For side sleepers, the Oaxis myFirst Kids is my pick for the best lightweight wireless headphones for side sleepers because its open-ear design avoids a sealed earcup. Wentronic is the runner-up for long battery life and noise cancelling, but its over-ear cushions may press against a pillow.
best lightweight wireless headphones for side sleepers at a Glance
• Wentronic Y04 — best for travel and noise reduction; pick this if you want active noise cancelling, foldability, and up to 48 hours of battery life.
• Generic Open-Ear Headphones — best for compact carry; pick this if you want lightweight earbuds, a charging case, and Bluetooth 5.4.
• Wentronic Y04 — best for listeners who prefer grey; pick this if its over-ear design, active noise cancelling, and 3.5 mm jack suit your routine.
• Wentronic Y04 — best for listeners who prefer pink; pick this if you want the same 48-hour battery claim and foldable design in that color.
• Wentronic Y04 — best for listeners who prefer starlight; pick this if you want the same core features with a 3.5 mm connection option.
The Oaxis myFirst Kids is an open-ear, air-conduction wireless headphone designed for children ages 3–12. Its most relevant feature for sleeping is what it leaves out: there are no over-ear cups enclosing the ears. At 21.5 g, it is also notably light on paper. That makes it the most plausible choice here for someone who wants to avoid bulky headphones, although it is a kids’ product rather than an adult sleep-specific model.
Open-ear listening keeps the ear less isolated from nearby sound. That can be useful if you want to hear a partner, an alarm, or activity around the room instead of being sealed off. Bluetooth 5 and a stated 18-hour battery life also make it suitable for ordinary listening across a day, while USB-C fast charging is a practical detail when it needs topping up. Simple button controls should be easier to operate than a complicated touch interface.
The 85 dB volume cap is a defining feature for its intended young listeners. It is not a reason to assume the headphones are suitable for every child or every listening situation, but it does set a ceiling on output. IPX5 water resistance gives it a more everyday, active-use profile than a delicate sleep accessory. The trade-off is that an open-ear design does not provide the isolation of noise-cancelling headphones, and its kid-focused fit may not suit every adult. For a side sleeper, I would consider it only if the band and contact points can sit comfortably without being pushed into the pillow.

The Wentronic Y04 is a foldable, over-ear Bluetooth headphone with active noise cancelling, soft cushions, and a stated battery life of up to 48 hours. It is aimed at adult listeners who want an all-purpose pair for travel, work, and long listening sessions. Bluetooth 5 supports wireless use, and a 3.5 mm jack provides a wired connection option. The grey version has the same listed core design and features as the other Y04 variants.
Its noise cancelling may make it a better fit than an open-ear model for reducing surrounding sound while sitting on a plane or working in a shared space. The foldable build is also easier to pack than a rigid, non-folding headset. A two-hour charge time and long stated runtime reduce how often it needs to be connected to power, though battery figures are manufacturer specifications, not a guarantee for every listening pattern.
For sleeping on your side, the main question is physical bulk. This is an over-ear design with padded cushions, so a pillow could press the earcup against the side of the head. The cushions may be comfortable during upright listening, but that does not establish comfort when lying down. I would choose the Y04 over the Oaxis only when blocking outside noise and long battery life matter more than minimizing pressure near the ear.
The Generic Open-Ear Headphones are compact wireless earbuds with ear hooks, a charging case, and Bluetooth 5.4. Each earbud is listed at 0.14 oz, which makes the individual pieces lighter than a conventional over-ear headphone. The case includes a display for battery and charging status. This set may appeal to someone who wants a small option for commuting, exercise, or carrying in a pocket.
The description also lists active noise reduction, a transparency mode, in-ear detection, and microphones for calls. Those features point to a multipurpose earbud rather than a simple sleep device. The stated continuous use is six to eight hours per charge in the feature description, while the product details list six hours of average battery life. I would plan around the more conservative figure. The charging case helps extend use between outlets, but the supplied specifications do not give a combined runtime figure that I would rely on.
There is an important fit distinction for side sleepers: despite the open-ear wording in its name, the product details identify the placement as in-ear and describe earplugs. The hooks may help keep the earbuds positioned during movement, but an in-ear body can still create pressure when a pillow pushes against it. This is not the same low-contact approach as an open-ear air-conduction headset. If you are looking for the best wireless earbuds for side sleepers, the lightweight build is promising, but I would treat pillow comfort as uncertain based on the listed design.
The grey Wentronic Y04 is another color version of the same foldable over-ear model. Its listed features include active noise cancelling, soft ear cushions, Bluetooth 5, a 3.5 mm jack, and up to 48 hours of battery life. The 40 mm drivers and button controls make it a conventional full-size headphone option for everyday audio rather than a purpose-built sleep band or tiny earbud.
For travel, the combination of folding hinges and a wired fallback is useful: you can pack the headphones and still connect through the jack when wireless use is not convenient. The active noise cancelling is the standout feature for someone who needs less ambient sound during a commute or focused listening. It also has a two-hour charge time according to the specifications.
The same limitation applies at bedtime. These are over-ear headphones with cushions, so the earcups occupy the area most likely to meet the pillow. The grey version does not list a different fit or sleep-oriented feature that would change that concern. I would select it for noise control and general listening, not because the color variation makes it more suitable for lying on one side.
The pink Wentronic Y04 shares the same main specification set: foldable over-ear construction, Bluetooth 5, active noise cancelling, soft cushions, a 3.5 mm jack, and a stated 48-hour runtime. Its distinguishing detail in the supplied information is the color. For someone already looking for a conventional over-ear headset and who prefers pink, it offers the same basic use case as the other Y04 options.
That makes the buying decision straightforward. Its long claimed battery life suits extended listening between charges, while folding helps with storage and travel. Button controls are simple in concept, and the wired jack offers another way to connect. These are practical features for use at a desk, on a trip, or around the house.
For side sleeping, however, a color choice does not address the physical issue. The padded earcups may be comfortable when sitting upright, but a pillow can press them into the head. I would not call this a strong choice for anyone whose priority is avoiding ear pressure overnight. It is a better fit for a shopper who wants a foldable ANC headphone and plans to listen while upright.
Wentronic Y04
The starlight Wentronic Y04 has the same listed over-ear format and core features as the grey and pink versions. It folds for carrying, connects over Bluetooth 5, includes a 3.5 mm jack, and is specified with active noise cancelling and up to 48 hours of battery life. The supplied details do not indicate a different shape or comfort feature for this color variant.
Its appeal is therefore the familiar Y04 combination: substantial ear cushions for seated listening, noise reduction for busy surroundings, and a wired option alongside wireless playback. A stated two-hour charging time is useful to know when planning around a depleted battery. For anyone comparing the color versions, the decision is mainly about appearance rather than a documented difference in fit or function.
That consistency also means the same side-sleeping caveat remains. An over-ear cup is likely to take up more space between the ear and pillow than a compact, low-profile design. I would pick this version for general listening if the starlight finish is the preference, but not as a dedicated answer to overnight pressure.
I compared the published design, connectivity, battery, and comfort-related features for each listed product. The ranking is my independent editorial opinion, based on how those details may fit side sleeping and everyday listening. No brand paid for placement.
They can be comfortable for upright listening, but an over-ear cup may press against the pillow when you lie on your side. The Wentronic Y04 has padded cushions, but its specifications do not describe a sleep-specific low-profile design.
They may avoid enclosing the ear, which can reduce one source of pressure, but fit still matters. The Oaxis myFirst Kids is lightweight and open-ear, though its intended audience is children and the listed details do not establish adult sleep comfort.
The Oaxis is the clearest open-ear design in this comparison, but it is a headphone rather than an earbud and is designed for kids. The Generic model is compact and rechargeable with a case, but its product details describe an in-ear fit.
The Generic model has ear hooks, but the specifications identify it as in-ear rather than a low-profile clip-on design. An ear hook may help with positioning, yet it does not guarantee that the earbud will feel comfortable against a pillow.
My final recommendation for side sleepers is the Oaxis myFirst Kids, because its light, open-ear construction avoids bulky over-ear cups; choose it only if its child-sized design suits you.
