Another good deal here – didn’t look like anybody had posted it yet, so wanted to share.

Use coupon WNUZ3SWO to get the price down to $14.70. Pretty good price for a product with a good number of positive reviews. I hadn’t heard of the brand before, but it seems like they’ve been around for a long time to get this many reviews and this many questions and answers.
Fits basically every phone (including a few notes of it fitting even with a bulky Otterbox on it) and has an earphone port that I don’ think most of these headsets have. Not sure how you can lose for under $15.
