If you want feature-rich listening for commutes, workouts, and calls, choose QXUFV Earbuds; if you need a low-profile fit for side sleepers, choose Mudtun Sleep Earbuds Ultra-Thin. For bedtime comfort, Mudtun’s curved, ultra-thin design is the more focused choice; for noise control, touch-screen case functions, and longer total playback, QXUFV offers more versatility.
QXUFV Earbuds vs Mudtun Sleep Earbuds Ultra-Thin at a Glance
• QXUFV Earbuds strength: Active noise cancellation, transparency mode, five EQ modes, and a feature-packed charging case. Trade-off: Their in-ear design is less specifically suited to lying on your side.
• QXUFV is for listeners who want one pair for music, calls, travel, and exercise, with a reported 48 hours of total playback using the case.
• Mudtun is for bedtime listening, naps, and anyone who prioritizes a less intrusive fit over noise-cancelling features.
• My quick pick for side sleepers: Mudtun. My pick for a more versatile everyday pair: QXUFV.
QXUFV Earbuds make more sense as all-purpose wireless headphones than as sleep earbuds. Their in-ear design combines active noise cancellation with a transparency mode that brings surrounding sound forward. That gives you two different ways to manage your surroundings: reduce ambient noise when you want to focus, or hear more of what’s around you when awareness matters. The product also lists ENC for reducing background noise during calls.
For music, QXUFV includes five EQ options—Standard, Classic, Jazz, Rock, and Pop—and a 13 mm graphene driver. The case adds functions beyond charging: its touchscreen controls include options such as setting a timer, adjusting brightness, changing the wallpaper, and activating a flashlight. There are also touch controls on the earbuds. If you like having playback and extra utilities close at hand, that mix is a real point in QXUFV’s favor.

Mudtun is the more purpose-built option for bedtime. Its curved, low-profile shape is designed to sit along the ear contour, and the maker describes the fit as non-in-ear, with the aim of avoiding the deep-canal feel. That design is especially relevant for side sleepers, since an earbud that sticks out more can press against a pillow. The product is also pitched for small ears, though a listed fit description cannot guarantee comfort for every person.
The controls suit quiet, hands-on adjustments. Mudtun uses physical buttons rather than touch controls, which are intended to reduce accidental presses while sleeping. It also specifies no low-battery beeping. For winding down, its sound adjustments include multiple bass levels, and the intended listening includes white noise, ASMR, audiobooks, podcasts, and relaxing music. These are practical bedtime details; they do not make the earbuds noise-cancelling.
That distinction matters. Mudtun uses passive noise blocking from its fit and acoustic seal, and it does not include ANC. Its stated playback is about five to six hours, with a charging case for extra power and an LED display to check remaining battery. I’d choose it for sleep, naps, or travel when a low-profile fit is the priority. I’d pass if I wanted active noise reduction, a transparency mode, or the broader controls and exercise-oriented features listed for QXUFV.
Side-by-Side: Which Should You Choose?
• Best for side sleepers → Mudtun Sleep Earbuds Ultra-Thin. Its ultra-thin, curved design is specifically intended to reduce pressure while lying on your side.
• Best for hearing more of your surroundings → QXUFV Earbuds. Its transparency mode is designed to amplify outside sounds.
• Best for bedtime controls → Mudtun Sleep Earbuds Ultra-Thin. Physical buttons are designed to help avoid accidental touch inputs, and the product specifies no low-battery beeping.
• Best for longer stated total playback → QXUFV Earbuds. QXUFV lists up to 48 hours with the case, while Mudtun describes roughly five to six hours per charge and extra case power without a matching total-playback figure.
• Best for exercise and wet-weather use → QXUFV Earbuds. Its listed IPX7 rating and in-ear fit are more suited to sweat and rain than Mudtun’s sleep-first design.
• Best for a focused bedtime sound profile → Mudtun Sleep Earbuds Ultra-Thin. Its adjustable bass levels and stated use for white noise, ASMR, and spoken audio are aimed at quiet listening.
• Best for EQ variety and case functions → QXUFV Earbuds. It lists five EQ modes and a touchscreen case with added utilities.
A few tempting search phrases need a reality check. If you’re looking for spatial audio on ear headphones for side sleepers, neither product’s supplied specifications identify spatial audio, and neither is described as an on-ear headphone. Mudtun is still the clearer fit for sleeping on your side because its low-profile design is the deciding feature—not a claim about spatial sound.
Likewise, neither product is described as bone-conduction hardware, so I wouldn’t call either the best bone conduction headphones for side sleepers. And although QXUFV lists a 13 mm driver, five EQ modes, and HiFi stereo sound, that alone does not establish it as the best hifi stereo open ear headphones for side sleepers. It is an in-ear design; Mudtun is the one explicitly shaped around sleep comfort.
My Verdict
I’d choose QXUFV instead if I wanted ANC, transparency mode, more EQ choices, and a feature-rich case for everyday listening.
For sleep first, Mudtun is my recommendation; for one pair to cover more situations, QXUFV is the more versatile pick.
Mudtun is the more sleep-focused choice. Its ultra-thin, curved design is intended to minimize pressure when lying on your side. QXUFV has an ergonomic in-ear design, but its listed features don’t specifically target pillow comfort.
No. Mudtun uses passive noise blocking and does not include active noise cancellation. QXUFV lists ANC as well as a transparency mode.
QXUFV states six to eight hours of playback per charge and up to 48 hours with its charging case. Mudtun states about five to six hours of continuous playback per charge and describes extra power from its case, but does not provide the same total-playback figure.
Mudtun is presented for white noise, ASMR, audiobooks, podcasts, and relaxing music, with adjustable bass levels and physical controls. QXUFV can also play audio, but its listed features are broader and more focused on general listening, calls, and noise control.
