Measured, not guessed: battery, noise cancelling, displays and charging from the Nodal lab.
We measured both in the same room at 75 dB of office noise. The Arcwave Studio 2 cut 38 dB, the Fenn Halo 34 dB; the Halo is 38 g lighter and the more comfortable fit for long flights.
Battery: 40 hours for the Studio 2, 32 for the Halo, both with ANC on. Lab score 9.2 and 8.7.
Every phone, laptop and watch runs the same loop: screen at 200 nits, Wi-Fi on, a mix of video, web and calls. That is why our hours are often lower than the box: they match real use.
The battery meter on every card places a product against the rest of the range.
OLED wins in a dark room: perfect blacks and the widest viewing angle. QLED wins in a bright living room and costs less per inch.
Both Lumen sets support 120 Hz gaming over HDMI 2.1.
One GaN charger with two USB-C ports charges a laptop and a phone at the same time. We measured 0 to 50 % in 28 minutes on the Novik One.
Pair it with a 240 W braided cable and you are set for every device you own.
