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.
