Due to their low weight and the option of one-ear listening, the HD 25 headphones are indispensable for mobile monitoring. The closed-back HD 25 are purpose-designed, professional monitoring headphones offering high attenuation of background noise.

Capable of handling very high sound pressure levels and of extremely robust construction, these headphones perform exceptionally well in loud environments, e.g. ENG, sound reinforcement, studio monitoring and audio equipment testing. Ideal monitoring headphones for cameramen and DJs, these are a pair of true sound professionals’ working headphones.

FAQ

  • What is the maximum SPL of a dynamic microphone?

    It is a common saying that dynamic microphones just have no maximum SPL.
    This saying is not technically exactly correct but for every day use use of dynamic microphones you will not find gain limitations. At SPL levels above 160 dB some mechanical problems might occur (for example the voice coil might crash onto the magnet) but these SPL levels are very hard to find in real world.
    Here at Sennheiser we use dynamic microphones for distortion measurements on loudspeakers at very high sound pressure levels. At Sennheiser we have measured the SPL and THD inside a large 2" driver/horn combination with a MD 421. The max SPL this combination was able to produce was 150 dB and the THD level recorded by a MD 421 was below 1% (produced by the driver not by the mic)
    So as a conclusion we can state the MD 421 has no maximum SPL limitations for practical use. However if using dynamic microphones at high SPL levels a user should be aware that the very high voltage (up to several volts) delivered by the microphone might cause problems when connected to mic preamps.

  • Sound in only one ear or general sound issues.

    If the headphones have sound in only one ear or differing sound levels in each ear or the sound in general is not what you expected then it needs to be determined where the issue lies - with the headphones or with the audio source.

    The first thing to do is ensure that you have the audio plug of the headphones connected securely into the audio device. A properly connected cable should not wiggle. If the plug wiggles that could indicate a loose connection. NOTE: This could be a result of the cable not being plugged all the way in or it could be a faulty input or sometimes if the device you are connecting to has a case on it the case will prevent the cable plugging in correctly.

    The next thing to do is to check and make sure that there is no debris (ie: no dust or lint) in the headphone jack of the audio source that may be inhibiting connectivity and causing sound issues.

    The next thing to do is to check that the connecting jack is clean. If oils from the hands gets builds up on the plug or sweat evaporates on the plug the salts and grime may prevent proper contact from occurring. The connecting jacks can be cleaned using a basic alcohol wipe.

    The next thing to do is to try the headphones on a different audio source to check that it is not the original audio source (or a setting on the audio source) that is creating the issue. If you connect to an alternate audio source and the issue is not there then you know the headphones are fine and the original audio source is the issue. NOTE: Many modern audio devices have audio limit pre-set at the factory and these limit need to be changed to get the full audio signal out of the device and to the headphones.

  • What are the primary differences between the different HD 25 models?

    Currently Sennheiser offers three (3) models in the HD 25 line

    • HD 25 LIGHT

    - The HD 25 LIGHT is the essential sound of a HD 25 with a simplified headband.

    - Impedance = 60 Ohms

    - Frequency response = 30-16,000 Hz

    • HD 25

    - The HD 25 is our legendary HD 25 headphone with splayed headband and straight cable.

    - Impedance = 70 Ohms

    - Frequency response = 16-22,000 Hz

    • HD 25 PLUS

    - The HD 25 PLUS is our legendary HD 25 headphone with coiled cable, an additional straight cable, a second set of ear cushions and a protective pouch

    - Impedance = 70 Ohms

    - Frequency response = 16-22,000 Hz

    These models offer the same sound signature as the legendary HD 25 and sound signature of the headphones is the same across the three models.

    Punchy and Durable

    Everyone should have a pair of HD 25s at 150 bucks.

    PRO:

    Whether I'm tossing them in briefcase, falling asleep with them on, or going on a run, I don't have to worry about the HD 25s losing their punchy clarity and great tone.

    CON:

    They're not the most comfortable headphones in the world, but that's pretty inherent to being on-ears.

    BEST USES:

    Casual listening, studio monitoring, travel

    BOTTOM LINE:

    I would recommend this to a friend.

    Not gonna look for other 'phones

    HD-25's were designed with efficiency in mind. Attention to detail in craftsmanship is evident as well - from tiny bolts to how smooth the pads can be adjusted in three planes. The sound is mind-blowing*, no coloration and I didn't notice any holes in frequency spectrum either. *Actually the sound is so clear that on higher volumes certain sounds with fast attack tend to have a slightly uncomfortable feeling of ticking inside the brain - tight rimshots in particular. My favorite headphones nevertheless, probably wouldn't exchange for any others .

    PRO:

    Amazing sound - loud and clear, lightweight, durable as hell, people can't believe that such minimalist headphones sound like that.

    CON:

    The padding isn't perfect, I recommend custom ear pads.

    BEST USES:

    So far used for standard music listening on some correct setup and smartphone as well, DJing, and mixing.

    BOTTOM LINE:

    I would recommend this to a friend.

    sound is amazing, driver connection is frustrating

    Excellent, but connection issues need a fix

    PRO:

    Excellent sound, excellent fit, excellent build quality

    CON:

    The connection to the individual drivers often cuts out. It's a known issue and the solution is goofy and incomplete. You have to bend the coils inside the connection with a pin needle. It's frustrating.

    BEST USES:

    DJ, live audio

    BOTTOM LINE:

    I would not recommend this to a friend.
