband are designed for marathon play.
• Best for high-resolution desktop listening → AIYIMA DAC-A2. Up to 24-bit/192kHz over optical or coaxial, with 160mW RMS at 32 Ohms.
• Best for driving demanding headphones → AIYIMA DAC-A2. It's rated for headphones from 16 to 200 Ohms, which the G800 obviously doesn't need to be.
In my opinion, these two products don't really compete — they solve different problems, and the right answer depends entirely on what's missing in your setup. If your computer's audio sounds flat and you want a clean, tunable desktop hub that can feed headphones and speakers, I'd buy the AIYIMA DAC-A2. Its three inputs, two outputs, tone knobs and headphone-driving power make it the more flexible piece of gear for a desk. If instead you want one wireless headset that covers PlayStation, Xbox, Switch, PC and your phone with surround sound and a detachable mic, I'd buy the ATTACK SHARK G800. My pick for the widest range of buyers is the G800, simply because most people shopping in this space want a headset, not a converter.
It depends on the setup. The DAC-A2 improves whatever headphones you already own with a low noise floor and treble tuning for audio cues, but it has no mic and no surround processing. The G800 delivers virtual 7.1 surround and a detachable mic out of the box. For competitive voice-chat gaming, the G800 is the more complete package.
Yes. It's listed as compatible with PC, PS4, PS5, new Xbox, Xbox Series X/S, Switch, tablet, laptop, iOS and iPad, using Bluetooth, 2.4G wireless or a 3.5mm wired connection. Note that older Xbox One controllers need an extra adapter, which isn't included.
AIYIMA rates it for headphones from 16 to 200 Ohms at 160mW RMS at 32 Ohms. That covers most everyday headphones and gaming headsets comfortably. If your headphones are well above 200 Ohms, I'd look at dedicated desktop amps instead.
For pure sound quality on a desktop, the AIYIMA DAC-A2 is the better fit — it bypasses your PC's internal audio, supports up to 24-bit/192kHz over optical or coaxial, and gives you bass and treble control. The G800 is the better choice if you also want wireless freedom and a microphone. Check the current price on Amazon before deciding, since both sit in different budget brackets depending on the day.
