Lightweight, Collapsible Design

Ideal for office and studio use, the Ultrasone HFI-450 headphones feature a lightweight, folding design that makes them equally suited for listening on the go. The oval-shaped cups and soft padding keep you comfortable, while the closed-back design blocks outside noise just as well as some of the company’s pricier offerings. The 40-millimeter mylar drivers deliver a clear, powerful sound with even balance and a slightly emphasized bass. And when you’re done, the headphones collapse for easy storage in the included carrying pouch. For more info, check out this review from The Headphone List, which praises the HFI-450’s build quality, isolation, and secure fit, calling it “a very well-rounded choice.”
