If you're on a budget, consider the Audio Technica ATH M20X; they're considerably cheaper and provide very good sound quality. However, they are wired over-ear headphones with a long non-detachable cable, less comfortable for long periods, and not suitable for exercise or travel due to their size. Conversely, the Sennheiser Momentum True Wireless 4 are premium-priced earbuds offering excellent sound and mic quality, with the convenience of being wireless, great for calls and meetings, gaming, TV, and exercising. They also feature active noise cancelling for quieter environments and are optimized for both Android and Apple devices. Choose the Sennheisers if you value versatility and portability, with the added benefit of the latest sound technology, and don't mind the higher cost. Give Feedback

Soundguys
Jasper Lastoria | September 2023
"Audio-Technica positively defies what you can expect for around $50. Ultimately, Audio-Technica did not design the ATH-M20x to go on the subway with you. It’s for the budget-conscious, do-it-yourself producer, podcaster, or studio that needs to buy tracking cans in bulk. If you don’t need the most deluxe, comfortable headphones, maybe you’ll like the ATH-M20x for its spartan functionality. The headphones are aimed at giving you the minimum requirements without it feeling like a sacrifice."

"It’s fair to say our brief time with the Sennheiser Momentum True Wireless 4 was a generally positive one. Comfort levels seem similar to what we have experienced before and the general flavour of sound was to our liking although we need to get a pair in to test and put up against the big rivals at the money from Bose and Sony. It could be an interesting contest."
