Sennheiser HDB 630 Battery and Audio Issues Skip This Overpriced Headache

The Sennheiser HDB 630 wireless headphones claim to be the best in terms of sound and extended battery life, yet the early adopters are having massive battery and audio issues that prove to be a poor purchase. At an expensive price of about 500 or 42,000 in India, these ANC over-ear headphones appear expensive but fail to satisfy on the basics leaving many disappointed and empty-pocketed.
One of the worst disappointments is battery life. Maximum Sennheiser has a noise cancel duration of up to 60 hours, although actual tests prove that it only lasts 20-30 hours after a couple of weeks. According to the users, the battery wears out quickly during calls or when changing the device, and the quick-charge feature does not work as expected to provide at least 2 hours of life when the battery is charged within 10 minutes and cannot be replaced easily. What is worse, the built-in battery is riveted in place, and there is no simple way to change it. When it fails after 2-3 years as most Bluetooth devices do, then you have to pay to get it repaired or dispose the entire unit. The fact that it cannot be serviced by the user should be interpreted as additional costs and inconvenience, as opposed to cheaper headphones, where you can replace a simple battery.
Sound quality is very good initially with clear highs and fair bass but problems arise very soon. Most of them experience crackling or distortion with high volumes, and mostly in areas with lots of noise, ANC is expected to assist, and it only distorts the sound. The EQ adjustments of the app do not really help the unbalanced bass which overpowers too many songs and disappears in some. Connection outages are frequent as well, Bluetooth freezes in between walks or flights and the dongle supplied hardly helps. To audiophile users, the fact that this does not have true lossless support, and the crossfeed mode is strange, is just more disappointing and makes songs sound dull and dead in comparison to the wired versions at half the cost.
To make matters worse the build is of low quality. The glass frame is easy to scratch, and ear cushions are worn out after an hour which is uncomfortable. ANC helps in blocking noises whilst allowing in hums and echoes which destroy the peaceful listening experience. There is bad sound in calls and the voices are robotic and the background sound is leaking. All this for $500? When competitors such as Sony or Bose can be found to be more reliable and offer better features at a lower cost, this can be difficult to justify.
The social media are full of regrets by buyers that jumped the hype. One of the users commented, “Battery life is one month, sound glitches each day, utter garbage at this cost. The other one replied, “Spend your money on something better; it is a hyped sound and issues begin immediately. These headphones then scream off without a solution in terms of updates, telling any person who is smart enough to avoid spending money.
Only stick with established budgets under 200 that will last longer and are not as dramatic. The HDB 630 may perform well in the lab, but in the field, it is a costly error that will occur.
