Enjoy a safe way to listen to your favorite music and other audio files when using the HighClass 16GB Kosher MP3 Player from Samvix. You get 16GB of built-in storage for your files, but you can expand that with an optional SD card up to 128GB in size. The HighClass offers three ways to listen to those files: stream them to an optional Bluetooth speaker or headset, plug in an optional pair of headphones, or use the built-in speaker.
