The iHold iPhone tripod mount allows you to securely mount your iPhone to standard tripod with the use of a simple 1/4-20 nut (not included). This tripod mounting system allows you to set up for portrait or landscape shooting. The built-in headphone pass-thru lets you use your compatible headphones as a cable release. Every photographer needs to have one of these in their pocket. The wide base allows you to even shoot in landscape mode when you forget your tripod.
