These terms apply to use of this website and retail orders placed through the EIRSONA online store.
Store operator
EIRSONA is the storefront brand. The final company legal name, registered address and company registration details must be inserted here before payment processing is activated. Customer inquiries may be sent to dataqueezguid@gmail.com.
Products and information
We aim to present product colors, dimensions, materials and published attenuation information accurately. Screen colors may vary. SNR, NRR and other rating systems are not interchangeable. Product information is not medical advice and does not replace workplace risk assessment or professional safety guidance.
Prices and orders
Prices are shown in the currency displayed on the website. Shipping, taxes, duties and currency conversion may be added where applicable. An order is accepted only after payment authorization and order confirmation. We may contact the customer or cancel and refund an order if information is incomplete, a product is unavailable, a pricing error is identified or the order cannot lawfully be fulfilled.
Payment
Payments are processed by the payment method selected at checkout. Payment-card information is handled by the applicable payment provider and is not intended to be stored directly by this website.
Shipping and returns
Processing begins on the day after an order is placed. Delivery timing varies by destination and carrier. Returns must be requested before goods are sent back. See the Shipping & Returns Policy for current details.
Wholesale and samples
Wholesale pricing, samples, customization, lead time, documentation and shipping terms are governed by the written quotation or contract and are not created by a retail website order.
Website use
You may not misuse the website, attempt unauthorized access, interfere with checkout, submit false information or use website content in violation of applicable law or intellectual-property rights.
Liability and governing terms
Nothing in these terms excludes rights or liabilities that cannot legally be excluded. The final governing law, dispute forum and legal-entity details must be reviewed and inserted before commercial launch.
