Thought of and designed while traveling through the rugged terrain of the African continent, the Tembo Trunks collapsible silicone earbud cones are the perfect solution to sharing your iPod's music without having to carry around bulky speakers. By using simple horn acoustics, the Tembo Trunks amplifies the sound from your iPod's earbuds to 80dB of clarity enhanced stereo sound. This simple, yet brilliant, design is ideal for sharing music in a casual setting. While they are not designed for party settings or anywhere you would like to listen to music to loudly, the Tembo Trunks are perfect for traveling, camping, enjoying a day at the beach, in your bedroom, hotel room, office, or anywhere else where you don't want to where earphones but still would like to enjoy some tunes. Tembo Trunks do not require any batteries nor do they require a power cord to work. All you need is an iPod or iPhone and the white earbuds that come with them. Traditional speakers consist of potentially damaging metals, toxins, plastics, glues, and batteries that can be considered environmental hazards if not manufactured or recycled properly and responsibly. Made from 100% non oil based, high-grade silicone rubber (which the manufacturer agrees that this may not be the greenest product ever) the Tembo Trunks require no assembly, are designed to last and could potentially be considered a better alternative to traditional speakers. You never have to worry about blowing out your Tembo Trunks and have to purchase expensive replacements. Please Note: This product was specifically designed and intended for use with Apple® ear buds. The Tembo Trunks come in a multitude of colors to match the personality of their user. They come in White, Grey, Blue, and Ruby Red. Keep your headphone cords neat and tidy with the addition of the Tembo Trunks Headphone Cord and Cable Wrap Management System, available in White or Black (each sold separately).
