Adorama offers the PreSonus Ceres C4.5BT 4.5" Studio Monitor Speakers bundled with the Audio-Technica ATH-M50x Headphones in Black or White for $259.99 with free shipping. That's $159 below the best price we could find for these items purchased separately elsewhere, although we saw this bundle for $5 less with rebate hassles five days ago, since expired. 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 headphones feature 45mm drivers, 90° swivel earcups, and a frequency range of 15Hz to 28kHz.
Also available is the PreSonus Ceres C3.5BT 3.5" Studio Monitor Speakers bundled with the Audio-Technica ATH-M50x Headphones in Black or White for $199.99 with free shipping. That's $9 below our mention from three weeks ago and the lowest total price we've seen. (It's a current low by $92.) These speakers feature the same specs as the above model but with a 3.5" low frequency transducer and frequency response of 80Hz to 20kHz.
