Our head-office is in Mumbai; however, we don’t have a showroom or physical stores. We're an online company - we distribute our products online all over India via a distributed warehousing system - we have warehouses in 8 locations. Since our products are technical and used for solving specific acoustic problems, they do not attract walk-in customers. If you want to buy our products, just place your order online or reach out to us via the contact forms.
We do not offer Cash on Delivery. Our products are extremely large and bulky - you can fit a human being into most of our boxes. As a result, one of the highest costs in running this company is the money paid to courier companies like Fedex, XPressBees, etc, which runs into crores of rupees annually. If we allowed COD and the buyer changes their mind and refuses to pay during delivery, we incur double shipping costs (a) for sending the product to the buyer + (b) for shipping the product back to our warehouses. In some cases, this may be more than the value of the product itself. For this reason, we find it impossible to offer Cash on Delivery.
We follow maximum transparency in showing you actual delivery dates at a product level. The exact delivery dates are visible on each product page, cart page, checkout page, as well as your order confirmation emails. Once your order is shipped, regular shipping updates are provided via SMS.
We supply products only. We're an ecommerce company and our focus is on importing, distributing, manufacturing, and supplying a wide range of technical isolation & acoustic products across India. For installation you can engage local contractors / carpenters. Please contact us if you need specific information on installing any product in our catalog.
We accept returns upto 30 days from the date of receipt of product. If you need to return a product, just contact your sales representative and we will arrange a reverse pickup via Fedex. Your refund will be processed within 3 days after we get it back. We charge a 15% fee for restocking the product so this is subtracted from your refund. This is waived off if you have not removed a product from it's original packing and are returning it unused.
Your order could be in several spots... our warehouse, our custom-shop manufacturing units, anticipating dispatch, with the courier on its way, or conveyed. The principal thing to check is have you had your dispatch email? If yes, at that point it's en route. You can track your order by clicking your tracking link from that email. In the event that you haven't got your dispatch email within a week of placing your order, please do contact us.

Should the product no longer be available, we reserve the right to exchange this with a product of similar performance and value. Due to different dye lots, Aural Exchange cannot guarantee exact colour match. This Warranty shall solely extend to the original owner and is limited to manufacturing defects and excludes damage due to improper installation, freight handling, wear and tear, abuse, misuse, misapplication, colour fading or deterioration due to prolonged exposure to ultra violet light, smoke, humidity, water exposure, or other environmental factors. It is understood that the use and suitability of the product is entirely the responsibility of the buyer or specifying engineer and as such, these parties agree to hold Aural Exchange, or its associated company, and/or officers, harmless from any responsibility whatsoever other than what is clearly outlined in this warranty.
This warranty is void if the product is found to have been tampered with or misused by the purchaser, and shall not apply if the product has been physically damaged intentionally or due to accident and/or neglect, including burns, cuts, water damage, fungus, mold, stains, or is otherwise abnormally soiled or unsanitary. Any problems that are caused by abuse, misuse, or weather-related destruction are not covered. Products designed to customer supplied specifications and/or using or including a) customer supplied materials or b) non-standard production techniques or materials are not covered. Also, consequential and incidental damages are not recoverable under this warranty. Additionally, the products listed below are not covered under this warranty: 1. Accessories & Enhancements 2. Installation Materials 3. Product Samples To minimise colour-fading of acoustic foam products due to exposure to oxygen and ultra violate light, carbon is employed during the colouring process. This does not guarantee the colour fastness of the foam component and you should expect the appearance to change over time. Colour fastness is not covered under the Warranty. This warranty does not cover damage to furniture or equipment caused by contact with or destabilization of the foam components or adhesives and hardware used for installation. Care should be taken when placing the product on finished wood surfaces or other surfaces to ensure there will not be a chemical interaction between the surface finish and the foam component.
