From Thinksound, a small company that’s built its name on clear, detailed audio and a commitment to sustainability, the ts02 in-ear headphones deliver admirably on both fronts. Everything from the PVC-free cable to the packaging, which uses recycled materials, is designed to reduce their environmental impact. The handcrafted wood housing is made from renewable sources, and produces a warm, balanced sound and a soundstage with remarkable width and depth. Digital Trends praises their compatibility with virtually all genres, and one Stereophile reviewer calls them “among the most enjoyable in-ear models” and “easy to love.”
