If excellent noise isolation and comfort are important to you, especially for air travel or office use, and you want built-in controls and the option for wireless connectivity, the Bose 700 headphones are the better choice despite their higher price. However, if you're looking for a more affordable, portable option with good sound quality for casual listening and you don't require features such as an integrated microphone or active noise cancelling, the Sennheiser CX300S earbuds will suffice. Keep in mind that the Sennheisers do not have wireless capabilities and lack some of the premium features like app customization available in the Bose 700. Give Feedback

Sound Guys
Adam Molina | June 2023
"Bose took active noise canceling and made it mainstream but eventually, the market caught up. Well, it seems like Bose was listening, because the Noise Canceling Headphones 700 is a complete redesign of its iconic product. The Bose Noise Cancelling Headphones 700 have a new design, improved sound quality, a touch-sensitive gesture pad for playback controls, and even USB-C charging."

"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."
