The "Groove Buds Premium In-Ear Headphones - MP3 In-Ear earphones black - Eco Edition" are well-made, in my opinion and convincing sound quality and price / performance. As my old cell phone stereo headset was to use after only 3 months as a mono headset, had her new headphones. The accessories is extensive; the bag that came with is practical and ideal for my Samsung SGH-D900i!
