Upgrade your listening setup with NewFantasia’s replacement audio cable, engineered to pair with popular Sennheiser models (HD650, HD600, HD580, HD58X) and Massdrop HD6XX. At 150 cm (4.9 ft), the cable gives you room to sit back, move freely, and enjoy a relaxed, spacious listening experience whether you’re at a desk or on the couch.
