Ear Defenders FAQ's
Q. What do the letters printed on the Edz Kidz refer to?
A. The letters printed on the side of the Edz Kidz refer to various international safety standards:
- ANSI S3.19 - The American National Standards Institute is a private, nonprofit organization that oversees the development of voluntary consensus standards for products, services, processes, systems, and personnel in the United States. Equivalent Australian companies include SAI Global and Standards Australia.
- S3.19 is the standard introduced by the ANSI to regulate hearing protection devices. Edz Kidz meet these requirements.
- EN352-1: 1993 - This is the European Standard for hearing protection and hearing protectors, as well as protective clothing and other safety measures. Edz Kidz also meet this standard.
Q. What ages are the Edz Kidz suitable for?
A. Edz Kidz can be worn by children of all ages. However, we recommend that they are not used on children less than 6 months old. This is due to the fact that newborns heads are quite soft, and the ear defenders are a reasonably tight fit. PLEASE NOTE: This is a RECOMMENDATION only. We have had customers use Edz Kidz on children less than 6 months, with no problems whatsoever. There is no upper age limit.
Should you find the ear defenders are a bit too tight, they can be stretched slightly. Simply place two chairs back to back, and stretch the ear muffs over the two chairs. After leaving the ear muffs for a while, they will have stretched by a small amount, making them a bit less tight when worn.
Q. What payment methods do Edz Kidz currently accept?
A. We currently accept payments via All Major Credit Cards. Credit card payments are directed to our Paypal account and processed through a secure third party payment gateway. This step by step payment process is 100% secure, and is covered by Verisign's 128 bit SSL Encrypted Secure Transaction program. You do NOT need to be a Paypal member to use this option - one off payments are possible!
Q. Do the ear defenders come in different sizes?
A. Edz Kidz Ear Defenders are a "one size fits all" product. Each side of the ear muffs is adjustable in length. Once placed on the head, each ear covering can be lengthened simply by pulling the ear covering downwards. As a result, EDZ KIDZ ear defenders grow with your child!
