Hivox makes my pick for earbuds rubber and side sleepers: its open-ear hooks avoid a sealed tip while keeping the fit stable. MAcnas is the runner-up if you want newer Bluetooth 5.4 and a battery display.
earbuds rubber at a Glance
• Hivox Open Ear Earbuds — best for open-ear listening during everyday wear; pick this if you want silicone earhooks, Bluetooth 5.3, and an IP54 rating for water and sweat resistance.
• MAcnas Open Ear Headphones — best for workouts and checking charge status; pick this if Bluetooth 5.4 and a case display for battery levels suit your routine.
• ABCPOW Earbuds USB C — best for compatible USB-C devices and a wired connection; pick this if you want in-ear silicone tips in three sizes and a microphone.
• MUMSTHT 50 — best for classrooms and shared listening; pick this if you need a set of wired earbuds with standard 3.5 mm plugs.
Hivox uses an open-ear design with flexible silicone and ergonomic hooks rather than sealing the ear canal with a rubber tip. That distinction makes it my first choice for shoppers looking for earbuds rubber that might be more comfortable when resting on a pillow. The hook keeps the earpiece positioned around the ear, though comfort in bed will depend on how the hook meets your head and pillow.
The open design may appeal to people who dislike the plugged-in feeling of in-ear earbuds. Hivox lists a 16 × 13 mm dynamic driver, a background-noise-cancelling microphone, and voice-capture technology. In daily use, those features point toward listening and calls without putting a sealed eartip into the ear. The listed controls are push buttons, so playback is handled by a physical press rather than a touch surface.
For wireless use, it has Bluetooth 5.3, up to six hours of playback per charge, and up to 30 additional hours with the charging case. Those figures make it a practical option for moving between work, errands, and exercise without relying on a cable. Its IP54 rating indicates water and sweat resistance, a useful specification for active use, but it should not be confused with waterproofing.

MAcnas is another open-ear, over-ear-hook option, aimed at workouts and other active routines. Its open design leaves the ear less enclosed than a conventional in-ear bud, while the hook is intended to keep the earpiece in place. Shoppers comparing open ear headphones for side sleepers may consider it for the same basic reason as Hivox: there is no in-ear tip pressing into the canal. The outer hook can still affect pillow comfort.
Bluetooth 5.4 is the stated wireless version. The case has a digital display that shows the remaining battery levels for the earbuds and case when opened, so it offers a quick charge check without relying only on a phone. Touch controls cover music actions such as playing, pausing, and skipping tracks. That can be convenient during exercise, although some people prefer physical buttons they can locate by feel.
The product information identifies a bone-conduction driver and gives a 20 Hz–20,000 Hz frequency range. It also describes stereo sound and call use, but does not provide a playtime figure or an IP rating. That leaves less concrete guidance for buyers who need to plan long listening sessions or want a stated sweat-resistance specification. The adaptive noise-control listing also deserves caution: the open-ear design is not a sealed fit, so it should not be read as a promise of strong isolation.
I would consider MAcnas if Bluetooth 5.4 and the visible battery display matter more to you than a listed water-resistance rating or clearly stated battery duration. For side sleeping, the open fit is a potential advantage over silicone in-ear tips, but the over-ear hook remains a possible pressure point. Its strongest fit is likely someone who wants open-ear headphones for daytime activity and easy battery checking.
ABCPOW takes a different route: these are wired, in-ear earbuds that connect through USB-C. They include silicone eartips in small, medium, and large sizes, so the buyer can choose among three tip options. That gives them a more conventional rubber-tip fit than the two open-ear models, which may be welcome for sound isolation but less comfortable for a side sleeper whose ear is pressed against a pillow.
A wired connection means no Bluetooth pairing or charging routine. The product information lists a dynamic driver, a 20 Hz–20,000 Hz frequency range, push-button controls, and sound isolation. A microphone is included in the product title, but compatibility notes caution that some devices may support music playback without phone calls. Buyers should check the capabilities of their particular USB-C device rather than assume every function works across all models.
The stated compatibility is for USB-C devices without a 3.5 mm audio port. That includes listed phone families and other compatible devices, but the fit is not universal across every USB-C port: the product notes that some devices may not support call functionality. It also advises checking the volume control or another port if there is no sound. Those details matter if you are buying for a specific phone, tablet, or computer.
I’d choose ABCPOW when a direct wired connection and in-ear sound isolation are priorities. It is not a strong match for someone specifically seeking the best sweat resistant in ear headphones for side sleepers: the supplied facts do not state a water-resistance rating, and an in-ear tip may press against the pillow. The three tip sizes offer some fit choice, but they do not remove that basic trade-off.
MUMSTHT is a bulk set of 50 wired in-ear earbuds with standard 3.5 mm plugs. The product is aimed at classrooms, libraries, and other shared settings, where having many simple listening sets can be more useful than wireless features. The soft silicone eartips are described as comfortable, but no tip-size options are specified.
Each set connects through a 3.5 mm jack and has no wireless capability. The published details say there is no built-in microphone. The listing mentions media control, but does not spell out exactly which functions are available, so I would not choose these for calls or assume advanced playback controls. Their strongest practical advantage is the straightforward wired connection on devices that have a compatible headphone jack.
For a school or group setting, a large quantity of simple earbuds can make sense. For an individual shopper, though, the 50-piece pack may be more than needed, and a 3.5 mm connection will not suit a device without that port unless the user has a compatible adapter. The in-ear form also puts a tip in the ear, which may be uncomfortable for some side sleepers.
I would treat MUMSTHT as a classroom-focused option rather than a personal bedtime pick. It covers a different need from Hivox and MAcnas: many basic wired sets, not open-ear wireless listening. The lack of a microphone and the fixed 3.5 mm connection are meaningful limitations for people who want calls or modern port flexibility.
We compared the published design, connection, comfort-related features, and other listed specifications for each product.
The order is our independent editorial opinion based on how well each fits the stated use cases.
No brand paid for placement.
They avoid an eartip sitting inside the ear, which may be preferable if an in-ear bud feels intrusive. However, both open-ear picks use earhooks that may press against a pillow, so comfort will depend on your sleeping position and fit.
Hivox lists an IP54 rating for water and sweat resistance. The supplied details for the other three products do not state an equivalent rating, so I would not assume they have one.
Yes. ABCPOW connects by USB-C, while MUMSTHT uses a 3.5 mm audio jack. Both require a compatible device port; Hivox and MAcnas connect wirelessly through Bluetooth.
I recommend Hivox for side sleepers who want to avoid an in-ear rubber tip, because its open-ear design and silicone hooks offer a different fit approach. The hook may still touch the pillow, so it is not a guaranteed fit for every sleeper.
