iClever BTH02 Wireless Headphones Review

The iClever BTH02 are colorful headphones meant for children. They have small ear cups made of brightly-colored plastic and are available in a range of vivid color schemes to suit young listeners' tastes.

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.

The iClever BTH02 are acceptably portable. Their ear cups fold in but don't swivel, so they're bulkier than alternatives like the JBL JR300BT Wireless.

These headphones don't have a case or pouch.

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.

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.

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.

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.

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.

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.

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.

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.

These headphones don't have any virtual soundstage features.

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.

These headphones have an integrated mic.

The integrated microphone has poor recording quality. It makes your voice sound fairly unnatural, distorted, and boomy. It also cuts out at certain moments during calls.

The integrated microphone has mediocre noise handling capability. It struggles to isolate speech from moderate background noise, so these headphones are best suited for making calls in a quiet environment.

The iClever BTH02 have great battery performance. They last almost 52 hours on a single charge, which comfortably outlasts their advertised claim of 20 hours. 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.

These headphones don't have a companion app.

The Bluetooth connectivity of these headphones is alright. They support Bluetooth 5.0 but not NFC or multi-device pairing. Latency on PC and iOS systems is too high for most users to find them ideal for gaming or streaming movies, but they perform fairly well with Android devices. That said, apps and devices compensate differently for latency, so users' real-world experiences can vary.

The iClever BTH02 only support Bluetooth wireless connections.

These headphones come with a 1/8" TRS cable that allows for passive audio playback but has no microphone compatibility. They also come with a micro-USB cable for charging. If you're looking for wired-only headphones for kids, check out the iClever Boostcare.

These headphones can connect wirelessly to Bluetooth-enabled PCs for full audio and microphone compatibility, though their latency is too high for gaming. When you plug their 1/8" TRS cable into a PS4 controller, users only receive audio.

The iClever BTH02 can only receive audio when you plug their 1/8" TRS cable into an Xbox One controller. If you're looking for a pair of kids headphones that have full analog and audio compatibility with the Xbox One, try the Motorola Squads 200.

The iClever BTH02 don't have a base or dock.
