I have over 25-years in IT. Every once-in-awhile I get concerned about Kids Headphones, so I started testing a few [Classroom Kids Headphones]. I typically use Headphones in the $350 - $500 Range [Audiophile Grade], with a nice Flat Balanced Engineered Tone.I was drawn to these Headphones by the Questions I ask of the Amazon Rufus AI:_________________Do these Ailihen headphones have a noise limiter of 85dB?No, they have a 93dB volume limiter to protect kids' hearing, not 85dB. The 93dB limit ensures clear sound while safeguarding their ears.Do these Ailihen headphones restrict audio at safe levels for children?Yes, the product description states that these headphones have a 93dB volume limiter to protect kids' hearing while ensuring clear sound quality.Is this Ailihen headphone certified for children?While the product description doesn't mention any specific child safety certification, it does state that the headphones have a 93dB volume limiter to protect kids' hearing.Does WHO Certify Headphones for 93dB compliance?There is no specific certification from the World Health Organization (WHO) for headphone 93dB compliance. However, some relevant information:- The WHO provides guidelines on safe listening practices, recommending that listening levels be limited to 85 dB for no more than 8 hours per day to avoid hearing damage.- Many headphone manufacturers design their products to limit maximum sound output to 85-93 dB to align with WHO guidelines and regulatory standards.- The European Union's Safety of Toys directive sets a limit of 85 dB for toy headphones and personal music players intended for children.- Some headphone models marketed for children or with volume limiting features may explicitly state compliance with 85 dB or 93 dB limits, but this is not a universal certification.Are these Ailihen headphones suitable for both children and adults?The product description mentions that these headphones are suitable for kids and teens. However, it does not explicitly mention if they are suitable for adults.

I tested these on my Dell Latitude 7410 Chromebook, and was pleasantly met with a nice balanced near [Audiophile Grade @ 93dB Limited] sound stage and imaging [location of Objects and Vocales]. See the Image below for a reference.Sadly, I do not find the same results with many Manufacturers [I just tested several Different Brands yesterday that nearly exceeded 110dB - Damaging to Children!], not to say there are also a large number who take this issue seriously, you just have to do the research prior to purchasing. You can also ask the World Health Organization (WHO) for Kids Headphones with 93dB compliance.There should be a Federal Mandate forcing this issue, for the Children's Safety! The European Union's Safety of Toys directive sets a limit of 85 dB for toy headphones and personal music players intended for children. The United States should at least have as many restrictions.Ailihen is world renowned for quality Engineering and Design, with a beautifully balanced 93dB Limited Tuning.Personally, I highly recommend these Kids Headphones.
