## What reviewers say

**Bose Ultra Open Earbuds** — All four whitelisted outlets (SoundGuys, What Hi-Fi, TechRadar, Engadget) reviewed this exact model hands-on. All four praise the comfortable clip-on open fit that stays put during workouts and all-day wear. Three (SoundGuys, What Hi-Fi, TechRadar) explicitly flag the $299 / £299 price as high. They split sharply on sound: TechRadar and What Hi-Fi call the bass impressively full, while SoundGuys and Engadget find it subdued and the open design a genuine compromise. (4 sourced reviews.)

**Soundcore AeroFit 2** — Two whitelisted outlets reviewed the exact ~$100 Soundcore AeroFit 2 (SoundGuys, tested over a week with HEAD acoustics MDAQS measurements; Digital Trends, hands-on but no instrumented measurements). Both praise the adjustable four-position comfort and in-case wireless charging, and both flag overly sensitive touch controls and the open design's weak bass and isolation. They split sharply on overall sound quality. (2 sourced reviews.)
