Our Verdict

Sennheiser MOMENTUM 4 Wireless

Sennheiser HDB 630

In many ways, the Sennheiser HDB 630 are a more premium version of the Sennheiser MOMENTUM 4 Wireless. To be clear, the HDB 630 are not a sequel to the MOMENTUM 4, but they have remarkably similar designs and build quality. And though the chassis may be similar, the HDB 630 have a more balanced sound, better noise isolation, and a better mic. They also come with a Bluetooth dongle that adds versatility to the overall package. On the other hand, the MOMENTUM 4 are much cheaper, still sound good, and have a longer battery life. In the end, the choice between the two is primarily one of budget.
