If you value premium audio quality with noise cancellation and wireless convenience, the Bowers and Wilkins PI7 would be a great choice despite their higher price. They also have features like a built-in microphone for calls and a charging case that doubles as a wireless transmitter for other devices. Conversely, if you're looking for good sound on a budget and don't mind wires or lack of noise cancellation, the KZ ZSN Pro could meet your needs, offering significant savings. However, keep in mind that the KZ ZSN Pro lacks the advanced features and overall build quality of the PI7. Give Feedback

"The primary selling point of the Bowers & Wilkins PI7 is the charging case that can transmit audio from any analog source to the earbuds. If you have a very specific and clear need for that feature, then the Bowers & Wilkins PI7 is for you."

"Undoubtedly the focus and the star of the show, the ZSN Pro’s bass is big, bold and bangin’. The amount of gusto in the low end should satisfy anyone who likes a large lick of bass and even certified bassheads will probably get a kick out of this."
