If you prefer earbuds for activities like exercise or travel and appreciate features like active noise cancelling and wireless convenience, then Soundcore Life P3 would be a better choice. However, if sound quality, a wired connection for zero latency, and a more immersive music experience are your priorities and you don't mind spending a little less, then the Sennheiser CX300S would suit you better. Keep in mind, the Soundcore Life P3 also offers better build quality, an integrated mic for calls, and app customization, which are not available with the Sennheiser CX300S. Give Feedback

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."

"Anker continues its trend of stealth releases, recently dropping the Soundcore Life P3 out of nowhere. This product essentially replaces the disappointing Life A2 NC as the brand’s flagship ANC model under $100. It comes with bassy audio and enough features to give even the best noise-cancelling earbuds pause."
