For headphones target wired shopping for teachers, my pick is the XOSDA 2: its rotating noise-reducing mic and 3.5 mm plug suit calls and classroom devices.
Bose is the runner-up if you want active noise cancellation and up to 30 hours of wireless listening instead.
• FiiO K9Pro — best for a dedicated desk audio setup; pick this if you need a headphone amplifier with multiple wired outputs and support for demanding headphones.
• Frienda 48 — best for equipping a classroom; pick this if you need a large set of adjustable, lightweight wired headphones with 3.5 mm plugs.
• XOSDA 2 — best for teacher calls and online lessons; pick this if a rotating noise-reducing microphone and simple 3.5 mm connection matter.
• XOSDA Headsets — best for a small office or school team; pick this if you need several wired headsets with adjustable boom mics.
• Bose Gen QuietComfort — best for focused personal listening; pick this if you prefer wireless active noise cancellation and long stated battery life.
The FiiO K9Pro is not a conventional pair of headphones. It is a desktop DAC and headphone amplifier: you connect your headphones to it, then connect it to a computer, phone, player, or home audio system. I put it first for shoppers who want a desk-based audio hub and value a wide choice of connections over a headset they can wear straight out of the box.
Its front panel offers 4-pin XLR, 4.4 mm balanced, and 6.35 mm single-ended headphone outputs. That range can make it easier to pair the unit with different compatible headphones without treating the computer’s own audio connection as the whole setup. The manufacturer lists a recommended headphone impedance range of 16–600 ohms, so it is aimed at models that may need more drive than basic earbuds or classroom headsets.
There is also a substantial set of inputs and outputs for a stationary system, including USB, coaxial, optical, RCA, and balanced XLR connections. Bluetooth 5.1 supports several codecs, including LDAC and aptX Adaptive. That is useful if you want to bring wireless playback into a desktop setup, but it does not make the K9Pro itself a pair of wireless headphones.
For teachers, this is a specialized choice rather than the practical answer for a classroom call. There is no headset microphone listed, and the desktop form is built around a home or desk setup. I recommend it if your priority is connecting capable headphones and other audio equipment; I would choose one of the XOSDA headsets for straightforward online lessons.
How We Research
We compare products from their published specs and features; the verdicts below are our independent editorial opinions.

The practical appeal is simplicity. A standard 3.5 mm plug can connect to compatible phones, computers, and other equipment with that jack. The lightweight construction and soft ear pads are intended to make the headsets manageable for students to wear, while adjustment helps accommodate different users. The listed frequency range is 20 Hz to 20,000 Hz, a broad specification that describes the range of audio frequencies the headphones are designed to reproduce.
There is an important limitation for virtual teaching: the provided details do not list a built-in microphone. These are headphones for listening, not a clear all-in-one option for speaking during online lessons or calls. The listing also specifies no noise-control feature, so they are not the pick for blocking a busy room.
I would consider Frienda when the goal is providing a listening headset at many desks, especially for school activities that do not require every student to speak. The trade-off is that a teacher needing to lead meetings through the headset will need a separate microphone or a different product. That makes this bulk set less versatile for live instruction than the XOSDA options.
The XOSDA 2 is a two-headset wired set with a rotating boom microphone. For teachers who spend time on video calls, virtual lessons, or online seminars, that combination is more directly useful than headphones made only for listening. The microphone can be moved out of the way when it is not needed, and the 3.5 mm plug keeps the connection straightforward on compatible devices.
Its microphone is described as noise-reducing, which is intended to help manage background sound on calls. The boom can be positioned to suit the wearer, and the adjustable headband and ear cushions address fit and routine shared use. The published specifications also list sound isolation, media controls, a 32-ohm impedance, and a 20 Hz–20,000 Hz frequency range. These details describe a conventional wired headset rather than a wireless system.
For a teacher, that means fewer connection steps than a Bluetooth headset and a dedicated mic for talking through lessons. It may also suit a home office or a student who needs a headset for computer-based schoolwork. Compatibility still depends on the device having the right 3.5 mm connection; some computers or tablets may need an adapter, which is not included in the listed details.
The main trade-off is the small bundle size: two headsets are aimed at a pair of users, not outfitting a whole class. I rank it ahead of the five-pack because the two-piece set’s microphone features are clearly suited to teacher communication. If several colleagues or students need headsets, the larger XOSDA bundle may be a more practical match.
XOSDA Headsets
The product details list sound isolation, media controls, a 32-ohm impedance, and a 20 Hz–20,000 Hz frequency range. The boom’s rotating design lets the user move it when it is not needed, and the adjustable fit makes the headsets easier to assign across different users. For a teacher coordinating a small team or keeping spare call headsets available, having several wired units together can be more useful than buying a personal wireless model.
The big limitation is that the available information does not specify compatibility with every jack arrangement. A 3.5 mm plug works with devices that support it, but laptop or tablet ports vary, so check the device connection before choosing. These are also not described as Bluetooth headphones; their strength is a simple wired setup, not freedom to move away from the device.
I would choose this pack over Frienda’s classroom headphones when group members need microphones for calls or online instruction. It is not as tailored to a single teacher as the two-pack, and the information does not identify special classroom features beyond the headset design and bundle. For people comparing multipoint headphones for teachers, note that these wired headsets do not offer multipoint Bluetooth pairing; their appeal is avoiding wireless pairing altogether.
Bose’s second-generation QuietComfort Ultra is the wireless alternative in this guide. It is an over-ear Bluetooth headset with active noise cancellation, built-in microphones, and a stated battery life of up to 30 hours. It is designed for someone who wants personal listening without a cable attached during use, not for equipping a classroom.
For a teacher working between planning time and calls, wireless listening may feel more convenient than staying tethered to a computer. Bose lists noise-rejecting microphones with background-noise suppression for calls, along with spatial audio features for music and video. The package information also lists a USB cable and a 3.5 mm cable, but the headset’s primary connectivity is Bluetooth.
The key trade-off is that this is a personal, feature-rich headset rather than a bulk set of classroom gear. It is not a wired-first choice, and the provided details do not list multipoint connection support. Shoppers searching for multipoint headphones for teachers should not assume this feature is included based only on Bluetooth connectivity.
