The Best Audiophile Headphones for Gaming
We weighed five headsets on driver size and connection; the ROG Kithara has the largest driver size, and the Sundara costs the least.
By Alex Morgan, PC Hardware Editor
12 min read5 products evaluated

Open-back audiophile headphones give a wider soundstage than most gaming headsets. Every pick is open-back and cost $100 or more, ordered by driver size.
We ranked these headsets on driver size, connection and design using manufacturer specifications; we did not test these headsets ourselves, and where a maker leaves out driver size, we say so.

Our Picks
Largest Drivers1 of 5
ASUS ROG Kithara Planar Magnetic Gaming Headphones
What the ROG Kithara brings to the table is 100mm HIFIMAN planar drivers tuned by ROG, plus a full-band MEMS boom microphone.
Best for
- Players who favour a fuller low end.
Skip if
- Skip it if this is a deal-breaker for you: open-back leaks sound both ways.
Why we like it
The headband has eight adjustment levels with a metal frame and hinges, extra ear pads come in the box, and the mic covers 20Hz to 20kHz. Plugs include 4.4mm balanced, 3.5mm and 6.3mm, plus a USB-C adapter. On driver size it leads this guide at 100mm, ahead of the Fosi i5 (97mm).
It shares a wired connection with the Fosi i5 and Sundara; the MMX 330 Pro goes with a wired 3.5mm connection. It shares an open-back planar magnetic design with the Fosi i5 and Sundara; the DT 990 Pro goes with an open-back design. It is the only pick here with an on-cable MEMS boom mic microphone; the MMX 330 Pro has a condenser microphone instead.
Because it is open-back, other people in the room will hear it, and it will not block outside noise. When we checked, only the DT 990 Pro and cheaper picks cost less, and the MMX 330 Pro cost more.

Premium Pick2 of 5
Fosi Audio i5 Open-Back Planar Magnetic Headphones
What the Fosi i5 brings to the table is a 97mm diaphragm, plus CNC metal and walnut construction.
Best for
- Spending more than the MMX 330 Pro costs for the fullest feature set in this group.
Skip if
- Choose another pick if you can't accept this: open-back leaks sound both ways.
Why we like it
It also offers a 97mm driver size. Its 97mm planar diaphragm is 2 microns thin with a sputtered silver alloy coating. A memory-steel headband, multi-axis pivoting cups and silicone sliders handle the fit.
Its 97mm driver size ranks second of 3 here, behind the ROG Kithara (100mm) and ahead of the MMX 330 Pro (45mm). Like the ROG Kithara and Sundara, it has a wired connection, while the MMX 330 Pro uses a wired 3.5mm connection. Like the ROG Kithara and Sundara, it has an open-back planar magnetic design, while the MMX 330 Pro uses an open-back design.
Because it is open-back, other people in the room will hear it, and it will not block outside noise. It was the most expensive pick when we checked, so weigh what it adds over the MMX 330 Pro.

- Driver size
- 97mm
- Connection
- Wired
- Design
- Open-back planar magnetic
- Microphone
- None
Pros
- 97mm drivers
- No charging or pairing needed
- Open-back for a wider soundstage
- 97mm diaphragm
Cons
- Open-back leaks sound both ways
- No built-in microphone
- Costs more than the Sundara at the time of writing
Condenser Microphone3 of 5
beyerdynamic MMX 330 Pro
The MMX 330 Pro stands out for open-back staging, and it adds a plug-in design with no software needed.
Best for
- Buyers who want a condenser microphone.
Skip if
- Skip it if this is a deal-breaker for you: open-back leaks sound both ways.
Why we like it
It also offers a 45mm driver size. Its 45mm driver size is the smallest in this group; the ROG Kithara leads at 100mm. No other pick in this guide offers a wired 3.5mm connection; compare the Fosi i5, which has a wired connection.
Like the DT 990 Pro, it has an open-back design, while the ROG Kithara uses an open-back planar magnetic design. A condenser microphone is unique to it among these picks, while the ROG Kithara uses an on-cable MEMS boom mic microphone. A 3.5mm plug means it works with a controller or front-panel jack; on PC, a separate mic and headphone jack may need a splitter.
Because it is open-back, other people in the room will hear it, and it will not block outside noise. Its price falls between the ROG Kithara and the Fosi i5, based on our last check.

- Costs more than the Sundara at the time of writing
The catch
If driver size is your priority, the ROG Kithara (100mm) is the stronger choice.
Lowest Price Here4 of 5
HIFIMAN SUNDARA Planar Magnetic Headphones
The Sundara stands out for a diaphragm 80% thinner than the HE400 series, and it adds a full-size over-ear design.
Best for
- Spending as little as possible, with the DT 990 Pro the next step up.
Skip if
- Skip it if this is a deal-breaker for you: open-back leaks sound both ways.
Why we like it
The metal headband and weight-spreading strap suit long listening. Being open-back, it leaks sound and lets room noise in, so it suits a quiet room. Its metal headband and weight-spreading strap keep pressure off the top of the head.
HIFIMAN recommends about 150 hours of burn-in, and the 3.5mm connectors are sturdier than earlier versions. Like the ROG Kithara and Fosi i5, it has a wired connection, while the MMX 330 Pro uses a wired 3.5mm connection. Like the ROG Kithara and Fosi i5, it has an open-back planar magnetic design, while the MMX 330 Pro uses an open-back design.
Because it is open-back, other people in the room will hear it, and it will not block outside noise. It undercut the DT 990 Pro and every other pick on price at the time of writing.
Key specs
- Connection
- Wired
- Design
- Open-back planar magnetic
- Microphone
- None
Pros
- No charging or pairing needed
- Open-back for a wider soundstage
- Diaphragm 80% thinner than the HE400 series
- Full-size over-ear design
Cons
- Open-back leaks sound both ways
- No built-in microphone
- No published driver size
The catch
The maker doesn't give its driver size; if that figure matters, the ROG Kithara comes in at 100mm.

beyerdynamic DT 990 Pro (250 Ohm)
beyerdynamic's DT 990 Pro is a 250-ohm open-back headphone.
Best for
- Buyers who want 250-ohm load suited to audio interfaces.
Skip if
- Choose another pick if you can't accept this: open-back leaks sound both ways.
Why we like it
It works best from an audio interface or amp rather than a controller jack. It shares an open-back design with the MMX 330 Pro; the Fosi i5 goes with an open-back planar magnetic design. It also comes with a 250-ohm load suited to audio interfaces and a studio reference design.
Because it is open-back, other people in the room will hear it, and it will not block outside noise. It was priced above the Sundara and below the ROG Kithara at the time of writing. There is no published driver size figure, whereas the ROG Kithara comes in at 100mm.
Key specs
- Connection
- Wired, 250 ohm
- Design
- Open-back

Pros

How We Chose These Audiophile Headphones for Gaming
Alex Morgan compared the manufacturer specifications, connectivity, warranty terms and compatibility of every pick. Figures come from the makers unless a third-party source is named; we did not test these products ourselves.

- What we compared
- We lined up five headsets on driver size, connection, design and microphone as the makers state them. These are research figures, not bench results: 2 of 5 picks leave out driver size.
- What every pick has in common
- All 5, from the ROG Kithara to the DT 990 Pro, state connection, design and microphone.
- Where the specs have gaps
- The Sundara and the DT 990 Pro give no driver size.
- Price range
- At our last check the picks ran from the Sundara ($100 to $150) to the Fosi i5 ($500 to $1000).
