General Description
The Trefoil brand, which has been linked to the music scene for a long time and is connected uniquely to the beginnings of Hip Hop in the 1980s, now proudly underlines its music affinity with the Sennheiser HD 25-1 II, which has been one of the most successful monitoring headphones for over 20 years. Now, it has been given a design makeover by adidas Originals, featuring the brand's iconic "3-Stripes" design and blue color identity.
These headphones handle a high sound pressure level, with crystal clear highs and crisp bass. Along with the adidas Originals design, these headphones ensure a true Sennheiser sound experience.
What the experts are saying:
"The best sound and feel of any DJ headphone I have ever had" -Darren Holland, Live DJ Underground and head of Baldeelox Records
"We use Sennheiser HD 25 on all our gigs. Have tried and tested other headphones but none of them have the same full range and sound as these!" -Soulmagic, Artist
"The Sennheiser HD headphones are the best headphones out there. I love listening to music, especially when I'm traveling or getting ready for a game, and nothing makes my music sound better. Plus, the noise isolation is incredible, all I hear is what I want to hear." -Eric Berry, Kansas City Chiefs
"These Headphones sound as good as my studio monitors, I can really hear all the nuances to my production with these." -Jay Tripwire, DJ
"I Love my Sennheiser HD-25 not only for their rugged design which has kept them alive through but also all the hard things i've put them through both as DJ and day to day usage. I love them for their brilliant sound quality. The HD-25's is a DJ's best friend!" -Johannes Drakenberg, Radio4by4.com

Glossary
| Cable length |
| The cable length is usually measured between the anti-kink sleeves of the cable (cable length without connectors). |
| Frequency response (headphones) |
| The frequency response of a pair of headphones is given within limits defined by the manufacturer. |
| Impedance |
| Impedance expresses the AC resistance of a microphone or a set of headphones. It is dependent on frequency and is given at 1 kHz as the so-called nominal impedance. Impedance is measured in ohms. In recent years, an industrial standard has developed, setting the impedance of headphones at 50 or 600 ohms. Sennheiser headphones are manufactured according to this standard, thus practically ruling out connection problems. With microphones, the input impedance of the following microphone amplifier should have at least three times the value of the nominal impedance, in order to prevent it from unnecessarily attenuating the microphone signal. |
| Sound pressure level (SPL) |
| Due to the impractical numerical values, the sound pressure is usually given as the logarithmic value of the sound pressure level according to the equation: dB SPL = 20 x log (po / 0.00002 Pa). The abbreviation SPL (sound pressure level) is added in order to make a clear distinction from other uses of dB. The reference sound pressure, which is at the same time the threshold of hearing, is then 0 dB SPL. The threshold of pain is 140 dB SPL. A difference in the sound pressure level of 1 dB is just about perceptible, while a doubling of the sound pressure corresponds to 6 dB and a doubling of the volume corresponds to a rise of 10 dB. |
| Total harmonic distortion (THD) |
| Total harmonic distortion is a measure of non-linear harmonic distortion and is given in %. Non-linear harmonic distortions are signals which were not present in the original before the signal was converted by the headphones. These unwanted signals are caused by the diaphragm, whose movements do not precisely move in time with the electric signals that cause it to move. Unfortunately, this is a feature of all electroacoustic transducers. Although it cannot be completely eliminated, suitable steps can be taken to minimise it. However, the user is not interested in why this distortion takes place but in how great the level of distortion must be for it to become perceptible. According to the findings of several research projects, a total harmonic distortion of 1% in the frequency range of 100 to 2000 Hz is imperceptible. Below 100 Hz, the perceptibility threshold lies at 10%. |
