If you want adjustable sound for music and focused listening, choose CCA KZ Castor Pro; if you need a wired IEM with an inline mic and a wrap-around fit for a kid, choose Piluyaa Gaming Headphones IEM. Both use a 3.5 mm connection, but their strengths point to different daily routines.
CCA KZ Castor Pro vs Piluyaa Gaming Headphones IEM at a Glance
• CCA KZ Castor Pro: Two 10 mm dynamic drivers and four tuning switches offer up to 16 sound profiles; the trade-off is a wired design with no inline microphone listed.
• Piluyaa Gaming Headphones IEM: A lightweight 2.3 g earpiece, memory ear hooks, and an inline mic suit calls, gaming, and active use; the trade-off is one dynamic driver and no volume control.
• Connection: Both are wired and use a 3.5 mm jack, so neither is a wireless pick.
• Sound adjustment: CCA has four switches for changing low- and high-frequency tuning; Piluyaa does not list adjustable sound profiles.
• Choose CCA if sound customization and a dual-driver setup matter most.
• Choose Piluyaa if a child needs a mic, call and track controls, and a more secure wrap-around design.
The Castor Pro is built around two 10 mm dynamic drivers: one for mid- and high-frequency sound and another dedicated to low frequencies. That arrangement gives it a distinct appeal for listeners who want weight in the bass but also want vocals and instruments to remain present. CCA also lists a 20–40,000 Hz frequency range and 103 dB sensitivity. Those figures describe the product’s audio specifications; they do not, by themselves, guarantee that every listener will prefer its tuning.
The most unusual feature here is the set of four tuning switches. They adjust low and high frequencies and allow up to 16 sound profiles, so the Castor Pro gives its owner options instead of locking them into one sound signature. That could suit a teenager or adult who listens to varied genres and enjoys changing the balance between bass, mids, and treble. Its rounded-tip, in-ear design and ergonomic shape are intended for a secure fit during longer listening sessions.
This is a wired IEM with a 3.5 mm jack, a detachable 2PIN-C cable, and a listed remote with volume control. It has no noise-control feature listed, and the data does not identify an inline microphone. That matters if calls or voice chat are a priority. The listed age range is adult and teenager, so for a younger child I would pay close attention to fit and handling rather than assume it is designed for them.

Who should skip it: Skip the Castor Pro if you want a listed inline mic for calls, a wrap-around ear hook, or a wireless design.
Piluyaa Gaming Headphones IEM: Who It's For
Piluyaa takes a more straightforward approach: a single dynamic driver, a 3.5 mm wired connection, and an inline microphone with remote buttons for answering or ending calls and controlling playback. The remote supports play, pause, and track skipping, but volume control is not supported. That distinction is easy to overlook, and it may matter if the listener expects to adjust volume from the cable.
Piluyaa describes the sound as bright and clear, with bass and treble, and lists a frequency range of 20 Hz–20,000 Hz. It is a one-driver design, without the Castor Pro’s tuning switches. That makes it simpler, but there is less flexibility for someone who wants to adjust bass or treble. The 3.5 mm plug is described as compatible with devices that have a matching audio connection, including phones and computers; the specific device still needs a suitable jack.
Who should skip it: Skip Piluyaa if you want cable-based volume control, multiple sound profiles, or the Castor Pro’s dual-driver arrangement.
• Best for changing the sound balance → CCA KZ Castor Pro. Its four switches create up to 16 profiles, including adjustments to low and high frequencies.
• Best for an inline mic → Piluyaa Gaming Headphones IEM. The mic is positioned on the cable, and the remote handles calls and playback.
• Best for a kid who needs a secure-feeling fit → Piluyaa. Its ear hooks wrap around the ears, and the package includes three pairs of silicone tips. Check fit rather than assuming one tip will work for every child.
• Best for a dedicated low-frequency driver → CCA. Its dual 10 mm setup assigns one driver to low frequencies and another to mids and highs.
• Best for cable volume control → CCA. Volume control is listed for its remote; Piluyaa’s remote does not support volume adjustment.
• Best for calls and track skipping → Piluyaa. Its inline controls cover calls, play, pause, and skipping tracks.
• Best if you want a detachable cable → CCA. The Castor Pro lists a 2PIN-C detachable cable; Piluyaa’s cable is described as a four-core OFC wire, with no detachable connection listed.
• Best if you are avoiding wired headphones → Neither. Both models use wired connections and a 3.5 mm jack.
Buying Considerations
Think about who will use the headset and what they do with it. For a child’s gaming sessions or calls, Piluyaa’s inline mic and call controls are useful features on paper. Its ear hooks may also help keep the earpieces in place during movement. However, the remote does not control volume, so the listener will need to adjust volume on the connected device. The Castor Pro offers cable volume control but does not list a microphone, which makes it the less obvious pick for voice chat.
Fit deserves attention, especially for kids. Piluyaa includes three pairs of silicone tips and uses a wrap-around ear design. The Castor Pro has an ergonomic in-ear shape with rounded tips, but its listed age range is adult and teenager. Neither sheet specifies a child-sized fit, so I would not treat either as a guaranteed fit for every younger listener.
The activity also matters. Piluyaa’s ear hooks and light earpieces may make it a more practical option for movement than a design without listed hooks. But neither data sheet lists an IP water-resistance rating. If you are searching for in ear earbuds ipx8, neither product’s provided specifications establish that level of water protection. I would not assume either is suitable for swimming or heavy exposure to water. Similarly, someone looking for the best sweatproof headphone for yoga should note that sweat resistance is not specified for either model.
Battery life is not a differentiator because both are wired and neither has a battery-life figure listed. If your search is for the best long battery life wireless earbuds for office, these two do not meet the wireless part of that brief. For office use where a wire is acceptable, the choice instead comes down to whether you value adjustable sound profiles or an inline mic and call controls.
Finally, decide whether customization is actually useful to you. CCA’s switches give the listener more ways to alter the sound, but that advantage matters most if the owner plans to experiment with those profiles. Piluyaa offers a simpler control set and a mic, which may be more useful for routine calls and gaming. If price will decide the purchase, check the current price on Amazon using the page’s button rather than relying on an outdated figure.
My Verdict
I would choose Piluyaa Gaming Headphones IEM for a kid who needs wired gaming audio, an inline mic, and a wrap-around fit. Its three included tip pairs and call controls make its intended everyday role easy to understand, while the lack of volume control is a real limitation.
Piluyaa is the more practical fit on paper for a child using a wired headset for calls or gaming: it has an inline mic, call and playback buttons, and wrap-around ear hooks. The listed age range is adult, so check comfort and fit for the individual child.
No. Its inline remote supports answering or ending calls and controlling playback, including skipping tracks, but volume control is not supported. Volume must be adjusted using the connected device.
No. Both are wired models with 3.5 mm connections, and neither sheet lists a battery. They do not offer wireless battery life.
Neither product’s provided specifications list an IPX8 rating or sweat resistance. Do not assume either is suitable for swimming or use where water or sweat protection is required.
