Adorama offers the PreSonus Ceres C4.5BT 4.5" Studio Monitor Speakers bundled with the FiiO E12 Mont Blanc Headphone Amplifier and Audio-Technica ATH-M50x Headphones in Black or White for $319 with free shipping. That's $179 under the lowest total price we could find for these items purchased separately elsewhere. The 25-watt speakers feature Bluetooth, EQ, a subwoofer out, 1" silk-dome tweeter, 4.5" low frequency transducer, and frequency response of 70Hz to 20kHz. The amplifier features a 10Hz to 100kHz frequency response, bass boost, and charging indicator. The headphones feature 45mm drivers, 90° swivel earcups, and a frequency response of 15Hz to 28kHz.

Don't want the amplifier? As we mentioned two days ago, Adorama also offers the speakers bundled with just the headphones for $259.99 with free shipping.
