It is true that Paypal trumps the seller's No Returns with its Refund policy.
But No Returns is not the same as No Refund.
For example, a seller may be clearing an estate, and may never want to see a low value item again, paid or not. It could happen. Or an item with low procurement cost may be worth writing off if there is a complaint.
You are allowed to charge a reasonable Restocking fee. Retail stores often have a 15% to 25% restocking fee on returns to cover their costs (opened packages, lost bolts, etc.)
Your unhappy buyer is normally required to pay for return postage in a Paypal /eBay dispute. And if he is sensible, he will use the more expensive services that have Confirmation of Delivery.
The seller is not usually required to supply a return shipping label. Sometimes eBay will do this.
These have a chilling effect on buyer's remorse.
But since the 19h century, and Timothy Eaton's 'Satisfaction Guaranteed or your money refunded', consumers have been allowed to return unsatisfactory goods.
Returns are a cost of doing business. Build those costs into your pricing, just like Timothy did.
Better to address the majority of your customers, who will be happy with your products and your pricing.
Drop the discouraging 'no returns/no refunds' and any rants attached about bad buyers. That only discourages the good customer and makes you look difficult to deal with.
Don't go on and on and on about your terms of sale.
Ship within 24 hours (business days obviously).
Don't tell customers that tracking is not available.
Don't give customers a choice of shipping method. But if you choose an untracked service, don't use it for anything but cheap and easily replaced items.
Use the 14 day refund option on the Sell Your Item form, and get a tiny boost in Search.
I notice that all your negs and neutrals are for the same generic earbuds. It looks like you have decided to get out of that market since the only ones on offer are a five pack. Good thinking. If a product is bad, just don't sell it. Sometimes, junking or donating a bad buy is the most profitable move a seller can make.
