Sennheiser caused quite a stir with the announcement of its HDB 630 headphones in late 2025. Promising Active Noise Cancellation, 60-hour battery life and all the fine-tuning app features people loved in the popular Momentum 4 headphones, these new cans were clearly gunning to be top of the pile in consumer headphones.
The trick to offering superlative sound quality comes from an included USB-C dongle, which allows the headphones to deliver aptX, aptX HD, and aptX Adaptive audio codecs, as well as up to 24-bit/96kHz resolution. Essentially, wired quality from a wireless set of headphones. Impressive stuff!
