If you prioritize wireless connectivity and active noise cancelling for a quiet listening experience, particularly during air travel, the Sennheiser 450BT is the suitable choice; they also have better overall build quality and microphone performance, suitable for TV and video with low latency, and come with a foldable design for portability. However, if you're on a budget and primarily need earbuds for music and portable use, the Sony MDREX15AP, while wired and lacking noise cancellation, are more affordable and offer good comfort and sound quality for their price, but they might not be the best for calls or high-durability needs.

"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."

Make It Sound Great
Pete Anthony | June 2022
"At the ultra budget $10 price-point (and we’ve seen the no-mic version go for as cheap as $7), I’d say these are a decent option if you’re looking for a passable pair of earbuds for basic use that’s as cheap as possible. I wouldn’t say they feel or sound as good as some of the ultra-budget alternatives out there – of which there are a few at this point – but some might disagree. I will say though that the cable is a little bit nicer than those of that same competition."
