Headphones and earbuds · Sennheiser
Owners keep the HDB 630 for how it sounds: rich, accurate audio across every kind of music, good enough that many accept weaker noise cancelling as the price of it.
Sound quality is the reason people buy these and the reason they keep them. Owners describe it as far ahead of other Bluetooth headphones, including the Sony and Bose rivals, and better than the wireless competition at any price they have tried.
The noise cancelling falls short. Owners rate it well below Sony's, and at least one has had it flip on and off by itself during normal use without touching the headset.
Pick up to three. You get a page with just those, side by side, on the subjects owners raised.
Once the first week is over, the sound is what stays. Owners who came from Sony or Bowers & Wilkins say the HDB 630 pulls ahead on audio and stays there, and the ones who use it daily are still convinced by it. The dongle gets real use: hi-res mode for music, low latency mode for gaming on a PC, plus USB-C and aux when wired is easier.
The parametric EQ divides people. Some tune it to taste and call it a selling point; others tried it, tried other owners' presets, and went back to the stock tuning, which they think is the best of the lot. One owner wants to type exact values in rather than drag sliders. Comfort is mostly fine, but one owner sold the pair because it did not sit well on them, and a few say the app and the price are harder to live with than the headphones.
The core, the sound, holds up. Owners who have lived with it as a daily driver still put it ahead of what they owned before. The one recurring fault is the noise cancelling: beyond being weaker than rivals, one owner reports it switching itself on and off repeatedly in normal use. Another judges the build cheaper than the Sony it replaced.
Long-term accounts are thin. Most owners here are weeks or a few months in, and nobody yet reports a failure that needed a return or a repair. Whether the ANC glitch is a firmware fix or a lasting fault is not settled in what owners have said so far.
Nothing with a clear majority yet. Owners who raised these subjects were split, or too few to judge.
Nothing has a clear majority against it yet. Counted from the owners who raised each subject, not from everyone. A subject is judged once at least 4 owners raise it.
