If you want over-ear headphones with a massive soundstage, deep bass, and gaming-ready isolation for big heads, choose Linsoul SIMGOT EP5; if you need ultra-detailed planar magnetic in-ears with a balanced signature and mobile-ready connectivity for big heads, choose Letshuoer S12.
The choice between these two isn't about which one is "better" in a vacuum, but rather which design philosophy aligns with your head size and listening habits. Both are wired options that demand specific setups, yet they occupy opposite ends of the physical spectrum. One wraps around your ears to create an immersive room-like experience, while the other sits inside them to deliver surgical precision. For anyone struggling with ear cup size or seeking a true wireless alternative that actually fits a larger cranium, understanding these mechanical differences is the only way to avoid buyer's remorse.
• Linsoul SIMGOT EP5: Its biggest strength is the 50mm dynamic driver delivering a vast, open soundstage with powerful bass in a closed-back design; its trade-off is the bulky over-ear form factor that can feel heavy on large frames during long sessions.
• Letshuoer S12: Its biggest strength is the 14.8mm planar magnetic driver offering exceptional high-frequency detail and a neutral, layered sound profile; its trade-off is the in-ear fit which requires precise sealing and may not suit those who dislike pressure in the ear canal.
• Who each pick is for: The EP5 is for listeners prioritizing immersion and bass impact, while the S12 is for critical listeners chasing micro-detail and portability.
The Linsoul SIMGOT EP5 is built for the listener who wants their music to fill a room, even if they are sitting in a small apartment or a busy office. At the heart of this design is a massive 50mm ultra-magnetic wideband dynamic driver. This isn't just a marketing term; it physically displaces more air than smaller drivers, creating the kind of deep, punchy bass and expansive harmonics that smaller in-ears simply cannot replicate. When you pair that driver with a closed-back acoustic chamber, you get a unique balance where the sound feels open and airy, yet isolated from the outside world. This makes it an ideal tool for gamers who need to hear directional cues clearly without disturbing others, or for audiophiles who want a natural vocal presentation without the fatigue often associated with open-back designs.
For someone with a bigger head, the EP5 offers a distinct advantage in comfort and seal. The headband is constructed from stainless steel and ABS materials, featuring a stepless adjustable mechanism. This means there are no clicks or ratchets to struggle with; you can slide the band to find the perfect tension that accommodates a wider skull width without pinching. The ear cups are designed for over-ear placement, wrapping around the ears rather than pressing into them. This is crucial for people who find in-ear monitors uncomfortable or who have larger ear canals that standard tips don't accommodate well. The enclosure material is Acrylonitrile Butadiene Styrene (ABS) with leather padding, providing a soft touch that helps distribute weight across the head rather than concentrating it on a single point.

However, this product is not for everyone. Because it relies on a closed-back design with a 32-ohm impedance and 113dB sensitivity, it is easy to drive directly from a PC or portable player, but the physical bulk is significant. If you are looking for something to slip into a pocket for a quick commute, the EP5 will feel like carrying a small brick. Furthermore, while the soundstage is impressive for a closed headphone, it still has boundaries. You are getting a "room" sound, but it is a contained room. If you prioritize absolute neutrality and transparency above all else, the EP5's tuning, which leans toward a slightly enhanced bass response and rich instrumental textures, might feel too colored compared to a strictly flat monitor. It is best suited for those who value the emotional impact of music and the convenience of a plug-and-play wired connection over the microscopic resolution of a planar driver.
The Letshuoer S12 Ultra is engineered for the listener who demands the highest level of detail retrieval and clarity, particularly in the upper frequencies. Instead of a dynamic driver, this unit utilizes a 14.8mm planar magnetic driver. Planar technology is known for its speed and accuracy; the diaphragm is driven evenly across its entire surface, which eliminates the distortion often found in dynamic drivers at high volumes. The result is a sound signature that is richly layered and perfectly balanced. Highs unfold with natural clarity and airy detail, allowing you to hear the subtle breath of a vocalist or the shimmer of cymbals without any harshness. This makes the S12 a superior choice for critical listening, music production monitoring, or for anyone who wants to dissect a track and hear every instrument in its own space.
For individuals with big heads or those who struggle with the fit of traditional headphones, the in-ear nature of the S12 offers a different kind of freedom. There is no headband to press down on the top of your skull, no clamping force to cause headaches after an hour of use, and no ear cups to interfere with glasses or hair. The housing is made of plastic with a refined Mocha finish, designed to be lightweight and ergonomic. The key to making this work, however, is achieving a proper seal. The package includes various ear tips to help you find the right fit, and once sealed, the passive noise isolation is effective enough to block out ambient chatter. The S12 also addresses the pain point of mobile compatibility by including a DT01 Pro cable with a Type-C connector, meaning you can plug directly into modern smartphones without needing a separate dongle.
The trade-off here is the loss of the "spacious" feeling that comes from over-ear designs. While the planar driver provides excellent imaging, the soundstage is naturally confined within your head. You won't get the feeling of sitting in a concert hall; you will get the feeling of having the instruments placed precisely inside your skull. Additionally, planar drivers generally require more power to reach their full potential compared to the highly sensitive 113dB EP5, though the S12's low impedance makes it manageable on most devices. If you are prone to ear fatigue or find in-ear monitors irritating due to the pressure in the canal, this product will likely frustrate you. It is strictly for those who prioritize sonic fidelity and portability over the immersive, physical sensation of large ear cups.
• Best for battery life → Neither product uses batteries as they are both wired, but the EP5 is easier to drive directly from a phone without a dedicated amplifier, saving your device's power.
• Best for big head comfort (over-ear) → Linsoul SIMGOT EP5, thanks to its stepless stainless steel headband and large ear cups that don't rely on internal pressure.
• Best for big head comfort (in-ear) → Letshuoer S12, as it eliminates the clamping force of a headband entirely, relying instead on a custom seal.
• Best for deep bass and immersion → Linsoul SIMGOT EP5, leveraging its 50mm driver and closed-back chamber for powerful, room-filling low-end.
• Best for detail and clarity → Letshuoer S12, utilizing its 14.8mm planar magnetic driver for superior transient response and high-frequency extension.
• Best for mobile gaming → Letshuoer S12, because the included Type-C DAC cable removes the need for adapters and the in-ear design keeps your ears cool during intense sessions.
• Best for studio monitoring → Letshuoer S12, given its H-2018 target curve alignment and neutral, transparent response suitable for professional work.
• Best for shared spaces → Linsoul SIMGOT EP5, as the closed-back design minimizes sound leakage better than many open designs, keeping your music private.
If I had to choose one based purely on the goal of finding the best true wireless earbuds for big head (or rather, the best wired solution for that demographic), I would lean heavily toward the Linsoul SIMGOT EP5. The sheer comfort of a properly adjusted over-ear headset for a larger cranium is unmatched by anything that goes inside the ear canal. The ability to adjust the headband steplessly ensures that the pressure is distributed correctly, preventing the headaches that often plague users with larger heads when wearing tight gear. The 50mm driver provides a satisfying, physical sensation of bass that feels more "real" and less clinical than the S12. However, if my priority was pure audio fidelity and I needed to carry my setup everywhere, I would switch to the Letshuoer S12 for its incredible detail retrieval and lack of clamping pressure. Ultimately, for someone prioritizing the physical fit and immersive experience of low latency sports earbuds for big head (even though these are wired, the fit principle applies), the EP5 wins on ergonomics and the sheer scale of its audio presentation.
Neither of these products supports Bluetooth; they are both wired connections requiring a 3.5mm or 4.4mm jack. They are excellent alternatives if you prefer zero latency and higher audio quality over wireless convenience.
The Linsoul SIMGOT EP5 offers superior passive isolation due to its closed-back over-ear design, effectively blocking out ambient noise better than the in-ear Letshuoer S12, which relies solely on the seal of the ear tip.
No, both are designed for easy drivability. The EP5 has a high sensitivity of 113dB, and the S12 is compatible with most modern sources, meaning you can plug them directly into a phone or PC without needing a separate amplifier.
Yes, both feature detachable cables. The EP5 uses a dual TRS design with oxygen-free copper, while the S12 uses a 2-pin connector with a silver-plated cable, allowing you to upgrade or replace them easily.
