The Pro4S Studio Headphone is specifically crafted for professionals who use headphones every day to create the world’s greatest music. Featuring the all-new SLX40 element, tuned for reference, the Pro4S Studio Headphone delivers an incredibly accurate and unbiased sound, perfect for any studio or creative environment. The Pro4S Studio Headphone features the natural fitting, iconic “D-profile” earcup that mimics the shape of the ear. Designed for the rigors and wear of professional use, the Pro4S Studio Headphone features an incredibly rugged mechanical design.
The aluminium earcups with memory foam cushions wrapped in soft protein leather make the headphone strong but incredibly comfortable. An all-new integrated, metal-on-metal assembly of the headphone makes the headphone extremely robust in areas where other headphones often fail. The Pro4S Studio Headphone features a detachable cord with dual-choice entry, allowing the user to choose which earcup to connect to for optimum adaptability. Once the cord is attached, the opposite side becomes an output, allowing pass-through listening or daisy chaining for extended monitoring. The Pro4S Studio Headphone folds flat into a travel case for easy portability.

    Comfortable & Ideal
    Color: 2 Pairs: Black
    As a hot sleeper, I could never wear regular socks to bed, so I thought I’d try these. They have been comfortable and ideal for my needs. They’re easy to slip on and I take them off before I get out of bed. They’ve been great and my heels look WAY better after just 3 nights. Happy with the purchase!

    Great buy for rough heels
    Color: Gray
    These work great on hubby's feet which are always so dry. Just have to be consistent. They fit great and are comfortable he says.
