Sennheiser M4

Owners keep the Momentum 4 for the sound, the long battery and all-day comfort at a desk, and accept noise cancelling that falls short of the best rivals in loud places.

What keeps coming up

The sound is the reason most people keep it. Owners who own far more expensive wired headphones still reach for it as a daily wireless pair, and many say a little EQ work makes it better than anything else they have used wirelessly.

What keeps coming up against it

Build quality is the clear complaint. Owners describe a cup going dead or buzzing after regular use, and say support offered troubleshooting steps rather than a replacement.

Life with it

Once the novelty passes, what stays is the sound and the battery. Owners who spend most of the day in front of a computer describe these as the pair they simply leave on, and several who sat down to compare newer headphones against them out of the box came away preferring the Momentum 4's stock tuning. The app, with its many settings, is a plus for some and a frustration for others; that theme is divided.

The adjustment most people make is around noise cancelling. Owners are split on it. Some find it quiet enough for an office and only miss stronger cancelling on long flights; others, especially those who have used Sony's equivalent, turn the volume up to cover what leaks in. A few found the fit made the difference and got a better seal by rotating the cups. Comfort is also divided: fine for many, but some owners who moved to the newer Momentum 5 say it feels lighter with less clamping force.

Reliability & repairs

The electronics and battery hold up well in most accounts, and owners with one to two years of daily use are largely still using them. Where things go wrong, it is the body of the headphones: the hinge is a clear concern, with more owners reporting problems than not, and build quality complaints centre on a driver failing on one side or a buzz appearing in a cup. When that happens, owners say Sennheiser's support pushed troubleshooting instead of a replacement, and some moved to another brand rather than fight it.

Long-term accounts here are thinner than the sound and noise cancelling discussion, and several owners in the durability thread are actually describing older Momentum models or rival headphones. Treat the hinge and one-sided failure reports as a real pattern but not a settled failure rate.
