If you want flexible wireless and wired listening for a big head, choose Austrian Audio Hi-X25BT; if you need an open-back, wired headphone for home listening, choose GRADO Classic Series SR80. The Austrian Audio is the more adaptable pick, with Bluetooth, USB-C, and a 3.5 mm connection. The GRADO makes a more focused case for an open, spacious presentation at home.
• Austrian Audio Hi-X25BT strength: Bluetooth 5.0, USB-C audio, and 3.5 mm analog listening give you several ways to connect. Trade-off: It has no noise-control feature.
• GRADO Classic Series SR80 strength: Its open-back design is intended to give music a spacious, natural presentation. Trade-off: It is wired, and its open construction is better suited to home listening than situations where you want to keep sound contained.
• Austrian Audio Hi-X25BT suits someone who wants one over-ear headphone for wireless listening and wired use at a desk.
• GRADO Classic Series SR80 suits someone who mainly listens at home and prefers a lightweight, wired open-back design.
The Hi-X25BT is the more flexible all-rounder here. It supports Bluetooth 5.0, analog listening through a 3.5 mm jack, and digital audio over USB-C. That makes it easier to move between a wireless listening session and a wired setup without changing headphones. Its supplied cables are 1.4 m for the jack connection and 1.2 m for USB-C, and a 3.5 mm-to-6.3 mm adapter is included for compatible equipment with that larger jack.
For a larger head, comfort is worth considering alongside connectivity. Austrian Audio specifies soft, slow-retention memory-foam earpads and an over-ear fit. Those details point toward a cushioned design for longer listening sessions, although the sheet does not give a headband adjustment range or a fit measurement, so I would not assume that every big-headed listener will find the fit roomy. At 270 g, it has a stated weight to consider if you are sensitive to heavier headphones. The all-metal hinges are a sturdier design choice, while the closed-back construction makes it the more contained option of these two.
The company describes its sound as clear and precise, and specifies a 44 mm dynamic driver, a frequency range of 18 Hz to 22 kHz, and 25-ohm impedance. It also supports up to 30 hours of Bluetooth playback, and listening by cable remains possible. Bluetooth range is listed as 10 meters. The specification does not list noise control, so this is not the pick for someone who needs a stated noise-canceling feature.

Who should skip it: Skip the Hi-X25BT if open-back listening is your priority, or if you want a headphone with a stated noise-control feature.
GRADO Classic Series SR80: Who It's For
The SR80 is the more specialized choice: a wired, open-back over-ear headphone for home listening. GRADO describes its presentation as lively and immediate, with clear vocals, detailed highs, and a spacious sense of separation between instruments. That combination is aimed at listeners who want music to feel open and engaging rather than choosing a headphone primarily for wireless convenience.
Its open-back design is a meaningful part of the decision. It is intended to let sound feel more natural and spacious, but it also makes the SR80 less suited to places where you want a closed-back style of isolation. For a quiet room, that may be an acceptable trade-off; for shared spaces or listening on the move, the open construction and fixed wired connection are important limitations to weigh.
Who should skip it: Skip the SR80 if you need Bluetooth, USB-C audio, or a closed-back design for listening around other people.
• Best for wireless listening → Austrian Audio Hi-X25BT. Bluetooth 5.0 and up to 30 hours of wireless playback give it a clear practical advantage over the wired-only SR80.
• Best for switching between connection types → Austrian Audio Hi-X25BT. It supports Bluetooth, USB-C audio, and analog 3.5 mm listening, so you can choose a connection to suit your setup.
• Best for an open-back presentation → GRADO Classic Series SR80. Its open construction is designed for a more spacious, natural-feeling sound.
• Best for a desk with a larger headphone jack → Austrian Audio Hi-X25BT. Its included 3.5 mm-to-6.3 mm adapter supports equipment with a 6.3 mm input.
• Best for a lightweight wired home setup → GRADO Classic Series SR80. Its listed strengths include a lightweight design and a wired connection suited to home use.
• Best for a stated long wireless-playback allowance → Austrian Audio Hi-X25BT. The listed maximum is up to 30 hours over Bluetooth; the SR80 has no battery because it is wired.
• Best for big-head shoppers weighing comfort details → Austrian Audio Hi-X25BT for its memory-foam earpads, or GRADO SR80 for its lightweight design. Neither data sheet gives headband dimensions, so fit cannot be settled from the specs alone.
• Best for someone seeking “with mic” open-ear headphones for a big head → neither based on the listed features. The SR80 is open-back, but neither product sheet specifies a microphone, and the SR80 is not described as an open-ear design.
In my opinion, I would choose the Austrian Audio Hi-X25BT for a big head if I wanted the more versatile everyday headphone: it offers wireless, USB-C, and analog connections, plus memory-foam earpads and up to 30 hours of Bluetooth playback. Its fit still cannot be guaranteed from the listed specs alone.
I would pick the GRADO SR80 instead for focused home listening when an open-back presentation matters more than wireless convenience. I would not call either one the best gaming headphones for a big head based on these specifications: neither sheet lists a microphone, and neither provides a fit measurement.
First, decide where you will listen most. The Hi-X25BT’s closed-back design and multiple connection options make it the more adaptable choice for moving between a desk and wireless listening. The SR80’s open-back design is specifically oriented toward home listening, where its spacious presentation is easier to appreciate. Neither sheet lists noise control, so do not treat either as a noise-canceling option.
Next, separate comfort clues from fit guarantees. Austrian Audio lists slow-retention memory-foam earpads and a 270 g weight. GRADO emphasizes its lightweight build, comfortable headband, and flexible cable. These are useful design details, but neither product sheet supplies headband measurements or a stated range of adjustment. If you have struggled to find headphones that fit a larger head, those missing measurements matter more than a broad comfort description.
Finally, check the connection you actually need. The Hi-X25BT is the straightforward fit if you want Bluetooth or USB-C as well as a standard 3.5 mm jack. The SR80 is the simpler wired option, with a 3.5 mm mini jack and a 1/4-inch adapter. If price is part of your decision, check the current price on Amazon using the page’s button; I can’t make a price comparison from the product details here.
Yes. It supports Bluetooth 5.0 and lists up to 30 hours of wireless playback. It can also be used through its 3.5 mm analog connection or USB-C audio connection.
It is designed with home listening in mind and uses an open-back construction intended to create a spacious, natural presentation. That does not make it the right fit for every home: its wired connection and open design are less convenient if you want wireless use or a more contained listening experience.
Which headphone is more suitable for a big head?
Neither product sheet lists a microphone, so I would not choose either on the assumption that it includes one. The Hi-X25BT offers Bluetooth and wired connections; the SR80 is wired and open-back, but those details alone do not establish gaming-chat support.
