My biggest concern, that this handset might slip off the ear is now resolved immediately after the first fittings - I can headbang so and they sit still totally committed. So for my medium-sized ears fully fit for very small ears they might be too loose. Since the plugs are hard to press me for a short while uncomfortable at 'court "to the ear canal - in this case, I put it very lightly on, then hold for normal movements to fairly strong shake of the head still full enough.
Because of the pain through to hard pegs and the loss of volume by the forced wearing of loose point deduction on four star minus.
For me as a hi-fi sound quality philistines, the speaker listening to good enough.
An improvement recommendation to the manufacturer, is still something to reduce the bud and ensure better umpolstern, best with durable natural rubber without bisphenol A, plasticizers etc ..
