If you want a true wireless gaming headset with a low-latency 2.4GHz connection, a boom mic, and enough battery for marathon sessions, choose EKSA 2.4GHz; if you need a blackout sleep mask with built-in Bluetooth audio for side sleeping, travel, and all-night listening, choose LC-dolida Sleep Mask. These two products share a wireless chip generation and almost nothing else. One is built for your desk, the other for your pillow. Here's how to tell which one belongs in your cart.
• EKSA 2.4GHz — biggest strength: A dedicated 2.4GHz USB/Type-C link rated under 30ms latency, plus Bluetooth 5.4, a noise-cancelling boom mic, and up to 35 hours of battery.
• EKSA 2.4GHz — biggest trade-off: It's a full over-ear headset with a boom mic and RGB lighting, so it's bulky and clearly designed for gaming setups, not for lying on your side in bed.
• LC-dolida Sleep Mask — biggest strength: Total blackout coverage with a contoured nose shape and a razor-thin 32mm stereo driver built into an ice silk mask, so you can listen lying down, including on your side.
• LC-dolida Sleep Mask — biggest trade-off: Up to 15 hours of battery and no boom mic — it's for sleep, calls in bed, and quiet listening, not competitive play.
• Who EKSA is for: PC, PS5/PS4, Switch and Mac players who want low-latency audio and clear team chat.
• Who LC-dolida is for: Side sleepers, travelers, and anyone who wants music or calls while blocking out light.
The EKSA 2.4GHz is a gaming headset first and everything else second. Its headline feature is the under-30ms 2.4GHz wireless link, which is the whole point: when you're playing something fast, you want footsteps and gunfire to land in the same instant as the on-screen action. The headset also carries Bluetooth 5.4, so you can pair it with a phone or laptop without dongles, and it ships with a Type-C to USB adapter and a Type-C to 3.5mm cable for wired use when you want it.
Audio comes from tuned 40mm dynamic drivers with a 20Hz–20,000Hz range and 80 ohm impedance. EKSA splits tuning into a game mode for positional accuracy and a music mode for a fuller, warmer sound — one tap switches between them. In my opinion that dual-mode approach is the smartest thing here, because a headset tuned purely for competitive shooters usually sounds thin for music, and this one gives you both without a second pair of headphones.
The practical details matter too. At 169g it's genuinely light for an over-ear headset, with breathable mesh earpads and an adjustable, foldable headband. The noise-cancelling boom mic folds into the earcup when you're not using it, which keeps it out of the way for travel or music. Battery is rated up to 35 hours, with a full charge in about 2.5 hours via USB-C and fast-charge support for a quick top-up. Downward-facing RGB adds ambient glow, and one button turns it off entirely.
Buy it if you play on PC, PS5, PS4, Switch or Mac and want low-latency wireless plus a mic your teammates can actually hear. Skip it if you mainly want something to wear in bed — the over-ear shell and boom mic are wrong for pillow use.
The LC-dolida Sleep Mask solves a different problem: listening in the dark without light leaking in and without a headband digging into your skull. It pairs Bluetooth 5.4 with a stated range of up to 15m (about 49 feet) and up to 15 hours of battery. Inside is a high-fidelity 32mm stereo driver that LC-dolida describes as razor-thin — that thinness is the entire engineering trick, because it's what makes the mask wearable for side sleepers instead of pressing a hard lump against your ear.
The mask itself is ice silk on the outside and cotton-filled on the inside, a dual-texture build meant to feel cool on the skin while staying breathable. The light-blocking design is the other half of the story: a semi-wraparound shape, a larger coverage area, triangle wing panels, and a deeper V-shape at the nose that contours around the bridge rather than resting flat across it. That combination is what turns "mostly dark" into total blackout, which matters most in the early morning when light creeps in from the sides and under the eyes.
Fit is handled by a wide cushioned 4.7-inch Velcro strap, adjustable for side, back, and stomach sleepers and for a wide range of head sizes. LC-dolida also includes two noise-cancelling earplugs and a portable storage bag, and positions the mask as a gift for birthdays or holidays.
Buy it if you want music, podcasts, or Bluetooth calls while you fall asleep, and you sleep on your side. Skip it if you need a microphone for team chat or low-latency audio for gaming — this is a sleep and quiet-listening product.
• Best for competitive gaming → EKSA 2.4GHz. The under-30ms 2.4GHz link and game mode are built exactly for that.
• Best for sleeping and side sleepers → LC-dolida Sleep Mask. The razor-thin 32mm driver and ice silk build are designed to be worn lying down.
• Best for battery life → EKSA 2.4GHz. Up to 35 hours versus up to 15 hours, plus fast charge and a 2.5-hour full charge.
• Best for blocking light → LC-dolida Sleep Mask. Total blackout with a contoured nose and wraparound coverage; EKSA does nothing for light.
• Best for voice chat → EKSA 2.4GHz. The noise-cancelling boom mic is the only real microphone in this comparison.
• Best for travel and naps → LC-dolida Sleep Mask. It folds into a small bag with earplugs included; EKSA is a headset you pack as gear.
• Best for multiple devices → EKSA 2.4GHz. 2.4GHz USB, Type-C, Bluetooth 5.4, and a 3.5mm jack cover PC, console, and mobile.
• Best for a gift → LC-dolida Sleep Mask. LC-dolida explicitly builds it as a gift item; a gaming headset is a much more personal pick.
If I had to pick one, I'd buy the EKSA 2.4GHz — but only because I'd be buying it for gaming. It does more jobs: low-latency wireless for competitive play, Bluetooth 5.4 for everyday listening, a real boom mic, 35-hour battery, and a 169g frame that won't wear you down over a long session. In my opinion the LC-dolida Sleep Mask is the better product at exactly one thing, and it does that thing very well: blackout sleep with audio, for side sleepers especially. If sleep is your goal, buy the mask and don't overthink it. If you're a gamer, the EKSA is the one that earns its place on your desk.
EKSA rates up to 35 hours with fast charge and a 2.5-hour full charge via USB-C. LC-dolida rates up to 15 hours. For overnight use, both will cover a full night, but EKSA lasts considerably longer between charges.
Not really. It has Bluetooth 5.4 audio and a thin 32mm driver, but no boom mic, no 2.4GHz low-latency link, and no game mode. It's built for sleep, calls, and quiet listening, not for competitive play.
It's only 169g with breathable mesh earpads, which is light for an over-ear headset, but it's still a full over-ear shell with a boom mic and RGB lighting. For lying on your side, the LC-dolida mask is the far more sensible design.
Both, honestly — and the comparison only makes sense once you've done that. Check the latest price on Amazon for each and weigh it against which job you actually need done: gaming audio or blackout sleep.
