AcousticSheep SleepPhones SC5PM
Ultra-thin flat dynamic drivers inside a soft, machine-washable headband allow for side-sleeping without pressure, a design created by a physician as a drug-free sleep aid. The breathable, hypoallergenic Breeze fabric doubles as an eye mask and houses a sturdy 48-inch braided cord, making it a durable, travel-friendly solution. This is best for side sleepers and tinnitus sufferers who prioritize all-night comfort over audio fidelity for calls or studio monitoring.
