CreativeÂ presented a new model of headphones in May 2007 – Aurvana DJ. It’s a full-sized circumaural model. The new headphones have a wide scope of applications, including professional usage. We constantly hear such daring declarations from manufacturers. But Aurvana DJ is a top model. And so we are very interested in how it performs.
Aurvana DJ is notable for stylish and sturdy design, compact earcup enclosures, and a solid headband.

Dimensions of a headphone with an earcup: 9.2 Ã? 9.2 Ã? 4.5Â cm. But it’s still a little too small for an ear, because the ear hole is just 4.8Â cm in diameter. When you use them for a long time, you start to feel discomfort, as they press into your ear lobe and conch. Leather-clad foam-rubber pads don’t solve this problem.
You can adjust “planting depth” of the headphones on your head on both sides. Retractable plates that can be extended by 3Â cm have seven fixed positions on each side. The leather-clad headband has a soft pad.
The photo below shows the insides of the headphone. A diaphragm is fixed at a small angle to the ear, it’s covered with special tight cloth. The back side of the diaphragm is also cushioned with cloth. Besides, the enclosure contains a piece of polyester wadding. Diaphragm diameter is four centimeters. The headphones have the impedance of 32Â Ohm, audio pressure reaches 105Â dB/mW.
The coiled cord is three meters long. The cord is connected directly to the left headphone, so there are no plugs. The headphones are plugged to a sound source with a mini-jack (1/8″). There is also a bundled adapter to a larger jack (1/4″ TRS).
Let’s proceed to measurements in RMAA 5.6. Let’s have a look at the frequency response graph for a swept sine played back by the headphones.
We use RightMarkÂ? Audio Analyzer PRO for our measurements.
Earthworks M50Â measuring microphone (made in the USA, $2500). Specifications:
- serial number: 9291C
- sensitivity at 1Â kHz: 26.4Â mV/Pa
- Frequency response at 20Â Hz – 20Â kHz: 0.2Â dB
- Frequency response at 3Â Hz – 50Â kHz: +1/-3 dB (trough at 45Â kHz)
For our measurements we use a flat panel (much larger than the earcup) with a measuring microphone inserted into a hole padded with a porolon gasket. One of the headphones is mounted on this panel.
Frequency response graph of Creative Aurvana DJ headphones
Judging by our results, frequency response of the Aurvana DJ headphones is highly non-uniform. It’s rugged along the entire frequency range. It’s strange to see such results demonstrated by full-sized headphones, to say the least.
Now we publish signal spectrums plotted at pilot frequencies.
Signal spectrum reproduced by the headphones playing the 50Â Hz signal
Signal spectrum reproduced by the headphones playing the 75Â Hz signal
Signal spectrum reproduced by the headphones playing the 100Â Hz signal
Signal spectrum reproduced by the headphones playing the 250Â Hz signal
Signal spectrum reproduced by the headphones playing the 500Â Hz signal
Signal spectrum reproduced by the headphones playing the 750Â Hz signal
Signal spectrum reproduced by the headphones playing the 1Â kHz signal
Signal spectrum reproduced by the headphones playing the 2.5Â kHz signal
Signal spectrum reproduced by the headphones playing the 5Â kHz signal
On the whole, Aurvana DJ demonstrates very few harmonic distortions. The spectrum is quite clear. Harmonics Two and Three are predominating. It’s a pity that flatness of frequency response is so horrible.
For subjective tests we plugged the Aurvana DJ headphones to theÂ E-MU 1616mÂ audio interface and Pioneer AX5i DVD-Audio receiver. We compared its audio quality with that ofBeyerdynamic DT 250Â headphones.
The audio quality of Creative Aurvana DJ is on the average level. The main problem is colored sounding at high and middle frequencies. Accent on certain frequencies stresses too many details. Compositions with saturated percussions and cymbals reveal a characteristic sandy tone.
Mid frequencies demonstrate fewer problems. At the same time, sounding at this frequency range is hardly comfortable. The sounding here is not full because of the curve dip in the low mid frequencies and a little accent on the top area.
These problems can be partially solved with a software equalizer. Fortunately, the distortion level is low. At the same time, you cannot solve the problem with colored high frequencies because of distortions.
Audio quality in low frequencies is not bad. LF saturation might have been higher for these closed enclosures.
Thus, we found out that the Creative Aurvana DJ headphones are a usual inexpensive model without surprises. We should point out the tendency to improving audio quality in each new model. That’s very good, of course. In our opinion, the best usage of these headphones is with mobile devices. What concerns professional usage, the sturdy design and closed enclosures are not enough.
