If you want a simple wired headset with a microphone and clear, bass-forward specs for flights, choose Sony MDRXB450AP; if you need over-ear wireless listening with rechargeable power and stated noise-cancelling features, choose SXFJF Headphones Deep Heavy.
The Sony’s appeal is straightforward: plug in, listen, and use the inline microphone and controls. The SXFJF offers more travel-focused conveniences on paper, including Bluetooth, folding earcups, and an over-ear fit. Neither is a universal pick; the main decision is whether you prefer wired simplicity or wireless features.
• Sony MDRXB450AP — biggest strength: Wired on-ear design with an inline microphone, volume control, and a 30 mm driver; trade-off: it needs a cable and has no listed noise control.
• SXFJF Headphones Deep Heavy — biggest strength: Bluetooth, rechargeable power, foldable over-ear construction, and stated active noise cancelling; trade-off: the provided specifications do not state battery runtime.
• Sony is for listeners who want a direct wired connection, a built-in call mic, and bass-forward sound features.
• SXFJF is for travelers who prefer wireless over-ear headphones and want noise-cancelling features described in the product information.
The Sony MDRXB450AP is a wired, on-ear headset built around bass-forward listening. Its 30 mm drivers have a listed frequency range of 5–22 kHz, and the inline remote includes a microphone and volume control. It connects through a 3.5 mm jack, so its basic setup does not depend on Bluetooth or rechargeable headphone power.
That makes it a sensible option if you want to listen from a compatible device with a cable and take hands-free calls through the inline mic. The listed 1.2 m cord has a tangle-resistant design, and the earcups swivel for portability. Sony also lists compatibility with Apple and Android smartphones, plus a SmartKey app for customizing the inline remote function.

SXFJF Headphones Deep Heavy: Who It's For
The SXFJF Headphones Deep Heavy takes a more travel-oriented feature approach. It is an over-ear Bluetooth headset with foldable construction, rechargeable power, and a microphone. Its product information also describes active noise cancelling and closed-back earcups with isolation pads. Those features make it the more obvious fit if you want to avoid a wired connection and prefer earcups that sit around your ears.
It is worth considering for flights if you want Bluetooth listening and a foldable design for packing. The listing also describes easy controls and hands-free calls, so it covers more than music playback. Its stated frequency response is 20–20,000 Hz, and the listed weight is 240 g. Those details provide a useful point of comparison, though they do not establish how it will sound or feel for every listener.
The key limitation is missing battery-runtime information. The headset is described as rechargeable, but the available specifications do not say how many hours a charge lasts. Its noise-cancelling feature is stated, but no performance figures are provided. If you need a precisely documented runtime or a wired-first setup, the Sony’s more specific connection details may be easier to judge.
• Best for a wired connection → Sony MDRXB450AP. It uses a 3.5 mm jack and a 1.2 m cord, while the SXFJF is presented primarily as a Bluetooth headset.
• Best for wireless listening → SXFJF Headphones Deep Heavy. Bluetooth is central to its design; the Sony’s listed connectivity is wired.
• Best for an inline microphone and volume control → Sony MDRXB450AP. Those controls are specified on the cable, alongside compatibility with Apple and Android smartphones.
• Best for over-ear coverage → SXFJF Headphones Deep Heavy. Its ear placement is over-ear; the Sony sits on the ears.
• Best for stated noise-cancelling features → SXFJF Headphones Deep Heavy. The product information describes active noise cancelling and sound-isolation pads. Sony lists no noise control.
• Best for folding into a compact form → SXFJF Headphones Deep Heavy. Foldability is listed as a feature; the Sony’s specified portability detail is its swivel design.
• Best when you want to avoid charging the headphones → Sony MDRXB450AP. Its wired connection does not require headphone battery power, while the SXFJF is rechargeable.
• Best for a bass-forward wired headset → Sony MDRXB450AP. It lists an Acoustic Bass Booster and 30 mm drivers; the SXFJF also emphasizes deep bass, but pairs that with Bluetooth and over-ear construction.
The phrase memory foam ear cushions headband headphones for flights also does not match a confirmed feature here: neither data set specifies memory foam. The SXFJF does describe soft earcups and an over-ear fit, while the Sony is on-ear. I would not treat either as a memory-foam model based on the available details.
My Verdict
I would choose the SXFJF Headphones Deep Heavy for flights if wireless listening, over-ear coverage, folding construction, and stated active noise cancelling are my priorities. Those features line up more closely with a traveler’s wish list, although its battery runtime is not specified.
I would pick the Sony instead if I wanted a wired headset with an inline microphone and volume control, and did not need noise control. My recommendation is SXFJF for the flight-focused use case, with the runtime information gap kept firmly in mind.
The SXFJF is the more travel-feature-focused option: it is over-ear, foldable, Bluetooth-enabled, rechargeable, and described as having active noise cancelling. The Sony is wired and on-ear, with no listed noise control.
Yes. The Sony has an inline microphone for hands-free calls, along with volume control. It connects by wire through a 3.5 mm jack.
Yes. Its specifications describe Bluetooth connectivity and a microphone for hands-free calls. The available details do not specify how long its rechargeable battery lasts.
Only the SXFJF is described as having active noise cancelling and sound-isolation pads. Sony lists no noise-control feature. The provided information does not give comparative noise-reduction measurements, so it cannot establish how much noise either headset blocks in a particular cabin.
