DELIVERY

Dispatches in 48 hours

What does "ships within 24/48 hours" mean?

In a nutshell, ships within 24/48 hours basically means that your product will be shipped out or dispatched from our warehouse within 24/48 hours after placing the order. It also indicates that the products are readily available at our warehouse and once we receive your order, we dispatch it out at the earliest either on the same day or the next working day depending on when you’ve placed your order.

What it does not mean:

A lot of our customers assume that it means their order will get delivered to them within 24/48 hours, but that’s not what it means. For an order to reach you, it can take anywhere up to 3-4 business days, depending on which part of India you are placing an order from.

For an accurate timeline, you can enter your pin code on the product page and check for an estimated date of arrival.

Koss Corporation: Innovators in High-Fidelity Sound

Founded in 1958 by John C. Koss, Koss Corporation pioneered the personal listening experience with the invention of the world’s first stereophone, the SP/3. Koss set out to capture the thrill of live music in headphones, and this dedication to audio excellence quickly made the brand synonymous with high-fidelity sound. Legendary models like the Pro/4AA, celebrated for its full-spectrum range and sound isolation, built a foundation of trust among music lovers and professionals.

Koss has since continued to redefine what’s possible in personal audio with releases like the HV/1A, capable of delivering an impressive 10-octave range, and the enduringly popular Porta Pro, known for its comfort and refined sound. Today, Koss headphones continue to inspire listeners with uncompromising sound quality, innovative design, and a timeless commitment to bringing people closer to the music they love.
