If you prioritize excellent sound quality for music and don't need wireless capability, the Audio Technica M50x could be the better choice as it's highly regarded for its sound reproduction. However, it lacks features for modern conveniences such as a microphone, wireless connectivity, and active noise cancellation. On the other hand, the Sennheiser 450BT provides a balanced performance across various use cases, including calls and meetings, gaming, and air travel, and it offers active noise cancellation, a built-in microphone, and wireless capability with a long battery life. If versatility and modern features are high on your list, and you want to save some money, the Sennheiser 450BT might suit you better. Give Feedback

Jasper Lastoria | October 2022
"Good sound is timeless. It doesn’t matter that a number of years have passed since the ATH-M50x came out because it still works well. Since this wired headset doesn’t rely on batteries or Bluetooth technology, it’s bound to outlast its wireless counterparts. The no-nonsense performance, fit, and comfort of the Audio-Technica ATH-M50x make it worth picking up."

"The Sennheiser HD 450BT is a very good pair of headphones for the price, noise canceling is good and sound quality is great—quite rare at this price point. Like any product, this headset isn’t without its faults."
