The JBL TUNE 750BTNC are only alright for mixed usage. Due to their awkwardly-sized ear cups, they aren't the most comfortable unless you have very small ears. They're also made entirely of plastic and don't feel very durable or well-built.
Very well-balanced and versatile sound profile; Good, longer-than-advertised battery life; Easy-to-use controls.
Awkwardly-sized ear cups aren't very comfortable; Mediocre noise isolation, even with ANC; Plasticky and cheap build quality.
