If you want in-ear monitors with a choice of eartips and a cable that hooks over the ear, choose BASN Bmaster Triple Drivers; if you need lightweight open-back headphones for spacious, private-room listening, choose Audio-Technica ATH-R50X. For a big head, the key distinction is fit style: BASN avoids a headband, while Audio-Technica’s fit depends on one.
Neither is a true wireless option, and neither is an obvious match for every setting. BASN isolates sound with in-ear earpieces; Audio-Technica’s open-back design lets sound pass through. That difference matters more than the driver count when deciding which one fits your daily routine.
BASN Bmaster Triple Drivers vs Audio-Technica ATH-R50X at a Glance
• Audio-Technica ATH-R50X: Open-back, over-ear design with a lightweight 207 g build and two detachable cables; the trade-off is that open-back headphones do not isolate outside noise.
• BASN suits listeners who want a secure-feeling in-ear option for music, monitoring, or settings where keeping outside sound down matters.
• Audio-Technica suits listeners who want open, spacious listening in a private room and prefer an over-ear headphone.
• For a big head: BASN sidesteps headband fit; Audio-Technica may appeal if you prefer over-ear comfort, but the supplied details don’t specify headband adjustment range.
The BASN Bmaster is a wired in-ear monitor with two dynamic drivers and one balanced armature. Its stated frequency range is 20 Hz–20 kHz, and the sound is described as having substantial low frequencies, clear midrange, and treble detail. Those figures and design cues point to a compact listening option for someone who wants an in-ear monitor rather than a full-size headphone.

Its fit is shaped by the supplied eartips: three sizes of memory foam and six silicone eartips in small, medium, and large. The cable’s earhooks are intended to help the earpieces stay in place, and the MMCX connections rotate and allow cable replacement. For musicians or anyone who moves around while listening, that combination may be more appealing than a conventional straight cable. The included inline-microphone cable also makes it relevant to shoppers looking for in ear earbuds for big head without a headband. They are wired, however, so they are not with microphone true wireless earbuds for big head.
I’d skip the BASN if you want a roomy, open-back presentation or dislike putting earpieces into your ears. Its isolation is a benefit for focused listening, but it also means it is not designed to leave your ears open to surrounding sound. The fit is personal: the range of tips gives you options, but it cannot guarantee that every ear will find a comfortable seal.
The ATH-R50X is an over-ear, fully open-back wired headphone intended for production work such as mixing and mastering, as well as listening in a private space. Its open construction is designed to allow airflow and avoid internal resonance, while its stated soundstage is wide and realistic. In practical terms, this is the pick for someone who values an open presentation and does not need to block out the room.
At 207 g, it is described as lightweight, with a headband designed for extended comfort and replaceable velour earpads. It comes with two detachable cables: one 3.0 m and one 1.2 m, both connecting at the left earcup with a 2.5 mm twist-lock connector. A 6.3 mm adapter and carrying pouch are also included. That cable choice can suit a stationary desk setup or a shorter connection, though this remains a wired headphone rather than a wireless everyday headset.
Side-by-Side: Which Should You Choose?
• Best for avoiding headband fit concerns → BASN Bmaster Triple Drivers. Its in-ear design does not rely on a band across a big head.
• Best for a wide, open listening presentation → Audio-Technica ATH-R50X. Its fully open-back construction is designed for a spacious soundstage.
• Best for sound isolation → BASN Bmaster Triple Drivers. Its in-ear monitor design is described as helping keep outside noise from interfering.
• Best for a private studio or desk setup → Audio-Technica ATH-R50X. It is intended for production listening, with 3.0 m and 1.2 m cable options.
• Best for choosing between tip materials and sizes → BASN Bmaster Triple Drivers. It includes memory foam and silicone eartips in several sizes.
• Best for replaceable headphone cables → Audio-Technica ATH-R50X. Both supplied cables detach from the earcup; BASN also has detachable MMCX cables, but the connection system differs.
• Best for an inline microphone cable → BASN Bmaster Triple Drivers. An adjustable inline-mic cable is included; the ATH-R50X sheet does not specify a microphone.
• Best for listening while staying aware of the room → Audio-Technica ATH-R50X. Its open-back design does not aim to isolate outside sound, unlike BASN’s isolation-focused fit.
I’d choose the BASN Bmaster Triple Drivers for a big head if the main concern is avoiding a tight or uncertain headband fit, and I’d value its selection of eartips and earhook cable. That recommendation is about fit style, not a guarantee of comfort: in-ear earpieces still need to suit your ears.
