Sennheiser HD 25 Light: HD-25 Sound at just 120 Grams
· re:union Radio editorial · 3 min read
Sennheiser HD 25 Light: closed-back on-ear headphones with 120g, 70 ohms, and 120 dB – all the specs and how it differs from the full-sized HD 25.
The Sennheiser HD 25 Light is the slimmed-down version of a headphone you'll spot on countless heads in DJ booths. The line didn't even originate in clubs: Sennheiser has been building the HD 25 since the late 80s, initially intended for TV and film productions. The Light version adopts the sound formula and cuts down where weight is concerned – it tips the scales at just 120 grams.
At a glance
- Closed-back on-ear headphones with dynamic transducers, weighing 120 g
- 16–22,000 Hz, 70 ohms, up to 120 dB sound pressure level
- Detachable, straight 1.5m cable with 3.5mm jack and 6.3mm screw adapter
- Ear pads and cable are field-replaceable, according to Sennheiser
HD-25 Sound in a Slim Form
Sennheiser describes the HD 25 Light as closed-back monitoring headphones in an on-ear design for DJs, broadcasting, and outdoor recordings. According to the manufacturer, lightweight aluminum voice coils ensure high sensitivity, and the sound signature is said to deliver transparent highs and precise mids – the same formula as the full-sized HD 25.
The difference lies in the construction: The headband is a continuous design and rather thinly padded – Bonedo, in its review, speaks of “constructive simplifications” compared to the sister models HD 25 and HD 25 Plus. The earcups are rotatable, allowing you to cue with only one side on your ear. The box includes headphones, a detachable cable, a screw adapter, and safety instructions – nothing more.
The Technical Specifications
The story behind the numbers is exciting. The specialist magazine Bonedo points out that the old Light model only covered 30 to 16,000 Hz and reached 114 dB. The revised version received new drivers and now matches the HD 25: 16 to 22,000 Hz, 70 ohms, 120 dB.

Who the HD 25 Light is For
The weight is the key argument. At 120 grams and with its simple headband, the Light targets DJs who are often on the go and need mobile monitoring. Sennheiser explicitly mentions parties, streaming from your room, and FoH work. Bonedo recommends it for FoH applications, preparing DJ sets, and anyone looking for a particularly lightweight model.
Because it can handle high levels and has a closed design, it's suitable for pre-listening in loud environments – precisely where you need to work precisely during transitions. Our DJ Tip: How to Mix Perfect Transitions with the EQ shows you how to cleanly balance the frequency bands.
Light or Full-Sized HD 25?
Sonically, according to the spec sheet, nothing separates the current generation anymore. Bonedo cites the better-padded headband and single-sided cable routing as advantages of the regular HD 25. If you want the complete package, check out the Sennheiser HD 25 Plus. For the Light, note: Sennheiser sells spare parts like ear pads, headbands, and cables separately.
