When choosing between the Audio Technica ATH M30X and the Sennheiser HD 350BT, consider the following: if you need Bluetooth connectivity for wireless listening, the Sennheiser HD 350BT offers that functionality, while the ATH M30X does not. The Sennheisers also support AptX Low Latency, which is great for video and gaming as it reduces audio lag. However, the ATH M30X has a reputation for strong sound performance in its price range and may be somewhat less expensive. If having a built-in microphone is important to you, the HD 350BT includes it, which the ATH M30X lacks. The Sennheisers might be more suitable if you value wireless convenience and features, whereas the Audio Technicas could be the choice for a budget-conscious wired option with a strong emphasis on audio quality.

Jasper Lastoria | August 2023
"The Audio-Technica ATH-M30x is a great choice for anybody that needs a decent set of over-ear studio monitors. While the frequency response is not totally spot on, it works for basically every situation reasonably well. The sound quality and reasonably good comfort promote its candidacy as a great pick for $69 USD."

"Sennheiser nails just nearly everything about the Sennheiser HD 350BT headphones. Sound quality is excellent, and the high-quality Bluetooth codec support is a rarity at this price point. If you don’t care for high-tech features like automatic ear detection, you’ll be delighted with these portable headphones."
