How We Research
We compare products from their published specs and features; the verdicts below are our independent editorial opinions.
If you want long battery life and a proper over-ear headphone you can wear all day for music, calls and travel, choose LORELEI B-C6; if you need something to wear in bed to block light and play quiet audio while you fall asleep, choose Perytong Sleep Mask.
• LORELEI B-C6 — biggest strength: a 500mAh battery rated for up to 50 hours of playback, plus a 3.5mm cable option so you can keep listening even when the battery runs down.
• LORELEI B-C6 — biggest trade-off: it's a full-size over-ear headphone at 205 g with sound isolation only (no active noise cancelling), so it's not something you'd comfortably sleep in.
• Perytong Sleep Mask — biggest strength: a true 2-in-1 design that combines a blackout 3D-contoured eye mask with ultra-thin Bluetooth 5.4 speakers, built specifically for side sleepers and bedtime listening.
• Perytong Sleep Mask — biggest trade-off: around 12 hours of playtime per charge and no wired fallback, so it's a night-time and nap device, not an all-day music headphone.
• Who each pick is for: LORELEI B-C6 for commuters, students, home-office users and anyone who wants one headphone for music and calls; Perytong Sleep Mask for side sleepers, light-sensitive sleepers, meditators and frequent flyers.
The LORELEI B-C6 is a conventional wireless over-ear headphone, and it's built around one clear idea: keep the music going. The 500mAh battery is rated for up to 50 hours of playback on a single charge, which is a genuinely long window — enough that most people won't be thinking about charging every couple of days. When the battery does run low, you can plug in the included 3.5mm braided cable and keep listening, which is a nice safety net that a lot of wireless headphones in this style skip entirely.
Sound-wise, it uses dual 40mm dynamic drivers with a 20 Hz–20,000 Hz frequency range, 32 ohm impedance and 110 dB sensitivity, tuned for what LORELEI calls deep bass. On paper that's a standard full-range setup, and the low impedance and high sensitivity mean it should be easy to drive from a phone or laptop without pushing the volume. Bluetooth 5.3 handles the wireless side with a 10-metre range, and there's a built-in microphone for calls plus touch controls on the earcup for media.
Who should buy it: anyone who wants one headphone for commuting, studying, gaming, home-office calls and travel, and who values long battery life over absolute portability. The adjustable headband also means it can be shared between adults and kids.
Who should skip it: if your main goal is sleeping with audio on, this isn't the tool. It's an over-ear headphone with sound isolation rather than active noise cancelling, and at 205 g with full-size earcups it's designed for sitting, walking and travelling — not for rolling over on a pillow.
Perytong Sleep Mask: Who It's For
The Perytong Sleep Mask attacks a completely different problem. It's a 2-in-1: a sleep mask and a pair of wireless sleep headphones fused into one wearable band. The ultra-thin speakers sit over your ears without pressing on them, which is the whole point — no earbuds digging in when you lie on your side, and no separate mask and headphone to juggle.
The eye side is where it earns its keep. The 3D contoured eye cups are shaped to keep pressure off your eyelids and lashes, and Perytong claims 100% blackout for deeper sleep. If you're sensitive to ambient light — streetlights, a partner's reading lamp, early summer sun — that's the feature you're actually buying. An adjustable velcro strap tightens it to your head size so it stays put through the night.
On the audio side it runs Bluetooth 5.4, the newer of the two chipsets in this comparison, for fast, stable pairing with phones, tablets and laptops. Sound is described as HD stereo, which is plenty for sleep music, ASMR, meditation guides, audiobooks and white noise — this is a device for quiet, close listening, not for critical music listening. There's a built-in microphone for hands-free calls too, so it doubles as a home-office headset in a pinch.
Battery is rated at 12+ hours of continuous playback with USB-C charging, and the low-power design is aimed at getting you through a night. The control buttons sit in the middle of the band so you can adjust without taking the mask off. Materials are premium memory foam plus skin-friendly cotton, and the whole thing is machine-washable once you remove the control module — a real practical win, since anything worn on your face every night gets grimy. It ships with a USB-C cable and a travel pouch, and it folds down for flights, camping, yoga nidra and office power naps.
Who should buy it: side sleepers, light-sensitive sleepers, people who fall asleep to audio, meditators, and frequent flyers who want one item in the bag instead of three.
Who should skip it: if you want headphones for music during the day, calls on the move, or long listening sessions away from a charger, the 12-hour rating and mask-first design will frustrate you. It also has no wired option and no noise cancelling.
• Best for battery life → LORELEI B-C6. Up to 50 hours versus 12+ hours is not a close contest.
• Best for sleeping and side sleepers → Perytong Sleep Mask. The 3D contoured eye cups and ultra-thin speakers are designed for exactly that; the LORELEI isn't.
• Best for blocking light → Perytong Sleep Mask. 100% blackout is the core feature. The LORELEI only offers sound isolation, not light blocking or active noise cancelling.
• Best for music quality and volume → LORELEI B-C6. Dual 40mm dynamic drivers with a 20 Hz–20,000 Hz range and deep-bass tuning are built for actual listening.
• Best for travel during the day → LORELEI B-C6. It folds to roughly 6.7 × 5.6 × 3.15 and comes with a leather carry pouch.
• Best for travel at night → Perytong Sleep Mask. It's lighter, foldable, comes with a travel pouch, and is machine-washable after a long flight.
• Best for wired backup → LORELEI B-C6. The 3.5mm jack means you're never fully dependent on the battery.
• Best for newer Bluetooth → Perytong Sleep Mask. Bluetooth 5.4 versus Bluetooth 5.3 — a small edge in pairing stability, though both are current-generation chips.
In my opinion, the LORELEI B-C6 is the better buy for most people, because it's the more versatile device. It plays music properly with 40mm drivers, handles calls, folds small enough for a bag, lasts up to 50 hours, and gives you a wired fallback when the battery dies. That covers commuting, study, work and travel in one purchase. I'd only steer you to the Perytong Sleep Mask if sleep is the specific job — if you're a side sleeper, you're bothered by light, or you drift off to audio every night, its 3D eye cups, 100% blackout design and washable memory-foam build solve a problem the LORELEI simply wasn't made for. If you can only justify one, pick based on whether you need a headphone or a sleep aid.
Yes. The Perytong is purpose-built for it: 3D contoured eye cups, 100% blackout, ultra-thin over-ear speakers and a velcro strap for a non-slip fit. The LORELEI is a 205 g over-ear headphone with sound isolation, which isn't designed to be worn against a pillow.
I don't publish prices here because they change often. Check the current price on Amazon using the button on this page before you decide — both sit in the budget-to-mid range for their categories, but the gap between them shifts.
The LORELEI B-C6, by a wide margin. It's rated for up to 50 hours on its 500mAh battery and can run on a 3.5mm cable when empty. The Perytong is rated for 12+ hours of continuous playback, which is aimed at covering a night rather than a week.
Both have built-in microphones, so calls work on either. For meditation, the Perytong is the more natural fit because the thin speakers and blackout mask let you lie down comfortably with a guided audio track. The LORELEI works for seated meditation but isn't built for lying on your side.
