SENNHEISER HD 660S2 WIRED OVER-EAR HEADPHONES + SONY XB100 PORTABLE WATERPROOF BLUETOOTH SPEAKER (GRAY). Sennheiser HD 660S2 Wired Over-Ear Headphones deliver an enhanced audiophile listening experience as the successor to the HD 660S with improved bass response and refined acoustic performance. Featuring an optimized steel mesh surround, improved airflow around the transducer, and lighter-weight higher-impedance aluminum voice coils, these headphones produce stronger impact and extended sub-bass while maintaining balanced and natural sound reproduction. The open-back design and soft velour earcups provide outstanding comfort for extended listening sessions, while drivers matched within ±1 dB ensure precise and intimate high-fidelity audio. Two detachable cables are included, one with a 1/4" unbalanced connection and another with a 4.4mm balanced connector, along with a 1/4" to 3.5mm adapter and carry pouch. The HD 660S2 features enhanced low-end extension that doubles sound pressure at the lowest frequencies, a comfortable ergonomic headband with breathable open-back design, and a revised coil design with 300-ohm impedance for improved magnetic force and electrical damping. Technical highlights include optimized airflow to increase low-frequency pressure, Duofol aluminum voice coils for improved detail retrieval, stronger high-frequency response above 5 kHz, a vented magnet system to minimize distortion, 38mm dynamic drivers, steel mesh baffle for natural bass response, and excellent stereo imaging.

Sony XB100 Portable Bluetooth Speaker (Gray) is designed for portable listening and outdoor use with a UV-resistant coating and IP67-rated protection against water and dust. Despite its compact size and 1.8" full-range driver with passive radiator, Sony’s Sound Diffusion Processor produces a surprisingly wide soundstage.
