HTC Smart & Tangle-Free Headphones
Most smartphones come with low-quality headphones in the box, so you might want to look at something a bit better. Beats headphones can be expensive, so HTC's own Smart Wired Earbuds are a good choice. The flat cable won't tangle, and we hear the sound quality is quite excellent when you need headphones over the front facing built-in speakers.
