Which Bluetooth codecs are supported by the HDB 630?

The HDB 630 supports SBC, AAC, aptX, aptX HD, and aptX Adaptive.

It comes with the BTD 700 to upgrade compatible USB C devices (such as your smartphone or tablet) into a hi-res aptX Adaptive transmitter.

How do I get the best sound quality with the BTD 700 Bluetooth USB C dongle?

BTD 700 can be connected to any compatible USB C device and must be paired with the headphones before use. To maximize battery runtime, hi-res (24-bit/96 kHz) is not enabled by default, so the user must activate hi-res in the Smart Control Plus App.

Does the HDB 630 come with the USB C to A Adapter provided with retail version BTD 700?

The HDB 630 is supplied with the BTD 700 USB C dongle and does not include a USB C to A adapter.

Why is aptX HD or aptX Adaptive not working?

Please check whether your source device supports both codecs.

Hi-res mode is not enabled by default in the Smart Control Plus App to optimize runtime.

Users can change this in the Smart Control Plus App’s Settings > Resolution.

How can I enjoy hi-res Bluetooth on the HDB 630 using an older iPhone model with a lightning port?

Our BTD 700 is a hi-res transmitter that works with iOS devices with a USB C connector.

For iOS devices with a lightning port, users will need a compatible USB C to Lightning adapter that supports Audio OTG.

User source MFi-certified adapters.

Audiophile tuning: Sennheiser’s in-house 42 mm transducer and refined acoustic design deliver a neutral audiophile sound with lifelike mids, stunning detail, and a wide, natural soundstage. With minimal digital processing ensuring pure fidelity true to the original recording.
Wireless or wired: Enjoy high-resolution wireless sound with support for aptX HD and aptX Adaptive, especially when paired with the included BTD 700 Bluetooth adapter. For maximum purity, connect via USB-C for lossless listening up to 24-bit/96 kHz.
Parametric EQ: Expert-level equalization lets you define frequency bands, widths, and filters to precisely shape your sound. Tailor bass, enhance vocals, or fine-tune for any genre, just like a mastering engineer.
Adaptive ANC & Transparency Mode: Powerful noise cancellation blocks distractions without degrading clarity, dynamics, or balance. Transparency Mode instantly lets in surrounding sounds when you need to stay aware.
Listen for days, not hours: A class-leading 60-hour battery keeps you going through long trips or work weeks. Just 10 minutes of fast charging adds up to 7 hours of playtime, ideal for when you’re on the move.
Customers praise the headphones’ connectivity, noting they easily connect to phones, and appreciate their battery life. The sound quality receives mixed feedback, with some finding them very good sounding while others say the audio quality with the dongle is poor. Moreover, the noise cancellation and sound customization features get mixed reviews, with some finding the noise cancellation good while others say it’s not as effective, and while some find the app wonderful to use, others find it complicated. Additionally, reliability is also mixed, with some saying it works well while others report it completely stops working.
