Alpha & Delta KS100 True Wireless Earphones

One of the principal reasons a pair of earphones sound the way they do is their driver array. Normally, you’ve got to select whichever IEM has the right one for your needs, but Alpha & Delta is bringing true optionality to the true wireless earphone space with the KS100. Available here are two entirely different driver arrays: a single dynamic-driver build for focus on power and bass, or a dual-driver system that adds a balanced armature to bring definition and detail. In either case, the KS100 is a compelling package with a Bluetooth 5.2 chip for steadfast wireless transmission, an impressive 120 total hours of use when factoring in the 2,500-milliamp hour battery case, and excellent IPX6 water resistance. This, when taken together, means that these earphones are the total package for the on-the-go audiophile. So just ask yourself this: are you a single-driver or hybrid-system listener?
