Design and Comfort

When it comes to aesthetics, both models favor understated designs, prioritizing functionality over flashy appearances. The **Sony WH-1000XM6** features a sleek, soft shape with a matte finish, weighing only **250 grams**, making them exceptionally lightweight and comfortable for extended wear. In contrast, the **Sennheiser HDB 630** tips the scales at **310 grams** and boasts a sturdier design.

Both headphones include touch-sensitive controls on the right earcup for playback management. The **HDB 630** offers a more expansive area for these controls, although it limits users to activating only the voice assistant with a dedicated button. The **WH-1000XM6** includes a button for ANC mode switching, enhancing its usability.

For wired listening, the **Sony WH-1000XM6** features a **3.5mm audio jack**, while the **HDB 630** uses a **2.5mm jack**. The latter’s USB-C port can be utilized for both charging and listening, presenting a practical advantage.

Battery Life and Features

Battery performance varies significantly between the two models. The **Sennheiser HDB 630** offers an impressive **60 hours** of playback with ANC activated, while the **Sony WH-1000XM6** provides **30 hours**. In urgent situations, a quick charge of just **10 minutes** grants **7 hours** of use for the **HDB 630**, while the **WH-1000XM6** offers **3 hours** from a **3-minute** charge.

Both models support various Bluetooth codecs, with the **Sony WH-1000XM6** utilizing **LDAC**, which is compatible with certain Android devices.
