Ditch your no-name OTG adapter
Crutchfield Customer Review (What's this?)
Significantly more durable than my previous no-name OTG adapter. An unexpected minor upgrade in sound quality as well. The plugs have "Carbon" written on them, which is great to see such nice wire on an adapter at this price. Note that it is not very flexible cable; this is better served on a tray table than, say, wedged between you and your seat.
Pros: Much higher build quality than generic OTG; improves sound a bit
