Reference Class 3-Way earphone
The K3003s have three sound tuning filters to give today’s audio connoisseur complete control. With their reference sound and true 3-way design, these high-end headphones are arguably the best in ear designs available, truly superb!
K3003i, the priciest in-ears we’ve tested, but also, by a massive margin, the best. They even put pricely full-size units to shame.
