If audio fidelity and noise isolation are your top priorities, the Etymotic ER4XR earbuds, with their in-ear design and balanced sound signature, would be ideal for critical listening, despite their higher price. However, if you prefer the convenience of wireless connectivity, longer battery life, and the added feature of a built-in microphone for calls, the Sennheiser 450BT headphones would cater better to your needs, especially for everyday use and commuting, at a more affordable price point. Remember, the Sennheiser's over-ear style may also be more comfortable for longer periods, while the Etymotic's deep ear insertion provides more noise isolation which could be a factor if you're sensitive to fit.

The Etymotic ER4XR has excellent build quality, while the Sennheiser 450BT has very good build quality.
"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."
"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."
