Sound Guys
Lily Katz | March 2023
"The Bose QuietComfort Earbuds is a great do-it-all option for anyone, so long as you can afford it. This is a great alternative to the Apple AirPods Pro and Sony WF-1000XM4. You can choose the degree of noise canceling, and enjoy premium features like automatic ear-detection. These earbuds merit an IPX4 rating, making them a fine workout companion."

"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."
