If you want compact wired in-ear headphones with an acoustic seal, choose Allen & Heath Xone:XD-20; if you need wireless over-ear headphones with active noise cancellation, choose Sony WH-XB910N. For side sleepers, the Xone’s in-ear design is the more plausible fit, while the Sony’s larger ear cups bring useful wireless features for travel and everyday listening.
Allen & Heath Xone:XD-20 vs Sony WH-XB910N at a Glance
• Sony WH-XB910N strength: Bluetooth, active noise cancellation, and up to 30 hours of battery life; trade-off: over-ear cups may be awkward against a pillow.
• The Xone is the more natural candidate for someone who wants a small earpiece and does not need wireless listening.
• The Sony is for someone who values wireless convenience, noise cancellation, and adjustable sound presets.
• For side sleepers, I would start by considering the Xone’s in-ear design, but fit and comfort still depend on the individual.
The Xone:XD-20 is a wired in-ear headphone with a 3.5 mm jack and a 13.6 mm driver. Its acoustic seal is intended to help isolate the listener from surrounding sound. The product description also emphasizes extended bass and crisp highs, a sound profile aimed in part at electronic music. That combination makes the Xone appealing if you want a direct, uncomplicated listening setup and do not need Bluetooth or active noise cancellation.
Its in-ear form is also the more promising of these two designs for side sleepers. There is no large ear cup to press between your head and a pillow, although an in-ear headphone can still become uncomfortable if the earpiece pushes into the ear. The package includes small, medium, and large earpieces, which gives you options for finding a seal that feels secure. I would not treat that as a guarantee of overnight comfort; ear shape, sleeping position, and personal tolerance matter.

I would consider the Xone if your priority is a compact wired connection, sound isolation from its acoustic seal, and an emphasis on bass and detailed highs. I would skip it if you want to move around without a cable, listen without a connected device, or use active noise cancellation. Those are not listed features here. It is an adult product, so it is not automatically the answer to a search for a kids headset for side sleepers.
The Sony WH-XB910N takes the opposite approach. It is an over-ear headphone with Bluetooth and active noise cancellation, plus a 3.5 mm headphone jack. Its stated battery life is up to 30 hours. For someone listening during a commute, a long stretch of work, or travel, those features offer more flexibility than the Xone’s wired-only setup. The ear cups also swivel inward for packing into the included case.
Sony’s sound features are aimed at listeners who enjoy pronounced low frequencies. The WH-XB910N enhances bass and offers sound presets for adjusting the listening profile to different preferences or music. That makes it the more adaptable choice if you want to change your sound rather than rely on one fixed presentation. The over-ear design may also appeal to someone who dislikes inserting earpieces into the ear.
The main compromise for side sleepers is the form factor. Ear cups that surround the ears take up more space between your head and the pillow than in-ear earpieces do. That does not make the Sony unsuitable for every person who sleeps on their side, but the specs do not suggest a low-profile sleep design. I would choose it for wireless use, noise cancellation, and longer listening away from a charger, not as my first pick for lying on my side.
• Best fit for a compact in-ear design → Allen & Heath Xone:XD-20. It uses earpieces that sit in the ear rather than ear cups that surround it.
• Best for Bluetooth listening → Sony WH-XB910N. Bluetooth gives it a wireless option that the wired Xone does not list.
• Best for active noise cancellation → Sony WH-XB910N. Its listed noise control includes active noise cancellation; the Xone relies on an acoustic seal for sound isolation.
• Best for side sleepers who want to avoid large ear cups → Allen & Heath Xone:XD-20. Its in-ear shape is the more sensible starting point, though pillow comfort is personal.
• Best for choosing among sound presets → Sony WH-XB910N. It offers presets for tailoring the sound, alongside bass enhancement.
• Best for a wired 3.5 mm connection without relying on Bluetooth → Allen & Heath Xone:XD-20. It is a straightforward wired option. The Sony also has a 3.5 mm jack, so it can be used with a cable as well.
• Best for a folding, case-friendly over-ear setup → Sony WH-XB910N. Its ear cups swivel inward and it includes a carrying case.
A common question is whether an open ear headphones for side sleepers would be more comfortable than either model. Neither of these is an open-ear design: the Xone uses in-ear earpieces, while the Sony uses over-ear cups. If keeping the ears uncovered is important, these two designs may not match that preference.
My Verdict
I would choose the Allen & Heath Xone:XD-20 for side sleepers because its in-ear design avoids the Sony’s larger ear cups, and its acoustic seal suits someone seeking compact listening.
That is a form-factor recommendation, not a promise that any earpiece will stay comfortable against a pillow all night.
I would buy the Sony WH-XB910N instead if wireless listening, active noise cancellation, and up to 30 hours of battery life mattered more to me.
For the specific side-sleeping use case, though, I would start with the Xone.
FAQ
Yes. It supports Bluetooth and also has a 3.5 mm headphone jack. Its stated battery life is up to 30 hours, and it includes active noise cancellation.
The listed feature is sound isolation from an acoustic seal, not active noise cancellation. It also comes with small, medium, and large earpieces, which may help you find a seal that fits your ears.
The choice should come down first to design and features: the Xone is wired and in-ear, while the Sony is wireless-capable, over-ear, and includes active noise cancellation. Check the current price on Amazon before deciding, since it can change.
