| Customer Reviews: Average Rating:  Rating : - Top Rated in Consumer Reports Very pricey (Amazon beats Wal-Mart hands-down), but they last the longest of any battery source. Consumer's just reviewed batteries for power-hungry digital cameras and confirmed same. I use 'em in my battery-eating HeadRoom Super Bithead portable headphone amp (4-AAA) along with my iPod Classic and Shure SE-530PTT music rig, and they outlast multiple sets of Duracell copper-top and Energizer Max alkalines. I carry an extra set in my computer bag so i'm never without my tunes! LOL! + See Full Customer Review |  |
