The Happy Plugs Play (4-15 years) headphones seem to be of excellent quality. The sound quality is more than good enough for my kids, aged 7 and 9, who love to listen to music. I'm happy with the decibel limits, which give us peace of mind and we haven't had any complaint from the kids about the volume. The headphones connected via bluetooth very easily to several different devices too. We had an issue where a mistake had been made with the quantity sent, but this was resolved incredibly swiftly and communication was brilliant. I would highly recommend both the product and company.
