A range of third-party sellers at eBay take up to 83% off a selection of headphones and portable speakers as part of its Portable Audio Sale. (The banner advertises up to 50% off but we found deeper discounts within.) Plus, all orders receive free shipping. Some best bets:

• Philips Flexible Earhook Headphones for $5.99 (low by $2)
• LG ND5630 Wireless Bluetooth Speaker for $69.99 (pictured, low by $68)
