If you want the best-sounding wireless earbuds for your own music, movies and calls, choose Bowers & Wilkins Pi8; if you need a bulk set of 100 wired USB-C headphones for a classroom of students, choose XOSDA USB C Classroom. These two products are not really rivals — they are built for completely different buyers — but that is exactly why this comparison matters. One is a premium personal audio device, the other is a school-supply workhorse.
• Bowers & Wilkins Pi8 — biggest strength: a true 24-bit wireless connection with 12 mm carbon drivers, six microphones and active noise cancellation, aimed at high-fidelity listening.
• Bowers & Wilkins Pi8 — biggest trade-off: it is a personal, one-person product with a short per-charge battery figure, so it is not something you hand out to a room of kids.
• XOSDA USB C Classroom — biggest strength: a 100-pack of USB-C wired on-ear headphones that plug straight into Chromebooks, tablets and laptops, individually wrapped and ready to distribute.
• XOSDA USB C Classroom — biggest trade-off: wired only, no microphone, no noise cancelling, and an on-ear plastic build rather than a premium listening experience.
• Who Bowers & Wilkins Pi8 is for: one person who wants serious sound quality and wireless freedom.
• Who XOSDA USB C Classroom is for: teachers, schools and IT buyers who need to equip many students at once.
The Pi8 is a true wireless in-ear earbud designed around sound quality first. Its headline feature is a true 24-bit wireless connection backed by the latest Qualcomm chipset and aptX Lossless, which is about getting as close to the original recording as wireless audio reasonably can. Each earbud uses a 12 mm carbon cone driver derived from the company's over-ear headphone technology, and the claimed result is lower distortion and finer high-frequency detail. You also get active noise cancellation, six built-in microphones for calls, and Bluetooth 5.4 with a stated range of around 10 metres.
Who should buy it? Someone who listens critically, takes a lot of calls, travels, and wants one pair of earbuds to do the heavy lifting. The 10 Hz–20 kHz-plus frequency response, 8-ohm impedance and 103 dB sensitivity figures point to a driver built for detail rather than brute volume. Who should skip it? Anyone shopping for a school, a computer lab or a family of kids. This is a single-user premium product, not a bulk item — and the stated battery figures (up to 6.5 hours of listening, with a 15-minute charge giving around 2 hours) reflect a compact personal device, not something built to survive a whole school day in a backpack.
XOSDA USB C Classroom: Who It's For
The XOSDA USB C Classroom set is the opposite kind of product, and that is its whole point. You get 100 wired USB-C on-ear headphones in mixed colours, individually wrapped, in a single bulk purchase. The model is LS857C, made of TPE and plastic, with an adjustable headband, soft foam ear cushions and a tangle-free cord. The impedance is 32 ohm and the plug is USB-C — the modern connector that newer Chromebooks, iPads, tablets and most laptops now use.
Comfort and durability are the design priorities. The headband adjusts to fit a wide range of head sizes, from kids to adults, and the lightweight swivel build is meant to cope with daily handling by children. XOSDA states the materials and connectors are reinforced, and the set comes with a one-year manufacturer warranty. There is no microphone and no active noise cancellation; the soft cushions provide some passive sound isolation, and that is it. Media controls sit on the cable.
Who should buy it? Teachers, schools, districts and IT coordinators who need a class set of headphones that just work when plugged in. The 100-pack format means every student gets their own pair without sharing, which is a real practical advantage in a classroom. Who should skip it? Anyone who wants wireless freedom, noise cancelling, a microphone for calls, or high-fidelity sound. The 32-ohm wired design and plastic on-ear build are honest and functional, but they are not aimed at a critical listener.
Side-by-Side: Which Should You Choose?
• Best for noise cancelling → Bowers & Wilkins Pi8. It has active noise cancellation; the XOSDA set has none.
• Best for calls → Bowers & Wilkins Pi8. Six built-in microphones versus no microphone at all on the XOSDA.
• Best for a classroom or school → XOSDA USB C Classroom. A 100-pack of USB-C plug-and-play headphones is exactly what a class set needs.
• Best for USB-C devices in bulk → XOSDA USB C Classroom. Built for newer Chromebooks, iPads, tablets and laptops, one pair per student.
• Best for wireless freedom → Bowers & Wilkins Pi8. Bluetooth 5.4 with roughly 10 metres of range; the XOSDA is wired.
• Best for durability around kids → XOSDA USB C Classroom. Adjustable headband, swivel design and a stated one-year manufacturer warranty.
• Best for one person who wants everything in one pair → Bowers & Wilkins Pi8. Retransmission case, wireless charging case, touch controls and an app.
In my opinion, the choice here is not close — it is simply a matter of who you are. If you are buying for yourself and you care about how music and movies actually sound, I would buy the Bowers & Wilkins Pi8: the carbon drivers, 24-bit connection, ANC, six microphones and the retransmission charging case make it the far more capable personal product. If you are equipping a classroom, I would buy the XOSDA USB C Classroom set, because 100 wired USB-C headphones in mixed colours, individually wrapped with a one-year warranty, solve a problem the Pi8 was never designed for. Decide which job you are actually doing, then pick.
Yes. The Pi8 is a true wireless earbud using Bluetooth 5.4 with around 10 metres of range. The XOSDA classroom set is wired with a USB-C plug and no Bluetooth.

The XOSDA USB C Classroom set. It is sold as a 100-pack in mixed colours, individually wrapped, and plugs directly into newer Chromebooks, iPads, tablets and laptops — no pairing, no charging.
