I'm forever on the lookout for inexpensive headphones that sound good and are comfortable to wear. As part of that quest, I purchased a pair of JVC Flats for $11.99 and took them for a spin.
I came away pleasantly surprised.
At first glance, the Flats look like a slight upgrade over a pair of headphones you might get on the plane. Under closer inspection, they're a couple notches up from that but they still look and feel like inexpensive headphones.
But they are lightweight and should offer a comfortable fit for most people. They're an on-ear model, so the earpads sit on your ear and don't entirely cover it. People with bigger ears -- and bigger heads -- may find these a little too small. But I had no problem with them.
As far as extra features go, there really aren't any. They don't come with a carrying case or have an inline remote with microphone. The headphones are all you get, and while they don't fold up, as their name implies, they do fold flat. They're designed to be slipped into a bag, but I advise you to keep them in some sort of cover or case if you want them to last a while. The glossy finish on the earpieces -- they come in multiple color options -- will get scuffed up over time and the headband doesn't seem incredibly sturdy. But to reiterate, I paid a little over $12 (with tax) for the Flats, so I wasn't expecting too much.
