When you want the purest possible signal, you can also plug in via USB C and listen to high-resolution, lossless files. Not to mention the included audio cable, which lets you plug into any 3.5 mm jack for maximum compatibility. Powerful adaptive noise cancellation in a closed architecture quiets the world without affecting your music, while transparency mode lets you hear your surroundings when needed. The crossfeed feature is great for classic tracks with hard-panned mixes. It takes instruments concentrated on one channel and balances them out, creating a much more natural listening experience — like hearing the track on a full stereo system.\n\t\t\t\u003c\/p\u003e\n\t\t\u003c\/div\u003e\t\t\u003cdiv class=\"clearfix\"\u003e\n\t\t\t\u003cimg class=\"img-responsive\" src=\"https:\/\/hnie-assets.s3.eu-west-1.amazonaws.com\/products\/SENNHEISER\/700445\/700445_5..webp\" alt=\"\"\u003e\n\t\t\t\u003ch5\u003eParametric Equalizer: The Precision to Get Exactly what you want\u003c\/h5\u003e\n\t\t\t\u003cp\u003e\n\t\t\t\tPrevious equalizers only provided limited benefits, whereas sennheiser new parametric equalizer gives you full flexibility to adjust your sound exactly to your needs.

The HDB 630’s parametric equalizer puts you in the driver’s seat: you can set the exact frequency range you prefer, control the bandwidth to make that adjustment wide or narrow, and choose the filter type for even more precise shaping. This flexibility lets you tailor vocals to your preference, adjust brightness, or fine-tune bass — without affecting the rest of your music. It offers a level of control rarely seen in wireless headphones, perfectly complementing the audiophile tuning. Whether you’re an enthusiast chasing the ideal audio or simply exploring, full parametric control lets the HDB 630 match your personal definition of perfect sound.\n\t\t\t\u003c\/p\u003e\n\t\t\t\u003cp\u003e\n\t\t\t\tThe parametric equalizer, crossfeed and more features like your ANC settings, advanced sound quality settings and firmware updates are all available in the Smart Control Plus App.\n\t\t\t\u003c\/p\u003e\n\t\t\t\u003cdiv class=\"clearfix\"\u003e\n\t\t\t\t\u003cimg class=\"img-responsive\" src=\"https:\/\/hnie-assets.s3.eu-west-1.amazonaws.com\/products\/SENNHEISER\/700445\/700445_6..webp\" alt=\"\"\u003e\n\t\t\t\t\u003ch5\u003eStay Comfortable and Stay Connected\u003c\/h5\u003e\n\t\t\t\t\u003cp\u003e\n\t\t\t\t\tA great headphone should take even epic playlists in stride.\n\t\t\t\t\u003c\/p\u003e\n\t\t\t\t\u003cp\u003e\n\t\t\t\t\tWith up to 60 hours of battery life, you can listen to music, podcasts, or videos literally for days.
