and better suited if you prefer over-ear headphones, require a wired connection, and prioritize sound quality for music and TV. However, they lack the convenience of wireless connectivity, have poor mic quality for calls, and are not optimal for exercise or travel due to their size and lack of noise isolation. In contrast, the Sennheiser Momentum Sport is more expensive but offers high-end features: wireless functionality with AptX Adaptive for low latency, excellent build quality with better durability, active noise cancelling, optimized controls for both Android and Apple devices, and additional health tracking features. They are versatile for music, calls, gaming, travel, and exercise, with sweat and dust resistance, but they may be less comfortable during long listening sessions due to their in-ear form factor.

"If you were to pick one headset to fill all of your needs, the ATH-M40x is a great buy with its sub-$100 price tag, pleasant sound quality, and accessories.

Amelia Schwanke | January 2024
"We hadn't been expecting a new pair of dedicated sports buds but the surprise was nonetheless exciting. I got to try out the new buds at CES 2024 and while they have stayed true to delivering that "signature" Sennheiser sound, with a wide soundstage and strong sense of detail, it’s the extra wearable tech inside them that stands out to me against the best workout headphones."
