Owner Reviews, Ratings, Comments and Criticism
I was skeptical about ordering these simply because of the low price. These were less than $2 while other sellers had them for $6~$16. But no, these work super. This boom mic works better than a $15 Zalman I bought which were in the "recommended" section of the headphones I ordered.
