Hitting ultimate potential like a roadblock is Apple’s closed ecosystem that doesn’t allow transmission with the AptX codec. So right off the bat, if you want the best possible sound quality from the PI7, use it with an Android device that is AptX compatible. Between our Samsung S22 Ultra and the iPhone 13 Pro Max, using Apple Music, we clearly gravitated towards the Android device for critical listening due to the ability to transmit in 24-bit resolution. Whether it’s 24-bit on the Android or 16-bit on the iPhone that was making the difference, the level of engagement, clarity and overall soundstage depth was better on the S22 Ultra. The PI7 has an obvious bass boost to its tuning that emphasizes the low-end and depending on the track and recording, can get a bit much and even stressed out the dynamic driver on Be Your Man by Cub Sport. Thankfully, the PI7 redeems itself when it comes detail and resolution and it has plenty of both. Raiders March by John Williams is played back with verve and openness that makes it easy to find yourself in a swashbuckling western hunting for lost treasure. Even while you may actually just be waiting for your turn at the ATM. In typical B&W fashion, the midrange is recessed just the right amount to control the forwardness of instruments or vocals and it’s the characteristic that makes it easy to listen to them for long durations. Low level detail on acoustic music is superbly resolved and there’s a refinement to the sound that sets it apart from lesser competitors.
ANC on or off, the difference is hard to tell, especially indoors. Out on the road (or mid-air), the AirPods Max or Sony WF-1000XM4 both beat it in terms of noise suppression.
