Arriva, a small company out of Colorado, makes funky-looking sports earphones that are designed to stay on your head no matter what. The Leo is the company's Bluetooth wireless model and it comes in additional colors (green, teal, and gray).
Creative was selling its excellent Aurvana Live headphones for $55, but they became so popular Creative couldn't keep them in stock. Now they're back up to their list price of $99.99, but hopefully we'll see discounts in the future.
A few years back Grado tweaked its $99 SR80 made-in-Brooklyn headphones, adding an "i" to the end of their name without actually adding it to the product itself. We still like the older SR80, which remains on the market, but recommend going for the slightly upgraded SR80i.
Klipsch Image S4 line has long been a CNET favorite in the in-ear category. The original S4 has dipped below the $50 mark while S4i, which has a microphone and in-line remote, can be had for about $10 more. In 2012, Klipsch released the newer and updated Image S4i II, which features a sturdier flat-cord design and costs $89. And you can also pick up the Image S4i Rugged ($99), an "all-weather" sports model. While the designs are each slightly different, they all sound the same.
The Monster iSport Intensity shares some similarities with the Bose SEI2i sports headphones, but they cost about $50 less. You can also get a good deal on the yellow Livestrong version of Monster's true in-ear model, the iSport Immersion -- it costs around $50 -- but that model will eventually be discontinued.
We initially had the $75 Noontec Zoro on the list, calling it a "bargain audiophile headphone" thanks to its clear, balanced sound. The standard Zoro is still available, but Noontec has more recently released the Zoro HD, which looks identical but offers better sound. It lists for $149.95 but can be had online for $99.95.
The Philips O'Neill The Stretch headphones may not have great sound but they're well designed, very comfortable, and cost less than $50. They also come in white, and there's a step-up model, the Stretch Headband Headset SHO9567BK/28 (or SHO9567WT/28), that features an inline microphone for $10 more.
The Remix remote was released back in 2010, but it's come down in price and is one of the better earphone deals out there (and it features an Apple-friendly inline remote with microphone). Like all V-Moda earphones, it delivers a lot of bass.
