• Specially tuned analog sound and FiiO DDB amplifier, designed to reproduce classic sound signatures with a sense of 3D space.
• Professional Silicon Labs Si4831 radio processor for a stronger signal and more stable reception.
• Custom-shaped internal antenna and detachable 3.5mm telescopic antenna for increased sensitivity.
• 450mAh 10440 lithium battery, rechargeable and replaceable, for continuous use throughout the day.
