With HD recording now available on iPhone 4, you can even use it for recording those 15 minutes of fame Youtube videos. While the video is crisp, the sound capture may not be as great. Here’s another accessory for the iPhone 3GS, 4 and 4S called the iPhone Boom Mic where it’s a compact mic that lets you take clearer and crispier sound recordings. It attaches to the iPhone’s headphone jack and it has 2 directional settings for both near and far recording. It runs on a single AAA battery.
The iPhone Boom Mic will work with any voice or video recording apps but since I’ve not tested it, no comments on the sound quality. It currently retails for $40 and can be purchased from photojojo.
