If you prioritize sound quality and use your device primarily for music, the Sennheiser HD 350BT headphones offer superior sound and are more comfortable for long listening sessions. They also have the added convenience of wireless connectivity and a longer battery life, making them versatile for various activities including calls and meetings, and they are optimized for both Android and Apple devices with virtual surround capability. However, if you require the best in noise isolation for environments like air travel, or if you prefer a more portable and discreet option that is also great for exercise due to a secure in-ear fit, the Etymotic ER4XR earbuds would be the better choice despite their higher price. Keep in mind, the ER4XR are wired and have no microphone, whereas the HD 350BT offer a good mic for calls. Give Feedback

"The Etymotic ER4XRs' top qualities are the detail and definition of the midrange, rewarding the closest listening. While the soundstage is large rather than gigantic, the excellent separation and spatial precision mean you can dive deep into music just as much as when wearing a pair of full-size open-backed headphones."
"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."
