Transcend is the smallest, lightest (Less than a pound), most portable and practical sleep apnea therapy system available. It is perfect for travel and great for home too! Worn on the head, Transcend is quiet and vibration-free. The short hose and compact interface help prevent seal leaks and provide unlimited mobility. With Transcend, you’re free to roll over in bed or even get up and walk around - when using the optional battery – without breaking the mask seal, disconnecting a hose, or sacrificing therapy.
