For some, the thought of anything going inside the ear causes all sorts of heebie geebies. But the Thinksound ms01 in-ear monitor, which features an acoustically enhanced, 8mm high-definition driver, just might change your thinking. Priced at $100, the Thinksound ms01 Monitor Series was designed in part with Grammy-winning musicians who produced a headphone that features advanced studio acoustics, a lightweight design, smaller speaker diameter for better ergonomics, and passive noise cancellation technology. You won’t have to worry about frustrating cable tangles with the tangle-free Thinksound PVC-Free cables, and the hand crafted, durable wood housing makes for more clear, concise sound.
