THUNDERPLUGS / Thunderplugs x Happy Ears - Original Medium

Variations

"Thunderplugs x Happy Ears" are high-fidelity concert earplugs born in Sweden. Officially endorsed by the world's largest music festivals, this special edition model retains the original's superior noise reduction, comfortable fit, and natural sound quality while enhancing its design and portability. Perfect for everyday use, concerts, festivals, and work sites.

■ Uniform Sound Attenuation and Clear Sound Quality
To eliminate the issues commonly associated with standard earplugs—such as muffled sound or the loss of specific frequencies—we have achieved extremely uniform sound attenuation. While reducing overall sound levels by 25 dB (CE certified), these earplugs deliver the natural resonance of vocals and instruments directly to your ears.

Sound levels at live venues often exceed 100 dB. Even brief exposure can strain the inner ear, potentially leading to tinnitus after the show or, in the long term, hearing loss that is difficult to recover from.

By using Thunderplugs x Happy Ears, you can safely protect your hearing from dangerous sound levels without compromising the quality of the music.

■ Unique Oval Design
Featuring an “oval” design tailored to the shape of the human ear canal, it provides the right balance of seal and sound insulation. Unlike urethane earplugs that expand inside the ear, these do not cause pressure or pain even during prolonged wear. They are also discreet when worn, blending seamlessly into live concert and festival environments.

■ Global Adoption
Recommended as the official earplugs at major global music events such as SXSW (USA), Lollapalooza (USA), and Reeperbahn Festival (Germany). Their reliability in balancing sound quality and hearing protection is highly regarded by many event organizers.

Gently pinch the stem of the earplug and insert the large oval tip into your ear.

If you are using these for the first time, be careful not to push the earplug too far into your ear canal. Doing so may make it difficult to remove.
Adjust the fit until the earplug sits naturally and comfortably in your ear. The earplug will naturally seal against the base of your ear canal. After a few uses, insertion and removal will become very easy.

■ Durable design that lasts about 2 years with proper cleaning
Thunderplugs x Happy Ears can be washed entirely under water. Unlike disposable types, they can be used hygienically for an extended period. The one-piece design requires no replacement parts, making them highly durable. With proper care, they can be reused for about 1–2 years (or several years with occasional use), making them a cost-effective product.
If they become dirty, gently wash them with lukewarm water and soap, dry them thoroughly, and then store them in the case.

■When to Replace
To maintain safe sound insulation, please consider replacing them with a new product if you notice any of the following conditions:
・Physical deterioration, such as cracks in the material
・You feel that sound insulation or the sense of seal has decreased
・There has been a change in the fit when worn
