First Apple W1 Wireless Chip Headphone: The Beats Solo3
This story originally appeared at InnerFidelity.comThe Solo3 is the first headphones to have the Apple W1 wireless chip. (Followed shortly thereafter by the Beats Powerbeats3 and the soon to come BeatsX and Apple AirPods.) In this review I'll take a close look at the features and functions of this W1 based wireless headphone, and how it differs from typical contemporary Bluetooth headphones.
The top-of-the-line model from America's leading headphone manufacturer, these are bulky, heavy, very business-like in appearance, and very, very good.
The ESP-9 is dual-powered: from the AC line, or from the input signal itself, The power supply is rather large and heavy, and appropriate in appearance to the phones. Amplifier connections are via wires with spade lugs attached, and speaker connections are made to the rear of the power supply. A front-panel switch selects speaker or headphone operation, and terminates the amplifier outputs with 10 ohms in the Phones position.
Construction is typically top-of-the-line Koss: Rugged, nicely finished, and apparently very durable, and the phones are easy to handle. (Many headphones are so loosely pivoted on their headbands that they swing into impossible positions whenever you pick them up.)
