These are exactly what you expect to get for soft cushioned, in-ear earbuds. Sound is great and doesn't disturb your sleeping partner or fellow transit travelers.
I purchased these JBL T110 In-ear sound isolating headphones so I could hard wire into my laptop for zoom calls. The fit is very comfortable with 3 sizes of soft ear pieces provided. Sound isolation was very good with the people I was talking to able to hear me with no distortion or problem. I recommend these.
These earbuds sound good considering the price, my only complaint is that they are harder to stay in your ears than other earbuds so they need constant adjustment.
Initially I was a bit disappointed with the sound quality. But I replaced the medium-sized rubber that came in it with a smaller one, and boy oh boy, the new fit made a world of difference. Very punchy and clear sound, with no distortion, amazing quality especially for the price paid.
