If you want a wired gaming headset with a boom microphone, choose Sennheiser EPOS GSP 300; if you need wireless headphones for everyday listening, choose Sony WH-CH520. For kids, I’d match the choice to how they’ll use them: the GSP 300 is built around game chat, while the WH-CH520 is made for Bluetooth listening and calls.
Sennheiser EPOS GSP 300 vs Sony WH-CH520 at a Glance
• WH-CH520’s biggest strength: Bluetooth listening with up to 50 hours of battery life and the ability to connect to two devices; its trade-off is that it has no headphone jack.
• The GSP 300 is an over-ear gaming headset with memory foam ear pads, an adjustable headband, and a volume wheel on the right ear cup.
• The WH-CH520 is an on-ear wireless pair with a built-in microphone, swivel earcups, adjustable headband, and soft ear pads.
• Choose the GSP 300 for gaming and voice chat; choose the WH-CH520 for wireless music, podcasts, and calls.
The GSP 300 makes most sense when the main job is gaming. Its closed acoustic design is intended to make game audio feel immersive, with deep bass for weighty effects and acoustic clarity for hearing gameplay and chat. That focus suits a child who plays on a compatible PC, Mac, Xbox One, PS4, or Nintendo Switch and wants one headset for game sound and speaking to teammates. It connects with a 3.5 mm jack, so this is a wired choice rather than a Bluetooth headset.
The boom microphone is a practical distinction. It is designed to reduce background noise while the wearer speaks, and raising the arm mutes it. That makes muting straightforward during a game or when conversation at home interrupts play. There is also a volume wheel on the right ear cup, so a quick adjustment can be made at the headset instead of reaching for a device. The headband adjusts to different head sizes and shapes, while the memory foam ear pads and ball-joint hinge are intended to improve fit and passive sound isolation.
For a child, this is the more purpose-built option if gaming and clear voice chat come first. Its over-ear style and padded cups are different from the WH-CH520’s on-ear fit, and the cable keeps the connection simple without charging the headset. The trade-off is equally clear: the wire can be inconvenient when moving around, and the GSP 300 is not the pick for someone who specifically wants wireless phone listening. Who should skip it: anyone looking for Bluetooth headphones for music, calls, or moving freely around the house.

The WH-CH520 is the more flexible everyday-listening option. It connects wirelessly over Bluetooth, has no headphone jack, and offers up to 50 hours of battery life. That combination is useful for a child who listens to music or podcasts on a phone or other Bluetooth device and would rather not keep track of a headphone cable. Its on-ear design, soft ear pads, adjustable headband, and swivel earcups are aimed at comfortable wear and easier handling.
It also has features that fit a mixed-device routine. Multipoint connection lets it connect to two Bluetooth devices at once, which can help when switching between a laptop and a phone. A built-in microphone supports hands-free calls, while the Sony Headphones Connect app offers EQ customization for adjusting the sound to personal preferences. DSEE is included to enhance the sound of compressed music files. These are listening and convenience features, not the dedicated gaming-chat setup offered by the GSP 300.
Battery life is a strong practical reason to consider it, but wireless use does mean charging is part of ownership. The listed battery life is up to 50 hours, and USB-C quick charging can provide up to 90 minutes of playback from a three-minute charge. It is also an on-ear design, not an over-ear one, so buyers should choose based on that fit preference rather than assume the two models wear alike. Who should skip it: a gamer who wants a boom mic, a wired 3.5 mm connection, or the GSP 300’s gaming-focused design.
• Best for gaming voice chat → Sennheiser EPOS GSP 300. Its noise-cancelling boom mic is made for speaking during play, and lifting the arm mutes it.
• Best for wireless listening → Sony WH-CH520. Bluetooth removes the cable, and the listed range is up to 10 meters.
• Best for long stretches away from a charger → Sony WH-CH520. It offers up to 50 hours of battery life, with quick charging as a backup.
• Best for a simple wired setup → Sennheiser EPOS GSP 300. It uses a 3.5 mm jack and does not rely on a wireless battery connection.
• Best for switching between a phone and laptop → Sony WH-CH520. Multipoint allows two Bluetooth devices to be connected at once.
• Best for an over-ear fit and passive isolation → Sennheiser EPOS GSP 300. Its memory foam ear pads cover the ears, and the design is described as improving passive noise attenuation.
• Best for adjusting music sound → Sony WH-CH520. EQ customization through the companion app lets listeners tailor sound preferences.
• Best as an over ear headphones gift for kids who game → Sennheiser EPOS GSP 300. Its headset design, boom mic, and compatibility with several gaming platforms make it the more focused gaming gift.
The phrase “best bluetooth head phones for kids” points more naturally toward the WH-CH520, since it is the wireless Bluetooth option here. That does not make it a gaming headset equivalent to the GSP 300: it has a built-in microphone, but not a boom arm that flips up to mute. And neither model is a bone conduction headphone. A shopper specifically looking for bone conduction headphones for kids should compare a different category rather than treating either of these as a match.
I’d choose the Sony WH-CH520 for a child who will mostly listen to music, podcasts, or calls without a cable. Its wireless connection, two-device pairing, and up to 50-hour battery life make it the more versatile everyday option. If the child’s main activity is gaming and team chat, I’d choose the GSP 300 instead for its boom mic and wired connection. For kids overall, my pick is the WH-CH520 when everyday wireless use is the priority.
Start with the device the headphones need to connect to. The GSP 300 has a 3.5 mm jack and is listed as compatible with PC, Mac, Xbox One, PS4, Nintendo Switch, and smartphones. The WH-CH520 uses Bluetooth and has no headphone jack. If a child’s main listening device lacks a suitable Bluetooth connection, or if a wired connection is the priority, that distinction can settle the choice quickly.
Next, think about what the microphone needs to do. The GSP 300’s boom mic is designed for gaming communication and can be muted by lifting it. The Sony’s built-in mic is suited to hands-free calls, but the product details do not describe a boom arm or a flip-to-mute control. For regular team chat, that difference matters more than the shared fact that both products include a microphone.
Fit and routine matter too. One is over-ear with memory foam ear pads; the other sits on-ear with soft pads and swivel earcups. The product details do not establish that one fit will suit every child, so consider which style they prefer. Also consider charging: the Sennheiser’s wired connection avoids battery upkeep, while the Sony’s wireless use offers freedom from a cable but requires charging. If you are comparing overall value, check the current price on Amazon rather than assuming one feature set is automatically the better deal.
For gaming chat, the GSP 300 has the more specialized setup: a wired connection, a noise-cancelling boom mic, and a lift-to-mute arm. The WH-CH520 can connect to Bluetooth devices and has a built-in microphone, but its listed features are oriented more toward everyday listening and calls.
The WH-CH520 is wireless and offers up to 50 hours of battery life, with quick charging available. The GSP 300 connects by wire, so it does not need to be charged for wireless playback.
No. The GSP 300 is an over-ear gaming headset, and the WH-CH520 is an on-ear Bluetooth pair. Neither product is described as using bone conduction.
The WH-CH520 is the more natural fit for wireless music and hands-free calls. It also supports multipoint connection to two Bluetooth devices, while the GSP 300 is more focused on wired gaming audio and voice chat.
