The PI7’s are hands down the best wireless earbuds I’ve ever heard and for $400 they better be. The sound they put out is great, the noise cancelling is good, and the ability to use them as ‘wired’ headphones via the case is a pretty innovative feature. I don’t know if they're $150-$200 better than some of the other options out there, but like with the PX5’s that I still use almost every day sound quality is king here and if that’s what you’re after this is it.
The box contents are pretty straightforward. You get the buds, charging case, a USB-C cable for charging and wired audio, and a USB-C to 3.5mm cable for wired audio. There are 3 different sizes of silicone eartips to choose from; I went with the largest of them and that formed a good seal in my ear. I do wish there were some more options at this price though; foam tips would have been appreciated. The case is small enough to fit in most pockets and is a bit bigger than my Pixel Buds case and a bit smaller than my Sony WF-1000XM3 case. The case is also lighter than I expected, but feels sturdy enough. I really like the look of the buds with the circular brushed metal caps and the white/pale gold scheme conveys the premium look well.
Getting the buds setup for me on my Pixel 4 was not as straightforward as I had hoped. These are supposed to have the Android Fast Pair feature (similar to what AirPods do on the iPhone), but I wasn’t able to get that working on my initial setup and ended up pairing in the Bluetooth menu instead. No big deal and maybe just an issue in my specific scenario, but something I noticed. Once paired I didn’t have to worry about it again. I was able to get into the settings using the same Bowers & Wilkins app I used for my PX5’s and the app is clean, if a little spartan. You have options to adjust the noise cancelling and transparency modes, manage device connections, listen to some soundscapes, update the firmware, and that’s about it. It didn’t leave me wanting for more, but I imagine some would prefer some EQ settings here. The buds support Bluetooth 5.0 and, more importantly, AptX Adaptive for hi-res audio. My Pixel 4 doesn’t support AptX Adaptive, but it is backwards compatible with AptX HD, which it does.
Getting into the sound - it’s just stupid good. Whether I was listening to standard quality stuff in YouTube Music or hi-res tracks on Amazon Music HD. I’ve never listened to earbuds that sound this good. Every song I listened to had so much detail coming through that I never really picked up with other buds. The bass is also surprisingly strong without overwhelming the rest of the audio. Everything I listened to also sounded more like it was ‘around’ me rather than being piped directly into my ears, if that makes sense. The connection for me has been solid 95% of the time, but there are some scenarios where I get a lot of interference coming in. I’m not sure what the issue is there, but it seems like popping the earbuds into the case and then reconnecting them fixes it. The noise cancelling is solid and did a good job blocking out a fan and a TV running across the room from me (the TV was still audible with nothing playing, but never when I was listening to anything). There is a transparency mode you can turn on as well if you need to let some outside noise through; it’s no worse than I’ve heard on other earbuds, but still feels a bit artificial to me.
One really unique feature of the PI7’s is the ability to use them ‘wired’ with the case. You can do this with either the USB-C or 3.5mm cables included in the box. The headphones will automatically detect that the cables have been plugged in and switch to communicating with the case. I found it worked as advertised, though using the USB-C cable to connect to my PC there is a noticeable audio-sync issue with video content. This was not as much of an issue with the 3.5mm cable for some reason, though I believe audio quality with the 3.5mm cable is slightly worse as it also has to get audio via whatever DAC is running the 3.5mm jack. Still, it’s a super unique feature that I could definitely see using in situations where Bluetooth isn’t available or I don’t want to bother pairing my buds to a new device.
Miscellaneous:
Microphone quality was okay, but a little disappointing at this price point. I don’t take a lot of phone calls, so this is a minor issue for me.
Battery life is 4 hours and the case will provide 4 additional charges (up to 20 hours total). On the low side to be sure compared to other options, but not an issue for me as I rarely wear headphones or earbuds that long.
Comfortable in my ears.
These can only be paired with one device at a time. Disappointing omission for me since I used multiple devices at the same time and the PX5’s I own support this.
I’ve read these are water/sweat resistant at IP54, but can’t find much official mention of this, so I would probably stay away from those types of activities with these.
Overall I’m really stoked on these earbuds. I have some issues, but none that break the entire experience for me (and hopefully ones that can be fixed with firmware updates). The question of whether it’s worth it to pay $400 for earbuds is one you’ll have to answer for yourself. These sound great, but I didn’t go to my other wireless earbuds and suddenly hate how they sounded, so you do need to really value that sound quality.
