Sennheiser hasn’t debuted a premium set of wireless headphones since the Momentum 4 arrived in 2022. Sure, there were two sets of Accentum cans, but those offer more mid-range performance in the $180-$250 range. Instead of a Momentum 5 for its latest release, the company has revealed the HDB 630: a $500 set of wireless noise-canceling headphones that offer lossless listening via wired connection.
If you’re thinking the HDB 630 looks an awful lot like the Momentum 4, you’re correct. Sennheiser says this new model “inherited” the chassis from those 2022 headphones, but there’s a new acoustic system inside for “focused listening.” That setup includes 42mm dynamic drivers what were “designed for purity, not hype.” As such, the company promises you’ll hear “the vibe that left the mastering studio” thanks to careful attention to the midrange, vocals and overall dynamics.
Those drivers are supported by a high-resolution digital audio engine that works for both wired and wireless listening. Via either the USB-C or 3.5mm ports, you can expect to hear tunes in up to 24-bit/96kHz resolution. The HDB 630 also comes with a USB-C transmitter dongle for phones, tablets and other devices so that you can harness higher-quality listening with aptX Adaptive — even if your gadgets don’t support it natively. “With only an estimated 16 percent of smartphone hardware supporting native wireless high-res sound, the included dongle brings this capability to 80 percent of smartphone models in an instant through their USB Type-C port,” Sennheiser explained in a press release.
There are several audio features available on the HDB 630 for an “audiophile” experience. First, Sennheiser employs the Crossfade feature from its HE 1 headphones that blends the left and right channels to make it seem like you’re listening to speakers. There’s also a new Parametric Equalizer for more granular EQ control, complete with bandwidth, filter and A/B settings. The company says any settings tweaks are then applied to the HDB 630’s “advanced processing system” so listeners determine the tuning rather than the content or app providing it. Lastly, users will soon have the ability to share presets via QR code.
Another item Sennheiser retained from the Momentum 4 is long battery life. Like that model, the HDB 630 will last up to 60 hours with ANC enabled, so you won’t be reaching for a charging cable often. What’s more, a 10-minuted top up will give you seven hours of use. And when it’s time to travel, there’s an airline adapter included in the box.
The HDB 630 is available for pre-order starting today for $499.95. Shipping is scheduled to begin October 21 from Sennhesier and other retailers.
