Hi internet👋and thanks for the review Mark! If anyone has questions about HDB 630 or, well, anything, let us know below the notes👇<br><br>✅ HDB 630 is not actually a successor to MOMENTUM 4. Although there is some shared DNA in the design language, they are meant for different listeners (audiophile vs enthusiast)<br>✅ BTD 700 = B.lue T.ooth D.ongle and 700 is 100 mo' better than our last version, the BTD 600. It is a type C connector first, but also adds Auracast capability<br>✅ The HDB 630 has some added space for a new magnet damper, the revised back volume, and all-new acoustic mesh we used for Hi-Res certification; in total (both ears) the thickness difference is around 7m<br>✅ In the Smart Control Plus App, you can set ANC to on or off, so that when you double tap to access it, it goes to 100%<br>✅ You can now share your PEQ settings in the latest Smart Control App update (QR code or link)<br>✅ Want entirely uncompressed audio from the source? If using a smart device with a USB port, you can use a USB-C cable to pipe directly to your HDB 630, bypassing Bluetooth altogether<br>✅ You can make an HDB 630 sound like a MOMENTUM 4 if you want to, but not as easy when it comes to making a MOMENTUM 4 sound like an HDB 630 due to the 3rd bullet point above<br>✅ If connected to your PC via USB, you can almost double the mic bandwidth for more natural voice pickup in your audio settings<br>✅ Although not covered here, the HDB 630 also has a Crossfeed, a first in this category and inspired by the legendary HE 1. It is awesome for classic, hard-panned recordings<br><br>Cheers!

You can buy the dongle separately and use it with the Momentum 4.

PX8 S2 + BTD 700 is the way.

technicality wise, the hdb630 are more capable headphones than the px8. if you're used to more consumer focused sound signatures like other bluetooth headsets, the px8 might sound better to your ears. however, they have some midbass bloat and a weird treble peak that the hdb630 lacks, and if you're more accustomed to reference gear, the 630 will sound quite a bit better.

Completely agree with the case thing! I have XM5’s that’s a similar case. It’s big… the 1 time I left my case at home and chucked them in my bag to save a little space… broken 🤦♂️

Of all the headphones I’ve tried over the years (Bose QC series, Sony XM, Momentum 4, Sonos, Apple, B&W), the PX7S3 had the best audio quality. I could hear things I never noticed before 😁<br>I’m tempted to try these HDB 630 ones if they ever go on sale

Failed to mention the dongle actually works better with the px8 s2 as they have aptx lossless rather than just aptx adaptive.
