The HifiMan Sundara, being premium-priced, provides a high-quality audio experience with superior soundstage, immersion, and comfort making them ideal for music enthusiasts who seek the most from their listening experience; however, they lack a microphone and are not advisable for calls, gaming, or exercise. The open-back design offers natural sound but poor noise isolation, which can be a drawback for air travel or loud environments. On the other hand, the Sennheiser CX300S, which are much less expensive, offer closed-earbuds with good noise isolation and portability, making them a versatile choice for casual listening, exercise, and travel but they won't match the Sundara in sound quality.

"The HiFiMan Sundara is the set of headphones to get if you want high-end audio, but don't want to shell out a king's ransom for it. These planar magnetic headphones are comfortable, straightforward, and excellent performers."

Major HiFi
Carroll Moore | April 2019
"Sennheiser offers impressive bang for your buck when it comes to the CX 300S. Built like a tank and sounding surprisingly good for such a budget-minded earphone, the CX 300S out-classes many of its would-be competitors. Functional but beautiful, it’s the perfect in-ear listening solution for anyone who wants to hear everything and look good doing it."
