If you want a secure, sound-isolating wired in-ear monitor for a big head, choose BASN Bmaster; if you need an adjustable USB-C classroom headset for a big head, choose XOSDA USB C Classroom. The key difference is how they fit: BASN sits in your ears with over-ear cables, while XOSDA rests on them with an adjustable headband.
BASN Bmaster vs XOSDA USB C Classroom at a Glance
• BASN Bmaster’s biggest strength: hybrid triple-driver in-ear design, memory-wire fit, and included tips in several styles and sizes. Trade-off: wired 3.5 mm connection, not USB-C.
• XOSDA USB C Classroom’s biggest strength: adjustable on-ear headband and direct USB-C connection for compatible devices. Trade-off: it has no microphone and does not provide BASN’s in-ear seal or detachable MMCX cables.
• For music detail and a fitted in-ear style: BASN is the closer match.
• For school listening with a USB-C device: XOSDA is the more straightforward choice.
• For a larger head: XOSDA’s adjustable headband is the clearer fit option; BASN instead offers memory wire and a choice of ear-tip styles and sizes.
BASN Bmaster is a wired in-ear monitor built around a hybrid driver system: one balanced-armature driver and two dynamic drivers, including a 10 mm dynamic driver. The product information describes the dynamic driver as handling bass while the balanced-armature driver covers mid and high frequencies. That arrangement is aimed at listeners who want a more involved, detailed personal-listening setup rather than a simple classroom headset.
How We Research
We compare products from their published specs and features; the verdicts below are our independent editorial opinions.
Its over-the-ear memory wire is shaped to help the earpieces stay put, and the included assortment of 12 pairs of tips spans silicone and memory foam in multiple sizes and styles. For someone looking for an extra bass kids headset for big head, though, this is not a headband headset at all: it is an adult-oriented in-ear monitor, and the “fit” comes from choosing tips and shaping the ear hooks. That may suit a listener who likes an ear-canal seal, but it is not the obvious pick for someone who needs adjustable space around a larger head.
BASN makes more sense for a musician, audio worker, or everyday listener who wants in-ear isolation and wired audio through a 3.5 mm jack. Its listed noise isolation is up to 37 dB, and it includes two detachable MMCX cables, one with a microphone and controls. Skip it if your device needs a USB-C plug and you do not have a compatible adapter, or if you would rather have padded on-ear cups than eartips inside your ears.
XOSDA is an on-ear wired headset designed for classroom use with USB-C devices. Its adjustable headband is intended to fit a range of head sizes, and the soft foam ear cushions offer a different kind of contact from BASN’s in-ear tips. For someone searching for wireless headphones for big head, it is important to know that this model is not wireless: it connects by cable, and its headband adjusts rather than relying on a wireless connection or a battery.
The direct USB-C plug is the practical centerpiece. XOSDA says the headphones work with USB-C audio devices, including school Chromebooks, tablets, phones, and laptops. That makes it a sensible option when students need to plug into compatible equipment without using a 3.5 mm headphone jack. The listing also describes a lightweight, swivel design and a one-year warranty.
Side-by-Side: Which Should You Choose?
• Best for a USB-C-only school device → XOSDA USB C Classroom. It connects through USB-C, provided the device supports USB-C audio.
• Best for a wired in-ear monitor setup → BASN Bmaster. Its hybrid drivers, over-ear memory wire, and in-ear tips suit that use better.
• Best fit option for a larger head → XOSDA. Its adjustable headband is made to accommodate a range of head sizes, including children and adults.
• Best for tailoring the fit inside your ears → BASN. It includes 12 pairs of tips in different sizes and styles, plus memory wire that can be shaped around the ears.
• Best for a stated noise-isolation figure → BASN. The listed isolation is up to 37 dB; XOSDA’s description mentions some isolation from its cushions but gives no comparable figure.
• Best for calls and cable controls → BASN. One included cable has a microphone and controls for calls, volume, and playback. XOSDA has no microphone.
• Best for a conventional on-ear classroom headset → XOSDA. Its foam cushions and adjustable band are closer to the familiar school-headphone format.
• Best for replaceable cable customization → BASN. Its MMCX cables detach, allowing compatible cables to be used.
My Verdict
I’d choose BASN instead for personal music listening, a snug in-ear fit, and the included microphone cable. My recommendation is XOSDA for the stated big-head classroom use, with the important caveat that it is wired and has no microphone.
XOSDA is the more direct fit choice because it has an adjustable headband designed for a range of head sizes. BASN uses in-ear tips and over-ear memory wire, so headband size is not the relevant fit measure.
No. The product details specify that it does not have a microphone. BASN includes a separate cable with a microphone and controls for calls and playback.
BASN uses a wired 3.5 mm connection, while XOSDA connects by USB-C. Check whether your device supports 3.5 mm audio or whether you have a compatible adapter before choosing BASN.
Choose XOSDA if the device has a USB-C audio connection and you want an adjustable on-ear headset. BASN may suit personal in-ear listening, but it uses a 3.5 mm jack and a different fit style.
