HD 599 vs RS 120-W Specs
Acoustic Design
The Sennheiser HD 599 features an open-back acoustic design. This configuration allows air to pass through the ear cups, creating a wider, more natural soundstage. It is ideal for quiet, dedicated listening environments where sound leakage is not a concern. In contrast, the RS 120-W does not specify an open or closed design in its data. However, its on-ear form factor typically provides more isolation than open-back designs. If you need to keep sound contained within your ears, the RS 120-W is the safer choice for shared spaces.
Connectivity Type
The HD 599 relies entirely on wired connectivity. It includes a 3-meter detachable cable with a 6.3mm jack and an additional 1.2-meter cable with a 3.5mm jack. You must plug it directly into your audio source. The RS 120-W uses digital wireless transmission, offering up to 60 meters of range. It connects to TVs via RCA or 3.5mm plugs through a transmitter. For freedom of movement and TV compatibility, the wireless RS 120-W is superior. For zero-latency wired connections, the HD 599 wins.
Form Factor
The HD 599 uses an around-ear design with velour-covered ear pads and a padded headband. This setup distributes weight evenly, reducing pressure on the ears during long sessions. The RS 120-W is an on-ear model. It is described as lightweight with low headband pressure, but it rests directly on the ears. On-ear designs can sometimes cause fatigue over time compared to around-ear models. The HD 599’s around-ear construction generally offers better comfort for extended listening periods.
Battery and Power
The RS 120-W operates on rechargeable AAA batteries, providing up to 20 hours of playback. It includes a charging dock within the transmitter combo. The HD 599 lists battery as its power source type in its features, yet it is a wired headphone. This data point is contradictory for a passive wired device. Assuming the HD 599 requires no power, it offers unlimited listening time without charging. The RS 120-W requires battery management. For hassle-free continuous use, the wired HD 599 is more reliable.
Audio Features
The RS 120-W includes three specific sound modes: Speech, Music, and Neutral. These profiles allow you to adjust the audio balance for different content types, such as podcasts or movies. The HD 599 uses Sennheiser engineered transducers with aluminum voice coils for high efficiency and low distortion. It does not list adjustable sound modes. If you want customizable audio profiles for TV dialogue, the RS 120-W provides useful flexibility. The HD 599 focuses on neutral, high-fidelity reproduction without digital processing.

Home theater users needing wireless convenience
The RS 120-W connects wirelessly via digital transmission with up to 60m range. It includes a transmitter dock for RCA or 3.5mm TV connections.

Listeners wanting easy on-headphone volume control
The RS 120-W features an ergonomic control dial directly on the headphones. This allows intuitive volume adjustment without reaching for a remote or device.
