The Sennheiser HD 25 are no-fuss, lightweight, on-ear headphones. As wired-only headphones, their comfortable design with a neat headband that splits for added stability aims at DJs or anybody who wants to be the life of the party. Their long cable works for reaching around equipment while staying connected. You can flip your left ear cup back to help you mix and sync tracks without removing the headphones. Besides tweaks with useability in mind, these don't add much in the way of technological advances, but they're also an industry standard for DJs.
Our Verdict
The Sennheiser HD 25 are passable for sports and fitness. Owing mainly to their comfortable, splitting headband that offers good stability, particularly as on-ears go, you can lift weights with these headphones. Their flat sound signature offers a good amount of boom on kick drums, even if it rolls off lower bass frequencies, and the rest of the range plays back clearly to motivate your workout. However, they're wired-only, so you're limited by device connectivity, and the cable can snag on equipment. Plus, they lack an IP rating, meaning they need to avoid dust and rain.
- Comfortable design.
- Split headband for better stability.
- No controls or microphone.
Not very portable and wired-only.
The Sennheiser HD 25 are inadequate for travel. These on-ear headphones lack active noise cancelling, so they only muffle high-frequency environmental noise a bit, leaving rumbles, din, and chatter virtually unaffected. This absence of noise cancelling means your environment will compete with your ability to hear your audio via the flat sound signature, which rolls off low frequencies and adds extra boom to bass, with a clear mid-range and slightly uneven top-end. While they're comfortable and lightweight headphones, they're wired-only and don't fold down smaller.
- Comfortable design.
- Poor noise isolation.
- No controls or microphone.
Not very portable and wired-only.
The Sennheiser HD 25 are bad for office work. While they're closed-backs, the passive-only isolation doesn't effectively block out noises like coworkers or HVAC systems. The wired-only cans' lack of a mic also means you'll need a separate one for online meetings. Still, their lightweight design is comfortable, and their flat sound signature ensures voices and lead instruments sound pretty true-to-life, so it's decent for music or podcasts.
- Comfortable design.
- Poor noise isolation.
- No controls or microphone.
The Sennheiser HD25 can't connect wirelessly because they're wired-only passive headphones.
The Sennheiser HD 25 are middling for wired gaming. They're limited by the absence of a microphone, so you'll need an outboard mic if you play with others. They also require some care to ensure a consistent sound between wears. The closed-back design doesn't yield an open sound, and they don't meaningfully interact with your ears' pinna for an immersive feel. Still, for fans of comfortable, lightweight headphones for solo gaming and a frequency response that renders dialogue clearly, they might work for you.
- Comfortable design.
- No controls or microphone.
- No additional surround sound or EQ.
The Sennheiser HD 25 have satisfactory audio reproduction accuracy. Their peaks and dips performance provides a smooth flat sound signature. While the low-bass frequencies roll off, the high-bass offers some extra boominess to an otherwise clear mid-range and mostly bright treble. There's a touch of de-emphasis in the low-treble to warm up vocals, while a blast of high-treble adds airiness to the tuning. The stereo mismatch is very good, with tight tolerances, and there's no audible harmonic distortion. However, the closed-backed on-ears don't interact with your ears' pinna, so audio isn't very immersive.
The Sennheiser HD25 have poor noise isolation performance. As passive on-ear headphones without active noise cancelling, they only muffle high frequencies while leaving low and mid-range noises unaltered. As a result, noises like the rumbles of big rigs on the street still reach your ears, while sounds like old squeaky brakes are slightly quieter, though audible.
The Sennheiser HD25 don't have a microphone.
The Sennheiser HD25 have disappointing frequency response consistency. Generally, on-ears can be slightly finicky compared to over-ears because they don't rest the ear pads around your ear, which is a smoother surface on virtually everyone, rather than the contours of an ear. If your head is large, the bass tends to sound quieter with these cans. While the consistency is a bit better if your head is small, glasses can alter the sound, too, but not very dramatically.

Popular Headphones Comparisons
The Sennheiser HD 25 are plastic on-ear headphones with analog connectivity. Each model in the HD 25 line is quite similar, with minor differences in accessories and creature comforts. In the tier below are the more spartan Sennheiser HD 25 Light with a cumbersome Y-cable, and above are the Sennheiser HD 25 Plus, which use a different connector to the ear cups and include a carry pouch, spare earpads, and a coiled cable. Sennheiser also produces a Bluetooth-capable entry, the Sennheiser HD 250BT, or you can consider the Pioneer DJ HDJ-CUE1BT on-ears for wireless or wired versatility. While you can use most analog headphones for DJ sets, this line has some unique features, like a splittable headband, that set them apart from other popular picks like the Audio-Technica ATH-M50x, which fit over-ears instead but have a broadly similar bass bump.

The AIAIAI TMA-2 DJ and the Sennheiser HD 25 headphones are designed for DJs or fans of on-ear designs and swappable cables. The AIAIAI sound more bass-heavy and warm with very de-emphasized mids and treble. Their design is modular, and you can swap out and replace nearly every component of the AIAIAI with other parts, but as is, they're less comfortable, and you can't pivot the ear cups at all. The Sennheiser cans offer a bump in the high-bass with a clearer mid-range and brighter treble, which is more versatile, but it can depend on your tastes. The unique splitting headband allows them to fit with better stability and comfort. The Sennheiser are the better pick for most DJs. Still, if you're a bass head, the AIAIAI are the better choice.
Both the Sennheiser HD 25 and the Sony MDR-7506 have utilitarian designs prioritizing repairability. You can replace almost every part of these headphones. However, besides the metal hinge that flips the Sennheiser's left ear cup forward or backward, they're plasticky headphones but lightweight. Their long cable is straight and detachable, and these headphones fit on your ears. The Sony are plastic, but they have metal integrated throughout the housing. While they're over-ears, they have shallow ear cups. Their long coil cable is surprisingly hefty but not detachable, even though you can unscrew and replace the drivers. They're designed for monitoring sound production, while the Sennheiser are meant for DJing and casual listening.
The Audio-Technica ATH-M50x and the Sennheiser HD 25 are both popular wired headphones for enthusiasts and DJs alike. One distinction is that the Audio-Technica are over-ear headphones and weigh much more than the lightweight Sennheiser. They can fold down smaller with a travel bag. You get two extra detachable audio cables, and both use different but proprietary cable connectors. In contrast, the Sennheiser fit on-ears. They feel comfortable and don't clamp as hard as the Audio-Technica. The headband can split, which is unique and helps to stabilize the fit.
The Sennheiser HD 25 and the Sennheiser HD 280 Pro 2016 are both aimed at enthusiasts. As a set of on-ear headphones, the HD 25 fit and feel quite different, weighing quite a bit less, and have some added benefits like the left ear cup, which you can flip forward or backward. They have a detachable cable and unimpressive noise isolation, but a unique splitting headband adds security to their fit on your head. Typically, they're used for DJing. The over-ear-fitting HD 280 Pro 2016 are also plasticky in build, notably chunkier in size, and clamp harder. You can collapse them down, which is handy. They're designed for studio use with a different tuning.
