Want to impress that cute hippie chick you met at the coffee shop? Show her you can hug a few trees with the best of them by playing her the latest Mumford & Sons through eco-conscious Pulpop speakers.

Yep. The "go green" craze has finally reached your entertainment center. Renouncing wasteful plastic and metal, the Balance Wu Pulpop is a USB rechargeable MP3 speaker made entirely of recycled paper pulp. (Now you don't have to feel guilty for tossing out all those back issues of Maxim.)

Wayfair

Looking like that protective packaging you find in a shipping box, sound is amplified by vibrating inside the foot-tall hollow ring. So it's not only eco-friendly, it's sciency. Maybe you should invite the hot lab tech from your doctor's office over too.
