A thing to tap your toes to. For us, music isn’t a thing; it’s a place we go. We are the true believers.Koss has been bringing people closer to the music they love for more than 50 years. The first Stereophone (SP/3) in the world was created by John C. Koss and Martin Lange in 1958 and since then, Koss’ innovative products have gone from strength to strength with a range now including Full Size Stereophones, On-Ear Stereophones, In-Ear Stereophones, Ear-Clip Stereophones, Wireless Stereophones and Communication Headsets. Now, more than 50 years later….Koss’ creation has become a $2 billion industry, worldwide.Three principles serve as the foundation for the company’s success: The sound of Koss; focus on fit and breakthrough customer service. What do these principles mean?The sound of Koss: Musician, John C. Koss created “the sound of Koss” in 1958 and we have stayed true to it to this every day. The sound of Koss brings music back to life. Koss engineers are rigorous in their pursuit of the absolute best sound but it is the human listening experience that sets Koss apart.Focus on fit: We are obsessed with creating the absolute perfect fit – without it; we can’t get the perfect sound. We strive to create products that offer custom settings for every music lover. Our products couple to the ear – it’s just you and your music.Breakthrough customer service: Koss was the first to offer Limited Lifetime Warranty in 1989. Our domestic customer support staff is ready to help any listener with any issue. The Koss US factory and warehouse is based in Milwaukee Wisconsin – logistically, Koss has created an onsite inventory system that makes “out-of-stocks” virtually impossible.

In the beginning it looked nice. as soon as i started using, it started peeling and all flakes were all around whenever i used. After one week the head bridge got broken. ### ⭐⭐⭐ Um fone que só vale a pena de quiser gastar pouco! *by R***I on Reviewed in Brazil on 14 August 2020* Vamos lá. Primeiro de tudo, só compre se tiver na promoção prime (90/98 $) pois vai valer a pena. É um KOSS então dispensa comentários retóricos. Não é um porta pró mas a qualidade de Som é boa Confortável e leve nem dá pra sentir ele o que é ótimo para quem usa óculos. Tem isolador de ruído o que não é indicável para usar volume alto ao caminhar.Pontos negativos: Como visto nas fotos a primeira camada de espuma larga fácil e o que é extremamente ruim para a estética, mas o conforto continua o mesmo,pois tem a segunda camada que é a esponja mesmo de proteção.Não é dobrável como no porta pró o que é péssimo no aspecto de guardar, não tem confort zone e nem ao menos veio uma case simples. O que me incomodou foi o fato da marca do fone largar fácil fácilPor isso só comprem se tiver na promoção prime 90 98 $. Caso contrário,.comprem outro ou o porta pró mesmo. --- ## Why Shop on Desertcart? - 🛒 **Trusted by 1.3+ Million Shoppers** — Serving international shoppers since 2016 - 🌍 **Shop Globally** — Access 737+ million products across 21 categories - 💰 **No Hidden Fees** — All customs, duties, and taxes included in the price - 🔄 **15-Day Free Returns** — Hassle-free returns (30 days for PRO members) - 🔒 **Secure Payments** — Trusted payment options with buyer protection - ⭐ **TrustPilot Rated 4.5/5** — Based on 8,000+ happy customer reviews **Shop now:** [https://www.desertcart.id/products/253620651-koss-ruk-40s-24-6-headphone-white](https://www.desertcart.id/products/253620651-koss-ruk-40s-24-6-headphone-white) --- *Product available on Desertcart Indonesia* *Store origin: ID* *Last updated: 2026-05-01*
