Timbre iPhone Dock
Though Timbre isn’t the first passive amplifier we set our sights on, it’s small, boasts big sound, and, doesn’t eschew aesthetics (i.e. look like a horn). This genuine walnut-crafted dock sports an inner chamber that increases your iPhone’s speaker volume by up to 20 decibels, enough for casual listening, and includes one of two faceplate – white or black – to match (or contrast with) the colour of your device.
