These on-ears are made from plastic and give off a robust first impression thanks to their flexible bracket construction. Despite this flexible element, the headphones ensure a good level of stability when worn, despite the fact there is no padding along the inner side of the headband. In fact, they can even be worn by adults. This is not only down to the fact they have good levels of flexibility and soft padding at the earpieces, but also the seven-stage incremental size adjustment. This also means that these headphones can grow alongside your children, serving them well for a longer amount of time.

When it comes to battery life, you can expect up to 12 hours of operation after a charge. When used with iOS devices, battery status is displayed next to the Bluetooth symbol. If the battery is empty, it takes between two to three hours to fully charge using the included USB cable. Alternatively, these headphones can be used in a wired fashion with no need to charge them, although a cable is not supplied for this purpose.

Device Control

These on-ears support Bluetooth 4.2 and offered ranges of up to ten metres consistently when tested. This test was carried out with a variety of iOS and Android devices, with the result proving respectable enough and allowing children plenty of freedom of movement when listening. Pairing is simple and can be done by holding down the central remote button on the right-hand earpiece. The button can also be used to switch the system on.

When connection is established, the button can be then pressed to start and stop playback, as well as accept and end phone calls. By double-clicking the button, you can jump forward to the next title in a playlist, while triple-clicking lets you backtrack to the previous one. Plus and minus buttons are also on offer here for volume control, with their simple design making operation of these headphones incredibly user-friendly. Speech intelligibility of these headphones is also decent when using for phone calls, with clear voices on either end of the line.

Volume Limit

These Tinyphones Wireless headphones have a volume limit in place to protect children from suffering any damage to their hearing when listening at higher volumes. This protective function limits the maximum output of the headphones to 85dB, which isn’t so low that music can be still be enjoyed when listening in noisy environments. However, when in quieter settings, this volume might prove a little too high for some, so keeping an eye on levels for younger children is recommended. As the limit is set via an internal circuit, it is consistently active and cannot be turned off.

Sound

These Tinyphones Wireless headphones boast bass-emphasised tuning, with a focus on the upper bass range rather than the lower frequencies. Regardless, the lower range itself is impressive and charged. In contrast to this, the upper range is somewhat under-represented, resulting in an ultimately dull sound profile. However, there’s a clear and balanced mid-range at work here, meaning that a wider range of device applications compensate for the sound shortfalls. Vocals enjoy an earthy and warm tonality, while contemporary pop productions benefit from a dynamic energy and heavy presence in the bass ranges.

JVC’s Tinyphones Wireless headphones are defined by their adaptability, robust construction and easy-care maintenance, not to mention their comfortable fit. The impressive Bluetooth range ensures children wearing them have plenty of freedom of movement, while the handy volume limit ensures little ones are protected from hearing damage. From a sound performance point of view, a more balanced tuning would have been welcome, although these wireless on-ears can be used to enjoy pretty much any music genre. Ultimately, the price/performance ratio of these children’s Bluetooth headphones is extremely good.
