Zoom H1 Ultra-Portable Digital Audio Recorder Along with Samson Stereo Headphone and Deluxe accessory bundle. The handy H1 audio recorder is just the right size for inconspicuous use without compromising on the quality of recordings. Like all Zoom recorders, the H1's onboard microphones are configured in an X/Y pattern, for stunning stereo imaging. Because both mics are arranged on the same axis, they are equidistant from the sound source for perfect localization and no phase shifting. The H1 records on microSD or microSDHC memory cards with a capacity up to 32 GB. This kit contains a 16GB micro SD card that allows over 25 hours of recording time at 16-bit/44.1 kHz. The H1 uses a single AA battery for up to 10 hours of continues use. The four AA batteries included provide you with up to 40 hours of the ultimate recording experience! Our accessory bundle includes: Samson closed back audio headphones, 16GB microSD card, 4 AA batteries, an auxiliary cable, and a Handgrip table tripod to mount your recorder.
