To decide between the Bowers and Wilkins Pi5 S2 and the Koss Porta Pro, consider how you'll be using them. The Pi5 S2 are wireless earbuds with active noise cancellation, offering a more isolated listening experience suitable for noisy environments or travel. They'll provide modern features like Bluetooth connectivity and a compact form for convenience. On the other hand, the Koss Porta Pro are wired on-ear headphones known for their classic design and strong audio performance at a lower price point. They lack noise cancellation and wireless capabilities but are often praised for comfort and their unique retro aesthetic. If portability and modern features like noise cancellation are priorities, choose the Pi5 S2. For a budget-friendly option with reliable sound quality and you don't mind wires, go for the Porta Pro.

"Bowers and Wilkins isn’t looking to make an obscure, premium wireless bud catered specifically towards audiophiles. Instead, it seems apparent that they’re going for the crown: a cool and popular look, an easy and comfortable fit, and an engaging stage with a great balance that is perfectly suited for mainstream listeners and audiophiles alike."

"It’s clear to see why these have been such a popular choice amongst listeners for nearly four decades. It’s a charming pair of headphones that delivers a truly enjoyable listening experience and one that I think punches well above its weight."
