If wireless convenience and features like sweatproof certification and active noise cancelling are important to you, the JBL Tune Buds will suit your needs, but keep in mind that they offer lower call and meeting quality. The Sennheiser CX300S, on the other hand, provide a wired connection that could offer a more stable audio experience with slightly better sound quality for music and video, but lack modern features such as an app equalizer and wireless capabilities. If you frequently use earbuds for exercise or travel, JBL's sweatproofing and noise isolation may be more beneficial, while Sennheiser offers a simple, robust build with no frills. Give Feedback

PC Mag

Tim Gideon | September 2023
"JBL’s Tune Buds stick with the company’s signature bass-heavy sound by default, but a quality in-app EQ lets you sculpt the audio to taste. These noise-cancelling true wireless earphones also mitigate environmental distractions fairly well for the price and offer good battery life. If you're specifically seeking bold, bass-tuned audio out of the box, the Tune Buds are worth a listen."

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."
