If you're on a budget and need wireless earbuds for exercise or travel, the Jlab Go Air Sport with its sweat and dust resistance, and decent battery life would be suitable. However, if sound quality is important and you don't mind wires, the Sennheiser CX300S, which is often somewhat more expensive, offers better sound for music and video. Neither are ideal for calls or gaming, and while Jlab has a microphone with very good quality, Sennheiser's microphone quality is poor. Additionally, the Jlab earbuds are good for exercise due to their secure fit with ear hooks, whereas the Sennheisers may not be as stable. Give Feedback

Tim Gideon | April 2022
"If you want seriously bass-forward earphones for the gym, you'll be hard-pressed to find a pair more affordable than the JLab Go Air Sport. We like their long battery life and solid water-resistance rating, though we aren’t fans of their finicky on-ear controls and the case’s hardwired charging cable."

"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."
