The Bose for instance, uses
actual tactile buttons to control playback, call management, track navigation, and volume, while the B&O Play cleverly divides controls between the two earpieces — tapping the left ear, for instance, will skip a track backward, while tapping the right will skip forward.
The SmartBoy is compatible with
actual NTSC / PAL Game Boy and Game Boy Color cartridges, while sporting a classic - style
tactile button set, making the SmartBoy look and feel like a real handheld gaming console.
