Monster via eBay takes up to 60% off its refurbished headphones and earbuds, with prices starting at $9.93. Plus, all orders qualify for free shipping. That's the best percent-off discount we've seen on refurbished headphones from Monster this year. (For further comparison, we saw a coupon for 30% off its entire store, which included refurbs, in June.) A couple best bets:

• refurbished Monster NCredible NTune On-Ear Headphones in Black for $49.95
• refurbished Monster Diamond Tears Edge On-Ear Headphones in Black (pictured) for $149.93
