The earcups of headphones can be either open-back or closed-back. In closed-back headphones, the sound from the drivers is contained within the earcups, whereas in open-back designs the sound can move more freely in and out of the headphones.

To prevent sound bleeding into a microphone, a closed-back model is usually the better choice. This makes them particularly suitable for recording situations and for use in classroom environments where multiple students are working simultaneously.

Closed-back headphones may create a stronger perception of low frequencies due to their enclosed design. However, this does not necessarily mean that they exaggerate bass. Well-designed headphones intended for studio or critical listening can still offer a relatively flat and neutral frequency response.

Open-back headphones often provide a more natural and open listening experience, which some users may prefer when analysing sound or music. However, they allow more sound to leak in and out, making them less suitable in situations where isolation is required.

When a neutral sound is important, it is therefore more effective to choose headphones designed for critical listening rather than relying solely on whether they are open-back or closed-back.

Using headphones for entertainment purposes (e.g. gaming or listening to music) requires different sound characteristics than for professional, critical listening applications, such as in a studio context when mixing music.

For entertainment purposes, strong bass and a bright sound are often preferred. Therefore, some headphones emphasise the lower and higher frequencies of the spectrum (a so-called V-shaped response). Such headphones might be a good fit if you want your students to experience DJing and producing electronic dance music (EDM).

However, critical listening in music education typically requires more neutral sound characteristics, similar to those used in a studio context, so that students can better analyse the intended sound features. This calls for headphones with a so-called flat frequency response.

Headphones differ in the range of frequencies they are able to reproduce. This is typically expressed in hertz (Hz), for example 20 Hz to 20 kHz, which corresponds roughly to the range of human hearing.

While many headphones claim a wide frequency range, this does not necessarily guarantee accurate sound reproduction across that range. In practice, the consistency of the frequency response is more important than the stated limits.

For most music education applications, it is advisable to choose headphones that cover the full audible spectrum (approximately 20 Hz to 20 kHz) and are designed for balanced or neutral reproduction. This helps students to develop an accurate perception of musical elements.

You probably do not want your students to develop hearing loss. Limiting the listening volume of headphones is therefore important. Keeping volume levels (SPL = sound pressure level) below 85 dB is generally considered safe.

While some headphones include a built-in volume limiter that automatically prevents the volume from becoming too loud, it may be preferable to use headphones in combination with an external limiter (software or hardware), or to choose headphones with a lower maximum output level. If it is not possible to find such a combination within your budget while meeting other important requirements, it is advisable to inform students about the risks of listening at high volume levels and to teach them how to adjust the volume responsibly. However, be aware that providing this information alone will not prevent students from turning up the volume.

Another reason for monitoring headphone volume relates to sound distortion, which can occur when headphone drivers are pushed too hard. Headphones should have sufficient headroom to handle the output levels of the devices they are connected to. In practice, this means choosing headphones with enough maximum output to avoid distortion at 85 dB (SPL).

Not all headphones work equally well with every device. One important factor to consider is impedance, measured in ohms (Ω).

Headphones with a low impedance (typically around 32 ohms) require less power to reach sufficient volume levels. These are generally the best choice for use with devices such as laptops, tablets, and most audio interfaces commonly found in educational settings.

Headphones with a higher impedance (for example 80 ohms or more) are often designed for professional studio use. While they can offer high sound quality, they require more powerful amplification. When connected directly to standard classroom devices, they may produce insufficient volume or lack clarity.

In most music education contexts, choosing low-impedance headphones ensures compatibility, reduces the need for additional equipment, and provides a more consistent user experience.

In addition to impedance, headphones differ in sensitivity, which indicates how efficiently they convert an audio signal into sound.

Headphones with higher sensitivity will produce more volume at the same output level compared to less efficient models. This can be beneficial when working with devices that have limited output power.

Choosing headphones with appropriate sensitivity helps to ensure that students can work at safe listening levels without needing to increase the volume excessively. It also contributes to maintaining sufficient headroom and avoiding distortion.

Headphones reduce external noise in different ways. It is useful to distinguish between passive noise isolation and active noise cancelling.

Passive noise isolation is achieved through the physical design of the headphones, particularly in closed-back models that cover the ears and reduce ambient sound. This is often sufficient in classroom environments.

Active noise cancelling (ANC) uses electronic processing to reduce background noise. While effective in certain situations, it introduces additional complexity, requires power (usually via batteries), and increases cost.

In most music education settings, closed-back headphones with good passive isolation provide a reliable and practical solution without the need for active noise cancelling.

The earcups should be robust enough to withstand frequent use. Pay attention to how they are attached to the headband. Swivel mechanisms and hinges are common failure points, especially in lower-cost models.

If possible, choose headphones where individual parts of the earcup assembly can be replaced rather than requiring the entire unit to be discarded.

The headband (or head strap) is one of the most vulnerable parts of a pair of headphones. In classroom situations, headphones are often put on and taken off quickly, sometimes without much care.

Look for headbands that are flexible and reinforced, ideally with a metal core or high-quality composite materials. Adjustable mechanisms should feel sturdy rather than loose, as weak adjustment systems are prone to failure over time.

Cables are one of the most common points of failure. In a classroom, they are often pulled, twisted, or bent at sharp angles.

Thicker cables with proper strain relief at both ends tend to last longer. Coiled cables can reduce tangling and limit how far a student can move away from the device, but they may feel heavier. Straight cables are lighter but more prone to wear if not handled carefully.

Over-ear headphones fully enclose the ear, while on-ear headphones rest or press on top of it.

Over-ear models are generally more comfortable for longer sessions and provide better isolation from external noise. This can help students concentrate, particularly in busy classrooms.

On-ear models are often lighter and more compact, but they can become uncomfortable during extended use due to pressure on the ears.

Ear cushions come in a variety of materials, each with its own advantages.

Fabric cushions tend to be more breathable and comfortable over longer periods, but they can absorb sweat and are harder to clean.

Synthetic leather (often called “pleather”) is easier to wipe clean, making it more suitable for shared use. However, it may become less comfortable over time, especially in warmer environments.

Foam and plastic components vary widely in quality. In general, higher-density foam provides better comfort and durability.

When headphones are shared between students, hygiene becomes a practical concern rather than a minor detail.

Disposable headphone covers can help reduce direct contact with ear cushions. These are particularly useful during intensive use, such as exams, workshops, or project weeks.

Regular cleaning routines are essential. Wiping ear cushions and headbands with appropriate cleaning agents can significantly extend the lifespan of the headphones while maintaining hygiene standards.

It is advisable to establish simple procedures that students can follow, such as cleaning headphones after use or at the end of a lesson.

Without structure, cables can become tangled, adapters may go missing, and equipment can be damaged more easily. Establishing simple procedures can help prevent these issues.

For example, assigning headphones to specific workstations, numbering equipment, or using designated storage spaces can improve efficiency and accountability.

Students should also be instructed on how to handle headphones properly, including how to connect and disconnect cables and how to store them after use.

How headphones are stored has a direct impact on their lifespan.

Storage bags can protect headphones from dust and damage, especially when transported between rooms. However, they take time to use and may not be practical in fast-paced lessons.

Wall-mounted hooks or dedicated storage racks allow for quick access and encourage consistent storage habits. They also help prevent cables from becoming tangled on desks or the floor.

Headphones with detachable cables offer a clear advantage in educational settings. If a cable breaks, it can be replaced without discarding the entire headphone.

This can significantly reduce long-term costs and downtime.

Cable length should match the intended use.

Shorter cables reduce clutter and minimise the risk of tangling or tripping hazards. Longer cables offer more flexibility but can become unmanageable in busy classrooms.

Choosing a standard length across your setup can help maintain consistency, for example 1.5-2 meter.

Also consider the risk of tripping over cables or damaging them by placing chairs on top of them.

Headphone splitters allow multiple students to listen to the same audio source.

They are inexpensive, easy to use, and extremely useful in situations such as peer feedback, group listening tasks, or teacher-led demonstrations.

Having a sufficient number available can greatly increase flexibility in your lessons.

Headphones typically come with either a 3.5 mm (1/8”) or 6.35 mm (1/4”) jack plug.

In educational environments, you will likely encounter both standards across different devices. Having a sufficient number of adapters is essential to avoid unnecessary interruptions during lessons.

Adapters are small, easy to lose, and frequently needed—so it is wise to have more than you think you need. Also think of a system to keep your collection complete.

In more advanced setups, a headphone amplifier or mixer can distribute audio to multiple headphones with independent volume control.

This is particularly useful in studio-based learning environments, ensemble work with electronic instruments, or recording sessions.

Finally, consider whether spare parts such as ear cushions, cables, and headbands are available, and for how long the manufacturer is likely to support the product.

Headphones designed for professional or studio use often have better long-term support. While they may require a higher initial investment, they can be more cost-effective over time due to their repairability.

In an educational context, this can make a substantial difference when managing equipment budgets across multiple years. This also contributes to a sustainable and environmentally responsible policy.

Using the same type of headphones across a classroom or institution can simplify both teaching and technical management.

Standardisation makes it easier to provide instructions, manage equipment, and replace or repair components when needed. It also ensures a consistent listening experience for all students.

Aligning headphone specifications with other elements of your setup, such as cable length, connectors, and accessories, can further improve efficiency and reduce complexity.

Wireless headphones offer greater freedom of movement, but they introduce additional challenges such as battery management, pairing issues, and potential audio latency.

In music education contexts, particularly when working with real-time audio or recording, latency can be problematic. Reliability is also a key concern in classroom environments.

For these reasons, wired headphones are generally the more practical and dependable choice for most educational applications.

When selecting headphones for educational use, it is important to look beyond the initial purchase price.

Lower-cost models may seem attractive, but they often have a shorter lifespan and limited repair options. This can lead to higher replacement costs over time.

Higher-quality headphones are typically more durable and may offer replaceable components such as cables and ear cushions. This can extend their usable life significantly.

Considering the total cost of ownership helps institutions make more sustainable and cost-effective decisions, particularly when purchasing equipment at scale. It also contributes to a more environmentally sustainable policy.

For general use with laptops, tablets, and electronic and digital musical instruments, a set of closed-back, low-impedance headphones with fixed or detachable cables is usually sufficient. Adding a number of headphone splitters can support collaborative activities.

For aural assessments or exams, using closed-back, low-impedance headphones with a relatively neutral sound profile is recommended to support accurate listening. Closed-back models help to minimise sound leakage and reduce distraction.

In a production-focused environment, closed-back headphones with a relatively neutral sound profile are recommended. Detachable cables, replaceable ear cushions, and access to spare parts become more important. A headphone amplifier may be useful when multiple students need to monitor audio simultaneously.

When recording with microphones, closed-back headphones are essential to minimise sound bleed. Headphones should provide sufficient isolation and comfort for longer sessions. A headphone amplifier or distribution system allows multiple performers to monitor audio with appropriate volume levels.
