The Puro JuniorJams Wireless are on-ear headphones designed for kids. They come in several different colors, and have a max volume of 95dB to protect the listener's hearing. Unlike many other headphones, they have a daisy chain cable so two users can listen to the same audio. However, we weren't able to get it to work with our test unit. Some users also may find that the ear cups clamp the top of their ears, which can be uncomfortable. On the upside, they have a decent and sturdy build quality. They have an excellent battery performance, and can even be used passively or while charging with their included 1/8" TRS cable.

Our Verdict

6.3 Mixed Usage

The Puro JuniorJams Wireless are mediocre for mixed use. These decently durable headphones have an excited, v-shaped sound that delivers a thumpy, boomy bass. However, their sound is still suited for a variety of audio content. They also have an excellent battery performance and can be used via Bluetooth or passively with their TRS cable. While they really struggle to cut down noise like bus engines or ambient chatter, they don't leak too much audio.

Pros
  • Excellent battery performance.
  • 95dB volume limiter allows children to listen to audio at safe levels.
Cons
  • Poor noise isolation.
  • On-ear fit may not be comfortable for all wearers.
6.4 Neutral Sound

The Puro JuniorJams Wireless are passable for neutral sound. They have an excited, v-shaped sound profile that delivers intense thump and boom. However, this muddies and clutters part of their mid-range. The treble range is also bright and harsh. On the upside, their frequency response consistency is decent, although they struggle a bit more to deliver treble consistently.

Pros
  • Excellent battery performance.
  • 95dB volume limiter allows children to listen to audio at safe levels.
Cons
  • On-ear fit may not be comfortable for all wearers.
  • Inconsistent treble delivery.
6.6 Commute/Travel

The Puro JuniorJams Wireless are adequate for commute and travel. They can be a bit uncomfortable to wear for long periods. They don't block out much ambient noise, especially in the bass-range, so wearers can easily hear the rumble from bus or plane engines. On the upside, they're fairly portable, and their battery life should be long enough for most commutes or trips.

Pros
  • Excellent battery performance.
  • 95dB volume limiter allows children to listen to audio at safe levels.
Cons
  • Poor noise isolation.
  • On-ear fit may not be comfortable for all wearers.
6.7 Sports/Fitness

The Puro JuniorJams Wireless are fair for sports and fitness. Although they clamp tightly on the top of the ears, which can be uncomfortable especially when worn for long periods, they're not very stable on the head. Small movements could cause them to fall off your child's head. On the upside, when used via Bluetooth, they don't have an audio cable that can snag on something.

Pros
  • Excellent battery performance.
  • 95dB volume limiter allows children to listen to audio at safe levels.
Cons
  • On-ear fit may not be comfortable for all wearers.
  • Unstable fit.
6.3 Office

The Puro JuniorJams Wireless are unremarkable for office use. However, they most likely won't be used for this purpose by kids. Their on-ear fit can clamp on the tops of the ears, making them uncomfortable to wear for long periods. They also struggle to isolate noise such as ambient chatter around the wearer. On the upside, they have a great leakage performance, and their continuous battery life can easily last through the work day.

Pros
  • Excellent battery performance.
  • 95dB volume limiter allows children to listen to audio at safe levels.
Cons
  • Poor noise isolation.
  • On-ear fit may not be comfortable for all wearers.
4.8 Wireless Gaming

The Puro JuniorJams Wireless aren't suitable for wireless gaming. While their wireless latency is better than many other options, it still may be too high for some gamers. Also, they're only compatible with Bluetooth-enabled PCs, and can't connect to PS4 or Xbox One consoles.

6.4 Wired Gaming

The Puro JuniorJams Wireless aren't bad for wired gaming. Although they can be used on PC, PS4, and Xbox One with an analog connection, they can only receive audio, which some may find a little limiting. They can also put pressure on the tops of the ear and be uncomfortable to wear for long periods. That said, since they deliver a boomy, thumpy bass, sound effects have more emphasis in your favorite action games.

Pros
  • Excellent battery performance.
  • 95dB volume limiter allows children to listen to audio at safe levels.
Cons
  • On-ear fit may not be comfortable for all wearers.
  • Can only receive audio when connected via analog to consoles.
5.0 Phone Calls

The Puro JuniorJams Wireless are disappointing for phone calls. Their integrated microphone captures voices that sound thin and muffled, and it struggles to separate speech from ambient noise. These headphones also really struggle to reduce background noise, which can make it difficult to hear the caller on the other line.

Pros
  • Excellent battery performance.
  • 95dB volume limiter allows children to listen to audio at safe levels.
Cons
  • Poor noise isolation.
  • On-ear fit may not be comfortable for all wearers.
  • Poor integrated microphone performance.

The Puro JuniorJams Wireless have a simple but colorful look. Since they're designed for young children, they're quite small. They come in four colors: blue, green, pink, and teal.

The Puro JuniorJams Wireless are passably comfortable. The headband and cups are made of a nice material that feels nice. The headband can also expand to fit larger heads. However, due to their on-ear fit, they clamp a lot on the top of the ears. They don't have the most comfortable fit when worn for long periods, but they may be less fatiguing if your child has a smaller head.

The Puro JuniorJams Wireless have fair controls that are, for the most part, clicky and easy-to-use. There's a multi-function button that controls play/pause when pressed once, skips to the next song with two presses, and skips to the previous song with three presses. It also can answer and end calls. There's volume control, and muting the microphone while on a call requires pressing the volume down button twice. They can't be manually paired if they're already connected to a source, and there's also a delay when powering them on.

These headphones are fairly portable. Unlike the Motorola Squads 200, these headphones have ear cups that can swivel to lay flat and can be folded inwards, which helps to shrink their footprint. However, they're still a little bulky to carry around.

The Puro JuniorJams Wireless come with a thin, polyester-feeling fabric pouch. It has a drawstring but it can't be completely sealed. It should protect the headphones from dust, but that's about it.

Build Quality

The Puro JuniorJams Wireless have a decent build quality. They have faux leather padding on their ear cups and headband. There's also an aluminum-like frame under the headband's padding as well as surrounding the ear cups. Overall, these headphones feel sturdy and as if they could survive the occasional accidental drop.

Design
Stability

These headphones have sub-par stability. Although they clamp tightly on the ear, they can fall off with even low-intensity head movements. Luckily, since they're wireless, they shouldn't snag on something and pull them off the listener's ears.

The Puro JuniorJams Wireless have an excited, v-shaped sound profile that delivers a thumpy, boomy bass. However, while they sound a bit muddy, they're still fairly suitable for a variety of audio content, and they're much better-balanced than the Mpow CH1.

Frequency Response Consistency
Avg. Std. Deviation
0.6 dB

The Puro JuniorJams Wireless have decent frequency response consistency. The bass response is a little inconsistent and can be affected if your child wears glasses or has thick hair. The treble delivery varies a lot more due to their on-ear fit, and it may take the user some time to reposition them to ensure a more consistent sound.

The Puro JuniorJams Wireless have disappointing bass accuracy. Their bass is over-emphasized across the range, resulting in a thumpy, muddy sound. However, it's quite flat and even across the entire range.

These headphones have great mid-accuracy. They're overemphasized in the low-mids, which makes your mix sound muddy and cluttered. However, the mid-mid and high-mid are more flat and neutral, so vocals and lead instruments sound clear and present.

The Puro JuniorJams Wireless have okay treble accuracy. The low-treble is slightly overemphasized, which makes vocals and lead instruments sound a bit harsh. The mid treble is much more overemphasized, so sibilants like cymbals are sharp and piercing.

7.1

Dips
1.65 db

These headphones have decent peaks and dips performance. There's a peak in the high-bass that makes the mix sound overly boomy and muddy, especially as the following dip in the low-mids further weakens vocals and lead instruments. The dip in the low treble also hurts the comprehensibility and detail of vocals and lead instruments. The peak in the mid-treble, in contrast, makes sibilants like S and T sounds sharp and piercing.

These headphones have great stereo imaging. The group delay response falls below the audibility threshold, resulting in a tight bass and a transparent treble reproduction. Additionally, the L/R drivers of our test unit are fairly well-matched in amplitude, frequency, and phase response, which is important for the accurate placement and localization of objects and instruments (like voices and footsteps) in the stereo image. These results are only valid for our unit and yours may perform differently.

Like most closed-back headphones, the Puro JuniorJams Wireless' passive soundstage is poor. Since they have an on-ear fit and closed-back enclosure, their design produces a closed-off listening experience. Sound is perceived as coming from inside the wearer's head rather than in front of or around them.

These headphones have a decent weighted harmonic distortion performance. Since they're designed for children, the highest volume they can reach is 95dB, and as a result, our tests are conducted at 95dB and 85dB. There's a small peak in the low-treble when listening at 85dB. However, this can be a bit hard to hear with real-life content.

These are the settings used to test the Puro JuniorJams Wireless. They have a volume limiter that prevents them from exceeding 95dB, which has an impact on our tests as the volume is normally set to 100dB and 90dB. Our results are only valid when used in this configuration.

The Puro JuniorJams Wireless have poor noise isolation. They're unable to block out almost any noise in the bass-range, and very little noise in the mid-range, so listeners can hear the rumble of bus engines as well as people talking around them. They do a much better job of reducing treble-range noise like the hum of an AC unit, though.

These headphones have a great leakage performance. However, this may be due to their 95dB volume limit, which prevents the escaping audio from being as loud as in our conventional testing, which measures leakage at 100dB.

The Puro JuniorJams Wireless have an excellent battery performance. We measured over 19 hours of continuous battery life and almost three hours of charge time. They have an auto-off timer that powers off after 10 minutes without a connection or if the battery falls below 5%. Luckily, if the wearer runs out of battery, they can use them passively or while charging, thanks to their included TRS cable.

Differences Between Sizes And Variants

The Puro JuniorJams Wireless come in four color variants: blue, green, pink, and teal. While we tested the green variant, we expect all variants to perform similarly to our test model.

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

Compared To Other Headphones

The Puro JuniorJams Wireless are wireless on-ears for kids. Like many similarly designed headphones, they have a volume limiter that sets their max volume at 95dB to help protect the hearing of young listeners. They also come with a micro-USB daisy chain cable so that two children can listen to the same audio using different headphones. However, we couldn't get this feature to work with our test unit. If you're looking for more headphones, check out our recommendations for the best wireless on-ear headphones, the best on-ear headphones, and the best wireless Bluetooth headphones.

JBL JR300BT Wireless

The JBL JR300BT Wireless and the Puro JuniorJams Wireless are similarly performing on-ear headphones for kids. However, some may prefer one over the other. The JBL are more comfortable, and they have a volume limiter set to 85dB, unlike the Puro, which are capped at 90dB. The JBL also have a better-balanced sound profile. However, the Puro have a better battery performance with an auto-off timer. They can also be used while charging or passively, and although they have limited compatibility with PC, PS4, and Xbox One, they can receive audio on these consoles when connected via an analog connection. 

Mpow CH9 Wireless

The Puro JuniorJams Wireless and the Mpow CH9 Wireless are similarly-performing on-ear headphones for kids. The Puro are better-built and leak less noise. They have an excited sound profile, while the Mpow have a more bass-heavy sound. However, the Mpow are better-suited for phone calls as their microphone has a better performance, and they have a more stable on-ear fit.

iClever Boostcare

The Puro JuniorJams Wireless are better headphones for kids than the iClever Boostcare. The Puro are better-built, and they can also be used wirelessly, unlike the iClever. They even come with a daisy chain so two users can listen to the same audio. Also, their v-shaped sound profile is better-balanced than the iClever, especially in the mid-range.

Motorola Squads 200

The Puro JuniorJams Wireless are better kids headphones than the Motorola Squads 200. The Puro are wireless headphones that are more comfortable as well as have a better build quality. They have a very bass-heavy sound profile that some users may prefer. Their battery performance is excellent, too, as they provide over 19 hours of continuous battery life. However, the Motorola are wired headphones that have full compatibility with PC, PS4, and Xbox One.

iClever BTH02 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.

Mpow CH1

The Puro JuniorJams Wireless are better headphones for kids than the Mpow CH1. The Puro are better-built, and they can be used wirelessly, unlike the Mpow. They also come with a microphone and they leak less noise. While their sound profile is bass-heavy, it's ultimately more balanced than the Mpow.

Mpow CH6

The Puro JuniorJams Wireless are better on-ear headphones for kids than the Mpow CH6. The Puro are wireless headphones with excellent battery performance. They have better controls and a more balanced sound profile. However, the Mpow are wired, which some users may prefer, and they're more stable on the head.
