General Enquires

Q1: I wrote to you, but there is no reply. 

A: We usually reply very fast, within 2 working days. If you don’t get a reply,

a). please check your junk mail box.

b). if no reply in junk mail, perhaps it means your question could be answered by this list of FAQs immediately.

c). you are asking for the product lead-time, which is indicated on the product page.

d). you are asking for cable/CIEM building status, which we are unable to answer if the projected lead-time has not been reached. 

If your questions don't fall under the FAQs, kindly write in again. Sometimes we may reply slower during peak seasons, such as Black Friday, Christmas, New Year, etc.

Q2: I mailed my impression/warranty claim product to you, can you notify me once it gets delivered?

A: Due to our extremely busy schedule, we apologize that we could not actively reach out to you for package delivery confirmation. Thus it is very important for you to send in the package via a shipping method with tracking number. You could track your package, and once it is delivered, you could write to us for confirmation. We are happy to provide confirmation upon receiving your request. 


Order Enquires

Q3: I have placed the order a few days ago, why you have not shipped it out yet?

A: Quite a lot of our products (for example our cables and CIEMs) are build-to-order items, that means we don’t have ready stock for the item, and will only start building it once we have received your order. Sometimes the lead-time (from the order receiving date, to order shipment date) could be long, such as a few weeks when the ordering volume is high. For ready-stock items, such as IEMs (exclude CIEMs made into universal shapes), accessories, etc., we generally ship your order out in 2-3 working days. 

Q4: What is the lead-time for a particular item?

A: The lead-time is stated on the product page, with a dedicated tab.  

Q5: Why the lead-time changes when I check your webpage at different dates?

A: We update the lead-time, especially for our cables, on a weekly basis. It will be changed according to the current accumulated order volume. 

Q6. Can I cancel an order?

A: Non-CIEM order can be cancelled without restocking fee if the product has not been shipped at the time of cancellation request.

Once the product is shipped, the order can only be cancelled when the customer receives the product, and subsequently sends it back to us in original packaging immediately (shipping fee covered by the customer). Once we receive the returned product, we will cancel the order with a 20% restock fee of the MSRP. 

CIEM orders cannot be cancelled after one week of order placement. If the customer wishes to cancel the order within one week, there will be a SGD$60 charge for the ear impression service (if the ear impression is done with us). Overseas customers, if the ear impression has been received by us and wish to cancel the order, a basic ear impression return shipping fee will be charged. On top of the ear impression cost (if applicable), there will be an additional 20% cancellation charge (based on earphone MSRP)

Q7: What shipping methods do you provide?

A: We generally use Singpost (for registered mail) and FedEx. Occasionally we use speedpost, DHL or EMS for areas where FedEx doesn’t serve. 

Q8: How much do you charge for shipping?

A: The shipping charge will appear during check-out, once you have keyed in your delivery address.

Q9: How long does the shipping take?

A: Once the package is shipped, the shipping time depends on the shipping method you have selected. For detailed information, please refer to our shipping policy here.

Q10: Will I get a tracking number?

A: Yes, a tracking number will be sent to you via email once the package is shipped. 

Q11: Why can’t I track the package?

A: For registered mail, it usually takes Singpost 2 working days to update the tracking status. For FedEx, the tracking status is immediately shown once you receive the tracking number. 

Q12: Why Singpost tracking page shows “dispatched to overseas” and no further updates for my registered mail?

A: Once the package has left Singapore, it is handed over to your country’s national post. You can check on their websites for status updated. For certain countries, if Singpost has a collaboration for sharing the status, Singpost website may also show the status. 

Q13: I have checked with my own country’s national post, still there is no status update, or can’t even track the package. 

A: For certain countries, the tracking status is not shown online, for example U.S. and Canada. This is due to their national security reason. Check here for more detailed explanation. 

Q14: I haven’t received my package yet, after Null Audio has shipped it out for quite a while. What should I do?

A: Shipping time may vary according to different countries, as well as timing. For example year-end may have a prolonged shipping time due to holiday season. Contact us if you haven’t received it after 18 working days from the posting date. 

Q15. Do I need to pay the custom and tax?

A: Please do note that, custom and tax are charged by the respective country of the recipient, thus we are NOT liable for any such charge. We are happy to provide assistance for purchase confirmation, purchase invoice request, as well as value declaration.
