At the Paris Audio Video Show (PAVS) 2025, Sennheiser displayed three new headphones designed to meet the needs of a wide range of users, without sacrificing the high acoustic standards for which the brand is renowned. The Sennheiser HD 550, an open-back wired model, is aimed at music lovers looking for natural sound at a contained price. The Sennheiser HDB 630 closed-back wireless headphones, on the other hand, rely on high-resolution Bluetooth to appeal to music lovers and gamers. Finally, visitors were able to listen to the exceptional Sennheiser HE-1 headphone + amplifier system in a custom-built auditorium, offering a unique sound experience.
HD 550: an accessible audiophile listening experience
The Sennheiser HD 550 headphones are an affordable solution for those wishing to discover high-fidelity sound. Its open architecture offers an airy, natural soundstage, with a balanced rendering suitable for all musical styles. These headphones offer the German brand’s signature comfort and neutrality. Their design makes them ideal for home use in a quiet environment, especially for long listening sessions.
HDB 630: high wireless resolution and minimal latency
The Sennheiser HDB 630 take a different approach: wireless and closed-back, they’re optimized for portable and multimedia use. They support aptX HD and aptX Adaptive codecs, enabling a lossless, high-definition audio reproduction. Coupled with the Auracast-compatible Bluetooth BTD 700 (version 5.4) adapter, they guarantee smooth transmission with ultra-low latency.
This responsiveness makes them equally suited to high-quality music, games and videos, where audio/visual synchronization is essential. The HDB 630 are designed for users looking for performance without constraints.
HE-1 system, the ultimate experience at €89,000
At the back of the Sennheiser booth, a listening room dedicated to the Sennheiser HE-1 headphone system was phenomenally successful. This entirely handcrafted system, built in Ireland by a single person from start to finish, impressed with its exceptional components, including a marble slab. The open-back headphones feature electrostatic technology and are powered by a dedicated tube amplifier.
Summary
At PAVS 2025, Sennheiser presented two headphones with complementary approaches: the open-back wired HD 550, designed for audiophile listening at home, and the closed-back wireless HDB 630, designed for a high-definition reproduction in complete freedom. With these two models, the brand offers coherent solutions for different user profiles, always with the same priority: sound quality.
