• Sony MDRZX750BN — biggest strength: Digital noise cancelling that reduces ambient noise up to 98%, plus 40mm drivers, Bluetooth with NFC pairing and up to 13 hours of music playback.
• Sony MDRZX750BN — biggest trade-off: It is a conventional over-ear headphone weighing 1.3 pounds with no audio jack, so it is bulky for bed and useless for wired listening.
• Fulext Sleep Headphones Headband — biggest strength: A 3-in-1 sleep mask, headphone and sports headband with ultra-thin speakers built to avoid ear pressure when you lie on your side.
• Fulext Sleep Headphones Headband — biggest trade-off: It isolates sound rather than cancelling it, and its 12-hour battery is shorter than the Sony's 13 hours.
• Who each pick is for: Sony for commuters, travelers and home listeners who want serious noise reduction; Fulext for sleepers, side sleepers, runners and anyone who wants audio without anything hard pressing on their ears.
The Sony MDRZX750BN is built around one idea: shut the world out. Its digital noise cancelling circuitry automatically picks one of three modes based on the ambient noise around you, and Sony rates the reduction at up to 98%. That is the headline feature, and it is the reason this headphone exists. Large 40mm dynamic drivers cover a full 20–20,000 Hz range wirelessly, and when you plug in the supplied audio cable the Beat Response Control design pushes the range down to 8 Hz for tighter, deeper bass. If you care about low-end punch, that passive mode is the one to use.
Connectivity is where the Sony shows its age and its convenience at once. Bluetooth 3.0 with NFC lets you tap compatible devices together to pair or unpair, and AAC and aptX codec support means wireless streaming keeps more of your file quality than plain Bluetooth would. Range is around 10 meters, which is fine for walking around a room but not for wandering a whole house. There is also a built-in microphone for hands-free calls, and media controls on the headset itself. The ear pads are leather with a swivel design, and the outer shell and headband mix metal and plastic. Charging takes about 2 hours for up to 13 hours of music, and you can run it in passive mode without draining the battery at all — a genuinely useful fallback.
Buy it if you commute, fly, or work in a noisy room and want active noise cancellation, wireless freedom and strong bass from a proper over-ear design. Skip it if you want to wear headphones in bed, need a wired connection (there is no headphone jack), or want the lightest possible thing on your head — at 1.3 pounds this is a substantial headphone.
The Fulext Sleep Headphones Headband solves a completely different problem. It is three products in one: a sleep mask, a pair of sleep headphones, and a Bluetooth sports headband. The trick is the ultra-thin HD stereo speakers nestled inside padded earpieces. There is no hard shell, no clamping band, no pressure point — which is exactly what makes it work for side sleepers, who normally cannot wear anything over their ears in bed.
The electronics are current rather than retro: Bluetooth 5.4, a rechargeable lithium battery rated for over 12 hours, and a fast 2–2.5 hour charge. That means it lasts a full night of sleep sounds or a long stretch of workouts. The fabric is soft, hypoallergenic spandex with a breathable, sweatproof design, and the whole band is machine washable once you remove the control pod — the electronic module pops out so the fabric can be cleaned. The frequency range is 20 Hz–20,000 Hz, matching the Sony's coverage on paper, delivered through balanced armature drivers. Noise control is sound isolation rather than active cancellation, so it muffles a snoring partner or cabin hum but does not erase it the way the Sony does.
The use cases are broad and specific at the same time: napping, airplane travel, the gym, running, yoga, meditation, and blocking out snoring. The controls are touch-based, and it ships with the headband, a user manual and a wireless charging case. Fulext backs it with a 2-year warranty. At 3.2 ounces it is less than a fifth of the Sony's weight, and it comes in Linen Purple.
Buy it if you want to fall asleep to audio, share a bed with a snorer, or need headphones that stay put and stay comfortable during sweaty workouts. Skip it if you want true noise cancellation for a loud commute, or you want the bass weight and driver size of a full over-ear headphone.
Side-by-Side: Which Should You Choose?
• Best for noise cancellation → Sony MDRZX750BN. Up to 98% ambient noise reduction with three automatic modes; the Fulext only isolates sound.
• Best for long listening sessions → Sony MDRZX750BN, narrowly. Up to 13 hours versus 12+ hours, and the Sony can also run passively with no battery at all.
• Best for workouts and running → Fulext Sleep Headphones Headband. Sweatproof, breathable spandex that stays on your head; the Sony's 1.3-pound over-ear frame is not made for that.
• Best for call quality and media controls → Sony MDRZX750BN. A built-in microphone and dedicated media controls make it the more complete headset.
• Best for easy maintenance → Fulext Sleep Headphones Headband. Machine washable fabric with a removable control pod.
• Best for modern wireless pairing → Fulext Sleep Headphones Headband. Bluetooth 5.4 versus Bluetooth 3.0, though the Sony compensates with NFC one-touch pairing.
• Best for bass and full-size sound → Sony MDRZX750BN. 40mm dynamic drivers with Beat Response Control and an 8 Hz low end in wired mode.
In my opinion, these two are not really rivals — they are answers to different questions, and the right pick depends on where you will wear them. If I wanted one pair of headphones to commute, travel and concentrate with, I would buy the Sony MDRZX750BN, because real active noise cancellation, larger drivers and a 13-hour battery are things a fabric headband simply cannot match. If I wanted to fall asleep to audio or wear headphones through a workout without anything digging into my ears, I would buy the Fulext Sleep Headphones Headband without hesitation. If you truly need both jobs done, buy both — they cover each other's weaknesses almost perfectly. Check the current price on Amazon before deciding, since that is what usually tips the scale between a full-size headphone and a sleep band.
Yes. The Fulext is designed specifically for it, with ultra-thin speakers inside padded earpieces so there is no pressure on your ears when you lie on your side. The Sony is a 1.3-pound over-ear headphone with a rigid headband, which is uncomfortable in bed.
Yes, and it is not close. The Sony uses digital active noise cancellation rated at up to 98% ambient noise reduction with three automatic modes. The Fulext relies on passive sound isolation, which muffles noise but does not cancel it.
The Sony MDRZX750BN is rated for up to 13 hours of music and charges in about 2 hours. The Fulext is rated for over 12 hours and charges in 2–2.5 hours. The gap is small, but the Sony also lets you keep listening in passive mode with the cable once the battery is empty.
Yes. It is made from breathable, sweatproof spandex and doubles as a sports headband, so it stays in place during running, yoga and workouts. The Sony's over-ear design is not intended for that kind of activity.
