The verdict
Both of these exist for people who rank audio above noise cancellation, which makes the differences everywhere else decisive. The Sennheiser Momentum True Wireless 4 holds the pure-sound edge: top audio marks, the broadest hi-res menu (aptX Lossless and Adaptive on Snapdragon phones), a deep parametric EQ, and a 2-year warranty, undercut by weak call mics, trailing ANC, and a bulky housing smaller ears fight. The Technics EAH-AZ100 gives up little on sound (its magnetic-fluid driver has fans who call it the better listen) and wins nearly everywhere else: the best call quality in the entire class, true three-device multipoint, and a 10-hour battery, at a similar or lower street price. Read the Momentum True Wireless 4 vs EAH-AZ100 question literally as a music shootout and the Sennheiser edges it, especially on one of its frequent deep sales. As earbuds you live with all day, calls and laptops included, the Technics wins, and that is where our edge goes.
