Top-notch on-ear headphone
While it's fairly pricey at $289, the German-made Beyerdynamic T 51 p is one of the best on-ear headphones available, offering excellent sound and a comfortable fit.
Not quite epic, but quite decent
The JLab Epics ($50) may look a little cheap, but they offer a comfortable, secure fit, and sound richer than their design would indicate.
Cost-effective Apple EarPod replacement
While the $12 ErgoFit RP-TCM125 earphones don't measure up sound-wise to the cheaper RP-HJE120, they sound respectable for the budget price tag and include a one-button inline/remote microphone.
These sound good with everything
The Brainwavz HM5s sound great, are very comfortable, and are able to compete with professional headphones for an affordable price.
Small and swanky on-ear headphones
The $200 Harman Kardon Soho-I headphones are appealing if you're looking for a compact on-ear model, but they do have a few shortcomings.
