Features

Active Noise Cancelling (ANC) Function

These headphones do not feature active noise cancellation (ANC). This means they rely solely on the physical design of the earcups to block out external noise. While the over-ear design provides some passive noise isolation, it is not as effective as ANC, which actively reduces ambient sounds using microphones and signal processing. This function is not available.

Transparency Mode Function

Transparency mode is not available on these headphones. This function allows users to hear external sounds without removing the headphones, which is useful for safety in urban environments or for having conversations. The absence of this feature means users must remove the headphones to hear their surroundings clearly. This function is not included.

Multipoint Pairing Function

Multipoint pairing, which allows the headphones to connect to two devices simultaneously, is not supported. Users will need to manually disconnect from one device before connecting to another. This can be inconvenient for those who frequently switch between devices. This function is not available on this model.

Customizable EQ Function

These headphones do not offer a customizable EQ function. Users cannot adjust the sound profile to their preferences, meaning the audio output is fixed. This limits the ability to fine-tune bass, treble, and mid-range frequencies for different music genres or personal tastes. This function is not included.

Detachable Cable Function

The product information indicates that the headphones come with a 3.5mm audio cable, but it does not explicitly state whether the cable is detachable. Without a detachable cable, if the cable is damaged, it cannot be easily replaced without needing to repair or replace the entire unit. This function is not confirmed.

Folding Design Function

The headphones feature a folding design, making them compact and portable for storage and travel. This function allows the headphones to be easily transported in a bag or backpack when not in use, protecting them from damage. The foldable design and soft PP material make these kids' headphones compact and portable.

Ranked #48 out of 100 products in Category
3.4
Overall Rating

The Tronsmart KH02 Kids Headphones are a budget-friendly option for parents seeking to protect their children's hearing. While sound quality may not match higher-end models, the volume limiting feature and durable design make them suitable for young users. Expect a lifespan of a few years with careful use.

Sound Quality (Frequency Response)
3.0
The headphones offer a standard frequency response suitable for general listening. While the sound quality is adequate for children's content, audiophiles may find it lacking in depth and clarity. The 40mm drivers provide sufficient sound for the intended use case.
Comfort and Fit
4.0
Designed with children in mind, the headphones feature imitation protein leather earpads and an adjustable headband for a comfortable fit. The lightweight design ensures extended wear without fatigue. The adjustable headband offers four levels of adjustment for a secure fit.
Noise Isolation/Cancellation
2.0
These headphones offer basic noise isolation due to their over-ear design. However, they lack active noise cancellation, making them less effective in very noisy environments. This is a limitation for use in extremely loud environments.
Bluetooth Codec Support
3.0
The headphones support standard Bluetooth connectivity, ensuring compatibility with most devices. While the specific Bluetooth codec is not specified, it likely uses SBC, which provides acceptable but not high-fidelity audio quality. The wireless connectivity technology ensures faster matching.
Battery Life and Charging
4.5
With up to 45 hours of battery life, these headphones are suitable for long trips and extended use. A 2-hour charging time is reasonable, and the inclusion of a 3.5mm audio cable allows for continued use when the battery is depleted. This is a great feature for travel.
Microphone Quality (for Calls/Conferencing)
3.5
The built-in HD microphone provides clear voice quality for hands-free calls and online courses. While not professional-grade, it is adequate for the intended use, ensuring effective communication in typical environments. The built-in premium omnidirectional microphone provides clear sound.
Manufacturer Reliability and Warranty
3.0
Tronsmart has been in the audio industry for over 10 years, indicating some level of reliability. However, as a less established brand compared to top-tier manufacturers, customer support and warranty claims may not be as seamless. The headphones come with a warranty card.
Cost Performance
4.0
At $19.99, these headphones offer good value for the price. The combination of volume limiting, durable design, and wireless/wired modes makes them a cost-effective option for parents seeking affordable and safe headphones for their children. This is a great value for the features offered.
