The iClever BTH02 are on-ear wireless headphones designed for kids. They have a compact, lightweight design that should suit most children's heads but may be uncomfortable for some kids with larger ears. They have a 94dB volume limit meant to protect young listeners' hearing and have an easy-to-understand control scheme. However, they don't feel especially sturdy and have a poor integrated microphone that clips the voice and makes it sound muffled and slightly distorted. Still, if you're looking for a pair of basic Bluetooth headphones for your child, they aren't a bad choice.

Our Verdict

5.8 Mixed Usage

The iClever BTH02 are sub-par for mixed usage. They have a plasticky build, so they may not be durable enough for use by children who like to play rough with their toys. Their on-ear fit isn't very adjustable and may not be comfortable for all listeners. On the plus side, they have a long battery life that should last throughout long road trips and don't leak that much noise.

Pros
  • Long battery life.
  • Simple control scheme.
  • 94dB volume limiter allows children to listen to music safely.
Cons
  • Inconsistent audio delivery.
  • On-ear design may not suit all head shapes.
  • Bad noise isolation performance.
  • Flimsy build quality.
5.7 Neutral Sound

The iClever BTH02 are middling for neutral sound. They have a boomy sound profile that muddies vocals and lead instruments. They have an underemphasized treble response that dulls higher notes and makes sibilants sound somewhat lispy. They also slightly struggle to deliver audio consistently.

Pros
  • 94dB volume limiter allows children to listen to music safely.
Cons
  • Inconsistent audio delivery.
  • Sub-par stereo imaging capability.
5.9 Commute/Travel

The iClever BTH02 are inadequate for commuting and travel. They're somewhat uncomfortable and a little bulky. They also don't block out much in the way of ambient noise, especially in the bass range, so wearers may hear the rumble of bus engines as well as chatter from fellow travelers. That said, they have a very long battery life that should be more than enough to last overnight trips.

Pros
  • Long battery life.
  • 94dB volume limiter allows children to listen to music safely.
Cons
  • On-ear design may not suit all head shapes.
  • Bad noise isolation performance.
  • Flimsy build quality.
6.4 Sports/Fitness

The iClever BTH02 are passable for sports and fitness. They aren't very tight on the head and have a somewhat unstable fit, so they may fall off with even moderate head movements. Thankfully, they have a basic control scheme that's easy to use, even when on-the-move.

Pros
  • Simple control scheme.
  • 94dB volume limiter allows children to listen to music safely.
Cons
  • Unstable fit.
  • Flimsy build quality.
5.8 Office

The iClever BTH02 are sub-par for office use, but since they're designed for children, it's unlikely that they'll be used for this kind of scenario. They're not especially comfortable and let in a lot of ambient noise, which can be annoying. They leak very little audio and last for more than 50 hours on a single charge, so they should have no trouble lasting the workweek.

Pros
  • Long battery life.
  • 94dB volume limiter allows children to listen to music safely.
Cons
  • Inconsistent audio delivery.
  • On-ear design may not suit all head shapes.
  • Bad noise isolation performance.
4.5 Wireless Gaming

The iClever BTH02 aren't suitable for wireless gaming since they can't connect wirelessly to Xbox One and PS4 consoles and have high wireless latency on PC.

6.1 Wired Gaming

The iClever BTH02 are mediocre for wired gaming, as long as their user doesn't intend on using their integrated microphone. The included 1/8" TRS cable allows users to receive audio on all systems with an AUX port, and their bass-heavy sound profile should give some in-game sound effects extra emphasis. Unfortunately, they aren't especially comfortable.

Pros
  • 94dB volume limiter allows children to listen to music safely.
  • Support for passive audio playback.
Cons
  • Sub-par stereo imaging capability.
  • On-ear design may not suit all head shapes.
5.2 Phone Calls

The iClever BTH02 are poor for making phone calls. Their integrated mic clips the user's voice and makes it sound unnatural and muffled. It also struggles to isolate speech from even moderately-loud background noise. They let in a lot of ambient noise, which can make it difficult to focus on phone conversations.

Pros
  • 94dB volume limiter allows children to listen to music safely.
Cons
  • Poor microphone recording quality.
  • Bad noise isolation performance.
  • 5.8 Mixed Usage
  • 5.7 Neutral Sound

These headphones are passably comfortable. They're very lightweight and have a flexible, well-padded headband. Unfortunately, if the wearer has a wide head or unusually shaped ears, they may feel some fatigue during long listening sessions, as the ear cups don't distribute pressure very evenly.

The iClever BTH02 have a simple control scheme that's decently easy to use. They feature a control pad on the left ear cup with buttons for volume adjustment, pausing and playing media as well as answering and ending calls, and a dedicated power on/off button. Unfortunately, there's no way to manually put the headphones into a Bluetooth pairing mode and the volume buttons can be a little hard to tell apart. Thankfully, the switches themselves are quite clicky. There are audio prompts for reaching the max volume level, powering them on and off, and successful wireless pairing.

Build Quality

The iClever BTH02 are reasonably well-built. Most of the headphones' structure is made of somewhat dense plastic, and the ear cups and headband are lined with soft-feeling faux leather. The ear cups' yokes and hinges are the weakest points and could break if they're dropped. Consider the Puro JuniorJams Wireless or Mpow CH6 if you're looking for sturdier-feeling kids headphones.

5.5
Design
Stability

The iClever BTH02's stability is middling. They don't clamp the head very tightly and may fall off the listener's ears even with moderate head movements. That said, their wireless design reduces the chances of an audio cable snagging on something and yanking them off the user's head. If you want a more stable pair of kids' headphones, check out the Mpow CH9 Wireless.

Sound
Sound
Sound Profile
Bass Amount
2.82 dB
Treble Amount
-6.64 dB

The iClever BTH02 have a bass-heavy sound profile. Their overemphasized bass response adds boominess to some mixes and muddies vocals and lead instruments, but may please young fans of genres like EDM. Meanwhile, their underemphasized, uneven treble range flattens the detail on some higher notes and makes sibilants sound dull and lispy. If you're looking for kids headphones with a better-balanced, more neutral sound profile, consider the JBL JR300BT Wireless.

6.3
Sound
Frequency Response Consistency
Avg. Std. Deviation
0.81 dB

These headphones have unremarkable frequency response consistency. Their bass and treble delivery can vary pretty significantly based on their fit and positioning, so it can be difficult to achieve a consistent listening experience, especially if the user has long hair or wears glasses.

High-Bass
7.64 dB

These on-ears have mediocre bass accuracy. The mid-bass and high-bass ranges are overemphasized, adding a bit of extra thump and kick to genres like EDM, but also generating boominess in some mixes. Since their bass delivery is dependent on their fit and positioning, the wearer's listening experience can vary.

High-Mid
-0.48 dB

The mid accuracy of these on-ears is good. While the overemphasis in the low-mids slightly muddies vocals and lead instruments, the rest of the range is mostly well-balanced. This results in clear, present vocals and leads. There's a slight mismatch between the L/R drivers of our unit in this area in the frequency range.

Sound
Treble Accuracy

7.68 dB
Low-Treble
-7.27 dB
Mid-Treble
-3.46 dB
High-Treble
-12.85 dB

The iClever BTH02 have poor treble accuracy. They're underemphasized across the entire frequency range, so vocals and lead instruments are missing some detail while sibilants sound dull and lispy. That said, their treble response is heavily dependent on their fit and positioning, so your real-world experience may vary.

6.6
Sound
Peaks/Dips
Peaks
2.19 dB
Dips
1.89 dB

The peaks and dips performance of the iClever BTH02 is okay. There's an extended bump from the mid-bass to low-mid range that generates some boominess and muddies vocals and lead instruments. A dip in the mid-mids pushes vocals and lead instruments toward the back of the mix. The peak in the high-mids and following dip in the low-treble makes those vocals and lead instruments sound alternatively harsh and veiled. The sharp rise in the mid-treble range gives sibilants a piercing quality.

The iClever BTH02 deliver sub-par stereo imaging performance. Their weighted group delay falls mostly beneath the audibility threshold, resulting in tight bass and transparent treble. Unfortunately, the L/R drivers show notable frequency and phase mismatch as well as minor amplitude mismatch. This means that the headphones struggle with accurately placing objects in the stereo image, like voices and footsteps. These results are only valid for our test unit, and others may perform differently.

The iClever BTH02 have a bad passive soundstage, which is normal for closed-back headphones. Their on-ear fit only partially interacts with the outer-ear, which is vital in creating an out-of-head, speaker-like listening experience. Sound is likely to be perceived as coming from the inside of the listener's head rather than all around them.

The weighted harmonic distortion performance is unremarkable. There's distortion present throughout the entire frequency range regardless of volume level, especially in the low-treble, which has a slight impact on their ability to reproduce audio cleanly.

Note:These headphones have a 94dB max volume limiter meant to protect young listeners' hearing, so this test was conducted at 94dB and 84dB rather than the conventional 100dB and 90dB.

These are the settings used to test the iClever BTH02. These headphones have a volume limiter that prevents them from exceeding 94dB, which does have an impact on our tests where volume is normally set to 100dB and 90dB. Also, testing was done using a Bluetooth 4.2 dongle rather than the conventional Bluetooth 5.0 dongle due to connectivity issues. Our results are only valid when they're used in this configuration.

The passive noise isolation performance of these headphones is bad. They don't isolate the listener from ambient noise in the bass and mid-range, so sounds like bus engines and background chatter can be heard while wearing them. They do a slightly better job of filtering out higher-pitched ambient sound, such as the hum of a nearby AC unit.

The iClever BTH02's leakage performance is great, though this may be in part due to their 94dB volume limiter, which prevents escaping audio from being as loud as it would be in conventional testing, which is conducted at 100dB.

You can listen to them as they charge, which is handy, as they take over 3 hours to completely recharge. If young listeners aren't in the mood to wait, the headphones support passive audio playback via the included 1/8" TRS cable.

Differences Between Sizes And Variants

The iClever BTH02 comes in four different color variants: 'Green', 'Blue', 'Pink', and 'Blue/Orange'. We tested the 'Green' variant, and you can see its label here. We expect the other variants of these headphones to perform similarly overall.

If someone comes across a differently-configured iClever BTH02 model, let us know in the discussions below so that we can update our review.

Compared To Other Headphones

The iClever BTH02 are basic kids' headphones. They have a long battery life, a simple control scheme, and a 94dB volume limit to prevent young listeners from damaging their hearing, but they feel somewhat flimsy and don't block out much in the way of ambient noise. If you're looking for alternatives, take a look at our recommendations for the best wireless on-ear headphones, the best wireless Bluetooth headphones, and the best on-ear headphones.

JBL JR300BT Wireless

The JBL JR300BT Wireless are better wireless kids headphones than the iClever BTH02 Wireless. The JBL have a more comfortable on-ear fit, a better-balanced sound profile, are easier to carry around, and much lower wireless latency. However, the iClever are better-built, have almost five times the single-charge battery life of the JBL, and offer support for passive audio playback on a wired connection.

Motorola Squads 200

The iClever BTH02 Wireless and the Motorola Squads 200 are kids headphones, but depending on preferences, some users may prefer one over the other. The iClever are Bluetooth headphones that are significantly more comfortable, and better-built. Their battery performance is great too and they have a continuous battery life of over 50 hours. However, the Motorola are wired headphones that can be used with full-compatibility with PC, PS4, and Xbox One. They also have a better-performing microphone.

Mpow CH9 Wireless

The Mpow CH9 Wireless are better on-ear headphones for kids than the iClever BTH02 Wireless. The Mpow have a more stable fit and a more consistent audio delivery. Also, their microphone has a better overall performance. That said, the iClever are better-built, and they have longer continuous battery life.

Mpow CH6

The iClever BTH02 Wireless are better kids headphones for mixed usage than the Mpow CH6. The iClever have a more comprehensive control scheme and deliver audio more consistently. They're wireless headphones with a 50-hour plus battery life, so running out of charge isn't a major concern, though they can be used to receive audio passively with their included 1/8" TRS cable. Meanwhile, the Mpow are better-built, have a superior integrated microphone, and block out more ambient noise.

Puro JuniorJams Wireless

The Puro JuniorJams Wireless are better wireless headphones for kids than the iClever BTH02 Wireless. The Puro seem better built and have a more neutral sound profile. While their continuous battery life isn't as long as that of the iClever, they have an auto-off timer to help them conserve battery life when not in use. However, the iClever's integrated mic has significantly better performance, although it's still disappointing overall.

iClever Boostcare

The iClever BTH02 Wireless are better headphones for kids than the iClever Boostcare. The BTH02 are better-built, and they can be used wirelessly, unlike the Boostcare. While the BTH02 have a bass-heavy sound profile, it's still more neutral than the Boostcare's unbalanced sound profile.
