If you want wired in-ear headphones with an acoustic seal for flights, choose Allen & Heath Xone:XD-20; if you need foldable over-ear headphones with 40 mm drivers, choose Sony MDRX05/BS. For air travel, I’d lean toward the Sony’s over-ear design for its cushioned earpads, while the Allen & Heath offers a more compact in-ear alternative.
Allen & Heath Xone:XD-20 vs Sony MDRX05/BS at a Glance
• Sony MDRX05/BS: 40 mm drivers, seamless earpads, and a dual-folding design; its main trade-off is a larger over-ear form than an in-ear pair.
• Choose Allen & Heath if you want a small wired pair with sound isolation and three earpiece sizes to choose from.
• Choose Sony if you prefer padded over-ear headphones and want a design that folds for storage.
• Both are wired and use a 3.5 mm jack, so neither is a cable-free option.
The Xone:XD-20 is a wired in-ear headphone with a 13.6 mm driver and a stated frequency range of 20 Hz to 20 kHz. Its acoustic seal is intended to provide sound isolation, while its sound profile is described as suited to electronic music, with extended bass and crisp highs. That combination makes it a reasonable fit for someone who wants an in-ear design for music listening and values a seal around the ear canal.
The package includes small, medium, and large earpieces. That gives buyers options for finding a more secure, comfortable fit, which matters when wearing in-ear headphones for a stretch of travel. The listed item weight is 13.61 g, a comparatively light figure for the headphones themselves. For someone packing light or preferring not to wear an over-ear headband, that compact in-ear format may be appealing.
The trade-off is straightforward: this is a wired in-ear model, not a folding over-ear pair. There is no listed wireless connection or folding mechanism, and a good seal depends on choosing earpieces that fit. Its sound isolation is not described as active noise cancellation, so buyers should not expect that feature. Skip it if you want cushioned over-ear earpads or a folding design for packing.

Sony’s MDRX05/BS is an over-ear headphone with 40 mm dynamic drivers and a stated frequency range of 4 Hz to 24 kHz. The product information emphasizes bass response, including an Advanced Direct Vibe structure. That makes it a natural option for listeners who want a bass-forward presentation and prefer larger earcups over in-ear tips.
For travel, the dual-folding design is a practical point in its favor: the headphones can fold for more compact storage than a fixed over-ear design. Sony also specifies seamless earpads for long-term comfort. Those details may suit someone settling in for a flight with headphones worn over the ears rather than inserted into them. The cable has Apple controls, and the connection is wired through a 3.5 mm jack.
There is an important distinction in the connection details: the listing identifies the headphones as wired, but also includes Bluetooth in its connectivity information. It does not provide enough detail to establish how that wireless feature works or what it requires, so I would not treat Bluetooth as a guaranteed cable-free listening setup without checking the product details. The listed item weight is 16 ounces, making this a substantially more substantial item than the Xone:XD-20’s listed 13.61 g. Skip it if your priority is a very light in-ear pair rather than over-ear headphones.
• Best for an in-ear fit with sound isolation → Allen & Heath Xone:XD-20. Its acoustic seal and included S/M/L earpieces make fit the central part of its design.
• Best for larger drivers → Sony MDRX05/BS. Its 40 mm dynamic drivers are much larger than the Xone’s 13.6 mm driver, though driver size alone does not establish which one will sound better to you.
• Best for a folding design → Sony MDRX05/BS. The dual-folding structure is specifically useful when you want headphones that can fold down for storage.
• Best for a lightweight listed item weight → Allen & Heath Xone:XD-20. Its listed weight is 13.61 g, compared with 16 ounces for the Sony.
• Best for choosing among included earpiece sizes → Allen & Heath Xone:XD-20. It comes with small, medium, and large earpieces; the Sony instead uses over-ear earpads.
• Best for a bass-focused over-ear format → Sony MDRX05/BS. Sony specifies 40 mm drivers and a structure designed to emphasize bass response.
• Best for a wired 3.5 mm connection → Both. Each product lists a 3.5 mm jack, so the basic wired connection is not a deciding difference.
• Best for flights if you want a compact in-ear alternative → Allen & Heath Xone:XD-20; if you prefer padded over-ear headphones that fold, Sony MDRX05/BS. Your preferred fit matters more here than a claim that one design will suit every traveler.
Buying Considerations Before You Choose
For flights, start with the physical style you actually want to wear. The Xone:XD-20 sits in the ear and includes three earpiece sizes, so comfort and isolation depend partly on getting a suitable seal. The Sony’s seamless earpads sit over the ears, and its folding design may be useful when putting headphones away. Neither product’s information gives a battery life, so these should not be treated as rechargeable headphones. In particular, the Xone is specified as wired; it is not a rechargeable neckband headphone.
The phrase “best volume limiting open ear headphones for flights” points to two features neither sheet lists: volume limiting and an open-ear design. The Xone is an in-ear model with a seal, while the Sony is an over-ear model. Likewise, someone searching for the “best clip on earbuds for flights” is looking for a fit style that is not specified for either product. These labels should not be used as substitutes for the actual designs.
Finally, both products are wired and list a 3.5 mm jack. The Sony’s connectivity details also mention Bluetooth, but they do not clarify how that feature operates. If wireless listening is essential, verify the exact connection arrangement before deciding.

For flights, I would choose the Sony MDRX05/BS if I wanted over-ear padding and a folding design for storage. Its 40 mm drivers and bass-focused construction also suit someone who prefers that style of presentation.
I would choose the Allen & Heath Xone:XD-20 instead if a lightweight in-ear fit and included earpiece options matter more. My flight pick is the Sony, but only for a traveler who prefers over-ear headphones and is comfortable with the connection details.
