What to check in a audio listing

Ear pads / cushions
Manufacturers sell model-specific replacement cushion kits (e.g. Bose), so worn pads can be replaced but must match the model. Ask for close-up photos of both ear pads and the headband.

Battery (wireless products)
Apple documents battery service for AirPods and Samsung/Apple document battery diagnostics; wireless audio batteries degrade and service terms are model- and warranty-specific (see page). Ask: 'How many hours does it last per charge now?'
Source: Apple Support
Left/right channel balance
Apple lists left/right volume difference causes for AirPods (debris on speaker mesh, charge state); Microsoft documents testing a second device to rule out hardware failure when one channel is silent. Ask: 'Do both sides play at equal volume? Any crackle on either side?'

110/220 V voltage selector
Yamaha's manual says the rear voltage selector must be set for local voltage before plugging in; improper setting may damage the unit and create a fire hazard. Ask for a photo of the rear label and voltage selector.

Tubes / valves and bias
Marshall states its DSL20 is cathode-biased so power valves need no biasing when replaced; Vox's manual says tubes can break from impact and need repair. Replacement requirements depend on the model's manual. Ask: 'When were the tubes last replaced? Which type?'

Used, Open Box or Refurbished?

Used
Open Box (New other)
eBay Refurbished – Certified
eBay Refurbished – Excellent
eBay Refurbished – Very Good
eBay Refurbished – Good
Seller refurbished
For parts or not working

eBay uses defined condition labels, and they are not interchangeable. An ordinary “Open Box” (listed by eBay as “New other”) is not a “Certified” anything; a seller’s own repair is not an eBay Refurbished item. Check the condition value and any warranty on the listing itself.
