If you want wired, closed-back headphones for focused listening and everyday audio, choose Superlux HD660PRO; if you need a wireless headband for sleep, workouts, or hands-free calls, choose LC-dolida Sleep Headphones. For commuting, I’d choose the Superlux for a conventional headphone setup; the LC-dolida makes more sense if a soft, wearable headband matters more than studio-style listening.
They serve very different needs. The choice is less about which one does the same job better and more about whether you want traditional wired headphones or a Bluetooth headband that can also cover your eyes.
Superlux HD660PRO vs LC-dolida Sleep Headphones at a Glance
• LC-dolida Sleep Headphones: A Bluetooth 5.4 headband with thin speakers, a sleep-mask design, and up to 15 hours of playback; it does not use a headphone jack.
• For a regular commute: Superlux has the more familiar headphone format, while its wired design means you’ll need to manage an 8.2-foot cable.
• For rest or light activity: LC-dolida combines audio with a wearable headband, but its fabric-and-speaker design is not a conventional over-ear headphone.
• Choose Superlux for wired listening across mobile devices and studio-style equipment; choose LC-dolida for sleep, exercise, and wireless convenience.
The Superlux HD660PRO is a conventional over-ear headphone built around a closed-back design and 40 mm dynamic drivers. Its listed frequency range is 10 Hz to 30 kHz, and its 32-ohm impedance is suited to use with devices such as smartphones, tablets, and laptops, as well as compatible studio gear. That makes it a flexible option for someone who wants one wired pair for music, spoken audio, or creative work.
For commuting, its strengths are straightforward: it has a standard 3.5 mm plug, and a 6.3 mm adapter is included for compatible audio equipment. The closed-back design gives it a more focused, traditional listening format than a fabric headband with thin speakers. The trade-off is the cable. At 8.2 feet, it offers reach around a desk or studio setup, but that length can be awkward when walking, boarding transit, or stowing the headphones between stops. The product sheet lists no noise-control feature, so I would not choose it on the assumption that it actively reduces outside sound.
How We Research
We compare products from their published specs and features; the verdicts below are our independent editorial opinions.
The adjustable headband, swivel ear cups, and velvet ear pads point to a fit that can be adjusted for longer listening sessions. The leather headband and over-ear shape also make it a more substantial choice than a soft sleep band. It includes a storage pouch, and its 3.5 mm connection keeps it simple to connect without Bluetooth pairing or battery charging.
Who should skip it: Skip the Superlux if you want wireless listening, a compact sleep mask, or a headband that stays in place during exercise without a dangling cable.
The LC-dolida Sleep Headphones take a different approach: the audio components sit inside a stretchable headband, which is also intended to work as a sleep mask and sports headband. The speakers are described as 0.25-inch thin, and the unit connects over Bluetooth 5.4. It includes a microphone for hands-free calls and has button-based media controls. If you want a wearable audio option for winding down, yoga, or a workout, this combination may be more relevant than a set of conventional headphones.
The battery is listed for up to 15 hours of playback, with a charging time of about two hours. That avoids the need to plug in during each listening session, though it does mean the headband needs to be charged. Its wireless connection is listed with a range of 15 meters. The design also uses elastic, breathable, sweat-wicking material, and the speaker components can be removed so the headband can be washed. Those details give it a practical role for sleep and exercise that the Superlux does not try to fill.
For commuting, the LC-dolida may appeal if you prefer a soft headband and wireless listening over a traditional over-ear fit. But this is not a typical headphone design aimed at focused, detailed listening. Its listed frequency range is 20 Hz to 20,000 Hz, and its speakers are built to sit within fabric rather than form a padded over-ear enclosure. It also has no headphone jack, so it depends on Bluetooth and its battery.
Who should skip it: Skip the LC-dolida if you want wired connections, a conventional over-ear headphone fit, or a product intended primarily for a studio-style setup.
• Best for a wired commute → Superlux HD660PRO. Its 3.5 mm plug connects directly to compatible devices, but the 8.2-foot cable may take some managing on the move.
• Best for wireless commuting → LC-dolida Sleep Headphones. Bluetooth 5.4 removes the cable, but you’ll need to keep its battery charged.
• Best for a studio or desk setup → Superlux HD660PRO. The included 6.3 mm adapter expands its connection options beyond the standard 3.5 mm plug.
• Best for sleeping or wearing as a mask → LC-dolida. Its headband is designed to double as a sleep mask, and the speakers are thin.
• Best for sweat-oriented activity → LC-dolida. Its breathable, sweat-wicking fabric and headband format are intended for exercise and movement.
• Best for adjusting the fit of traditional headphones → Superlux. It has an adjustable headband and swivel ear cups, unlike the fabric-band format of the LC-dolida.
• Best for listening without a battery → Superlux. Its wired design does not rely on a built-in playback battery.
• Best for hands-free calls → LC-dolida. The headband includes a microphone and supports answering calls over Bluetooth.
Buying Considerations
Think first about how you want the audio to connect. The Superlux is wired and has both a 3.5 mm plug and a 6.3 mm adapter. It does not require Bluetooth pairing, but the long straight cable is a real consideration if your commute involves walking or crowded transit. Check whether your usual listening device has a compatible headphone connection before choosing it.
The LC-dolida removes the cable from the listening setup, but its wireless convenience comes with battery upkeep. The listed playback time is up to 15 hours, and charging takes about two hours. Its Bluetooth range is listed as 15 meters, although the practical connection in any setting can depend on the surroundings and paired device. It has no headphone jack.
Next, consider what “comfort” means for your routine. The Superlux has an adjustable over-ear fit, swivel cups, and velvet ear pads, which suit someone who wants a familiar headphone shape. The LC-dolida uses an elastic, breathable headband that can serve as a sleep mask and sports accessory. Those are different kinds of wear, not interchangeable versions of the same design.
Finally, be clear about the listening features you need. Neither product lists a noise-control feature. The Superlux’s closed-back construction describes its headphone design, but that should not be confused with a listed active noise-cancelling function. The LC-dolida’s sleep-mask role and thin speakers make it specialized for wearable convenience, not a substitute for a conventional studio headphone.

In my opinion, I’d buy the Superlux HD660PRO for a commute if I wanted a traditional over-ear headphone with a wired connection and the option to use it with compatible studio gear. Its long cable is a compromise, but the 40 mm drivers, adjustable fit, and included adapters make its role clear.
I’d choose the LC-dolida Sleep Headphones instead for sleeping, workouts, or wireless hands-free calls. For my commuting pick, though, I prefer the more conventional listening setup of the Superlux—as long as the cable suits the route.
For a wired, conventional headphone setup, the Superlux is the clearer fit. The LC-dolida is the wireless option and may suit someone who prefers a soft headband, but it needs charging and has no headphone jack.
The product sheet lists wireless Bluetooth connectivity and no headphone jack. It is therefore designed to connect wirelessly rather than through a wired headphone connection.
Its listed playback time is up to 15 hours, and its charging time is about two hours. Actual use can vary, so those figures are best treated as product specifications rather than a guarantee for every listening session.
Neither product lists noise control, and neither is described as using bone conduction. The Superlux is a closed-back, wired over-ear headphone; the LC-dolida uses thin speakers built into a Bluetooth headband.
