Shipping FAQ's

Which countries do you ship to?

We are generally able to ship to most countries via DHL Express, and many countries via Standard Shipping. You may clarify with our team to see whether Standard Shipping is available to your country.

*Note: We can only do Standard Shipping for the UK, India and Russia. We can only do Express Shipping to Africa, Argentina, Hawaii, Kuwait, Mauritius, Montenegro and Sri Lanka, to name a few.

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.

How long does it take to process my order after it is placed?

For in-stock products, your order will be shipped within 3 working days. You may check with our staff regarding the in-stock status of any products. 

Customized items will take a longer time. Please contact our staff for more information.

On normal non-sale days, once your parcel has been shipped out:

  • For Standard Shipping, it takes about 2-3 weeks for items to be delivered after shipping out. For some countries, it might take up to 2-3 months, depending on your country and its customs. The duration for transit is something beyond our control. Linsoul will not be making refunds for such cases. Please consider an upgrade to DHL Express or keep the waiting time in mind.
  • For Express Shipping, it takes about 3-7 days for items to be delivered after shipping out.

*Note: Timings might be affected due to festive seasons or other unforeseen circumstances

What happens if the parcel has been shipped but not delivered?
