If you value wireless convenience, active noise cancelling, and features such as an integrated microphone and app controls, the JBL Live 770NC headphones are suitable, especially for air travel and commuting due to their excellent noise isolation and long battery life. However, they are bulkier and may not be as easy to carry around as earbuds. On the other hand, the Sennheiser CX300S earbuds are much less expensive and provide a simple, wired solution with good sound quality and comfort, making them a great choice for everyday casual listening and TV, but they lack wireless capabilities, active noise cancelling, and may not be as durable for activities like exercise.

Major HiFi

Carroll Moore | April 2019
"Sennheiser offers impressive bang for your buck when it comes to the CX 300S. Built like a tank and sounding surprisingly good for such a budget-minded earphone, the CX 300S out-classes many of its would-be competitors. Functional but beautiful, it’s the perfect in-ear listening solution for anyone who wants to hear everything and look good doing it."
