Audeze LCD-2 vs Fostex T50RPmk4 at a Glance
• Audeze LCD-2’s biggest strength: a 100 mm planar magnetic driver and a warmer sound profile with strong bass response. Trade-off: it uses a 6.35 mm jack, and the product is described as open-back.
• Fostex T50RPmk4’s biggest strength: its planar driver and symmetrical housing design are aimed at responsive sound, localization, and separation. Trade-off: its feature set is more gaming-focused, and it provides no noise control.
• The Audeze has leather-free memory foam earpads and a steel suspension headband; the Fostex has thicker, low-resilience, around-ear pads intended for long gaming sessions.
• Both are wired, over-ear planar magnetic headphones. Neither is a Bluetooth earbud, an in-ear model, or an IPX7-rated waterproof earphone.
• Choose Audeze for warmer, bass-forward listening; choose Fostex for gaming-oriented positioning and a 3.5 mm connection.
The Audeze LCD-2 Classic is an over-ear, open-back headphone with a 100 mm planar magnetic driver. Its stated frequency range is 10 Hz to 50 kHz, and Audeze describes its character as warmer than the regular LCD-2, with notable bass response. That makes it the more natural fit if you want music listening to feel full and substantial rather than prioritizing gaming cues above all else.
The physical details matter for everyday use. It comes with a steel suspension headband and leather-free memory foam earpads. Those materials may appeal to someone who prefers to avoid leather in the ear cushions, while the over-ear format gives the pads room to surround the ears. The 6.35 mm jack is the connection to plan around: check that your intended source has a compatible output or that you have an appropriate connection solution.
Its open-back construction is also a meaningful trade-off. I would favor it for a listening space where sound can be more open to the surrounding room, rather than assuming it will isolate you from noise. Audeze lists sound isolation as a control feature, but does not specify active noise cancellation. There is no basis here to treat the LCD-2 as a noise-canceling headphone.

The Fostex T50RPmk4 is also an over-ear planar magnetic headphone, but its stated strengths point more directly toward gaming. Fostex emphasizes response speed, localization, and separation: the qualities that can help a listener distinguish sounds and judge where they seem to come from. Its symmetrical left and right housing design is intended to reduce differences between the two sides, including differences associated with connectors and internal parts.
That focus may suit a gamer who wants a wired headphone designed around positional audio rather than a warmer, bass-led music presentation. The T50RPmk4 uses a 3.5 mm jack, a more familiar connection format for many audio devices than the Audeze’s 6.35 mm jack.
Comfort is addressed through thicker, low-resilience, around-ear pads. Fostex says they are designed to support a comfortable fit during extended gaming without compromising immersion. That is a useful design intention, especially for long sessions, though the information provided does not establish how the fit will feel on every head or around every pair of glasses. It is wired, and its noise control is listed as none, so it is not aimed at shoppers seeking wireless use or noise management.
Who should skip it: Skip the Fostex if your main goal is the Audeze’s specifically described warm tonality and bass response, or if you need Bluetooth or stated noise-control features.
• Best for warmer, bass-focused listening → Audeze LCD-2. Its product information specifically describes a warmer sound and strong bass response from its 100 mm planar magnetic drivers.
• Best for gaming-oriented localization and separation → Fostex T50RPmk4. Those are central to Fostex’s stated design priorities, making it the clearer match for players focused on distinguishing sounds.
• Best for a 6.35 mm connection → Audeze LCD-2. Confirm your source can accept that plug before choosing it.
• Best for a 3.5 mm connection → Fostex T50RPmk4. Its listed jack may be the more convenient match for equipment with a standard 3.5 mm output.
• Best for leather-free earpad materials → Audeze LCD-2. Its pads are specified as leather-free memory foam.
• Best for thicker, low-resilience around-ear pads → Fostex T50RPmk4. Fostex presents these as a comfort feature for extended gaming.
• Best for someone comparing stated frequency figures → Audeze LCD-2. It has a numerical range of 10 Hz to 50 kHz; Fostex’s information gives only “Wide range.”
• Best for a portable, wireless routine → neither. Both are described as wired over-ear headphones, not Bluetooth earbuds.
The search phrases “best in ear earbuds for glasses wearers,” “best IPX7 waterproof earphones for glasses wearers,” and “best Bluetooth earbuds for glasses wearers” describe a different type of product than either of these. Neither model is an in-ear earbud, neither is identified as waterproof, and both use wired connections. If those features are essential, this comparison is not a match for that shopping need.
Buying Considerations
First, check the connection on the device you plan to use. The LCD-2 has a 6.35 mm jack, while the T50RPmk4 has a 3.5 mm jack. Since both are wired, the physical connection is not a minor detail: it can determine whether a headphone fits your existing setup conveniently.
Next, decide whether your main use is music listening or gaming. Audeze gives a clearer case for a warm, bass-forward listening preference, and it supplies a numerical frequency range. Fostex gives a clearer case for gaming, with its emphasis on response, localization, separation, and symmetrical housings. The specifications do not establish that one headphone is universally better for every recording or game.
Think about your room, too. The LCD-2 is explicitly described as open-back, so it is a more considered choice for a space where you do not need the headphone to keep sound contained or shut out the room. Fostex lists no noise control. Neither product’s supplied details support treating it as an active noise-canceling option.
Finally, if you wear glasses, focus on the earpad design rather than assuming one will automatically fit better. The Audeze specifies leather-free memory foam, while Fostex calls out thicker, low-resilience, around-ear pads. The data describes their materials and design intentions, not the exact comfort experience for an individual wearer. If glasses comfort is your deciding factor, compare the pad details with your frame shape and how long you expect to wear the headphones.
My Verdict
I would choose the Audeze LCD-2 for its explicitly warmer sound, substantial bass response, and leather-free memory foam earpads.
For glasses wearers who want a wired over-ear headphone for music, those details make it my pick, provided the 6.35 mm connection suits the setup.
My recommendation is the LCD-2 for listening first; the Fostex is the more purpose-directed choice for gaming.
Both are over-ear headphones, but their pad descriptions differ: Audeze specifies leather-free memory foam, while Fostex highlights thicker, low-resilience, around-ear pads. The available details do not establish which will be more comfortable with every glasses frame.
The Fostex is the more directly gaming-focused choice. Its stated strengths include response speed, localization, and separation, and its symmetrical housing design is intended to make the left and right sides more closely matched.
No. Both are described as wired, over-ear headphones. Neither product’s details identify Bluetooth connectivity or an IPX7 waterproof rating.
Check the headphone jack on your intended device: the LCD-2 uses a 6.35 mm jack, and the T50RPmk4 uses a 3.5 mm jack. Also weigh the LCD-2’s open-back design and warmer sound against the Fostex’s gaming-oriented focus and lack of listed noise control.
