The verdict
This is the connoisseur’s matchup — two sound-first earbuds for buyers who care more about audio than ANC. The Sennheiser Momentum True Wireless 4 has a slight edge in pure sound quality and the broadest hi-res codec support (aptX Lossless and Adaptive), plus a deep parametric EQ and a 2-year warranty — but its ANC trails, its call mics are weak, and the bulky housing fits smaller ears poorly. The Technics EAH-AZ100 answers with a more complete package: nearly-as-good (some say better) natural sound via its magnetic-fluid driver, the best call quality in the entire class, true three-device multipoint, and a longer 10-hour battery — at a similar or lower street price. Choose the Sennheiser if pure sound and aptX Lossless on a Snapdragon phone are everything (and you’ll catch it on sale); choose the Technics if you want the better day-to-day all-rounder — sound plus calls, multitasking, and battery. We give the edge to the Technics.
