Our Verdict
JBL JR300BT Wireless
Puro JuniorJams 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.
