Superb battery life & plenty of storage - Get 10 hours of real playback time from a single charge + 8Gb of storage is enough for up to 2,000 of your favorite songs. Universal compatibility - Uploading music to your SYRYN is drag & drop simple. SYRYN supports all popular formats, including MP3, AAC, and WMA files. (Protected iTunes AAC files purchased before April 2009 are protected and not playable due to DRM). Connects seamlessly to Mac & PC. 100% Waterproof (IPX8) - The SYRYN is built for swimmers and protected by a 1-year warranty against manufacturer defects! It is fully submersible and can withstand sustained pressure up to 10 feet below the surface. Timeless Design and Functionality - Not everyone wants another complicated gizmo or tethered smartwatch. The SYRYN draws from the compact form and function of players' past, without tying you to a smart phone like other compact devices today. Easy to Use Shuffle Mode - Three large, tactile buttons enable you to easily operate the SYRYN mid stroke. Engage the onboard shuffle feature while you swim to instantly refresh your favorite playlists on the fly. Stay Active & Be Safe - We are ecstatic that pools have begun to reopen around the country. Swimming with music is a great way to shake off the quarantine blues!.
