Top critical review
Great sounding headphone, but with quite the few drawbacks concerning use when exercising.
6 July 2018
Pros: Good sound quality, a real pleasurable and warm sound which is what you want when working out.
Better than my Sony WH-1000 wireless headphones in terms of their connection to my phone over bluetooth.
Very comfortable fit in the ear - I'm quite susceptible to my ear cartilage starting to ache with some on-ear/in-ear headphones, but these headphones NEVER induce this, and I've worn them for well over 400 hours since purchasing.
Cons: Not that great for exercise, which is what they're sold on.
If you get a true sweat on, one or both ears will lose all their bass.
They stick out far too much from your ear, so in winter they're pretty much impossible to wear under a winter cycling hat, or a beanie/hoody when running or cycling in the cold.
The chord between the ear piece is a bit stiff, and twists weirdly so is never really truly comfortable at the back of the neck (clipped or unclipped).
20 months in, the plastic that covers the right ear piece has half come away and the power button has come loose from underneath this cover. Bose are repairing or replacing under warranty (so list this customer service as a massive PRO!!!).
None of these have made me annoyed enough to replace the headphones - but if they ever did need replacing, I wouldn't purchase again.
