How much does shipping cost?

We have two shipping methods - Standard Shipping and Express Shipping.

Standard Shipping is free for most countries, while Express Shipping via DHL Express is 10-35USD depending on your country. If your order is over 200USD, DHL Express Shipping is free*.

*For some countries, DHL Express is only free for orders above $239USD. Large items such as headphones (e.g. HarmonicDyne Zeus, Gold Planar GL2000, and etc.) are exceptions as well.

Shipping fees exclude import taxes or processing fees that might be applicable for your country. Linsoul is not responsible for any form of such fees.
