TIKTOK
I needed to buy some decent earplugs for my child to use while playing an instrument and general noise reduction. Fortunately found a 15% discount code (TIKTOK) before making purchase, so thought might be worth sharing. Not sure when it expires though.
As a side note, I recommend also buying the following accessories (which can be used with discount):
* XXS ear tips if you have small ears (like a child) for better comfort/fit. The standard tips that come with ear plugs have just 4 sizes (XS, S, M, L). I think the XXS tips only fit on the Experience and Engage models though.
* Loop Mute insert if you want the option of a further 5 dB noise reduction in certain scenarios.
