The 1MORE HiFi Triple Driver Over-Ear Headset helps deliver a hyper-realistic detailed sound stage with silky highs, precise mids, and deep bass. It provides Hi-Res Certified audio quality and features a graphene driver with ceramic tweeter and passive radiator. Close your eyes and you're standing in front of a stage.

The 1MORE HiFi Triple Driver Over-Ear Headset provides stunning studio quality sound thanks to three 40 mm graphene dynamic drivers, ceramic tweeters and bass reflector. This helps deliver a hyper-realistic detailed sound stage with silky highs, precise mids, and deep bass. Almost all over-ear headphones make one driver do all the work, causing distortion and loss of detail. Just like a hi-fi sound system, we loaded these headphones with a highly efficient ceramic tweeter. This means it's capable of faster response times for exquisite detail and shimmer, while a bass reflector used in boutique speakers allows for extended bass and depth, and the audiophile-grade graphene driver delivers full range definition. Close your eyes and you're standing in front of a stage.

The state-of-the-art durable aluminium alloy design features anodized aluminium alloy ear cups for lasting durability and fingerprint resistance. An adjustable stainless steel leather cushioned headband with rotating leather cushioned ear cups ensures a comfortable fit that perfectly conforms to your head and ears. The inner headband uses intelligent grooves to alleviate pressure, while the leather cushioned ear cups rotate 45 degrees to conform to your head and ears. Its closed back noise isolating ear cups naturally quiet your surroundings while keeping sound from escaping. Music feels alive when you don't feel your headphones. The ear cup housings can be rotated inward 45 degrees or completely folded for easy storage and travel. A collapsible design conveniently fits into included deluxe compact traveling case. The 1MORE HiFi Tripe Drive Over-Ear Headset is thus also perfect for travel.

Luca Bignardi, 1MORE's lead sound engineer, perfected the final tuning of the Triple Driver Over-Ears to bring a fully balanced and precise soundstage. The audiophile-grade detachable cable consists of oxygen-free copper wire with Kevlar® core and elegant braided sheath to deliver meticulous sound, durability, and freedom from tangles. The aluminium alloy sound chamber enhances acoustic response while polymer "rims" protect the outer bass reflector for extended flexibility and durability. Balance and beauty combine when everything has a purpose.
