Analysis of acoustic design Ultrasone Edition 10

The Ultrasone Edition 10 headphones are made with an acoustic design of an open type.

Due to the open type, the headphones do not have noise isolation - the surrounding people hear the music from the headphones well, and the listener can hear ambient sounds.

Headphones without noise isolation are well suited for home and studio in a quiet environment, as well as on the street with active traffic, allowing you to notice the danger in time.

Headphones without noise isolation are unsuitable for use in noisy public transport - due to external noise it is necessary to increase the volume level of reproduced music, which is harmful for hearing during long listening. Loud sound is unpleasant to passengers nearby. In a studio, while recording vocals or instruments by a microphone, the open headphones are likewise not suitable, because sound from the "minus" from the headphones will fall into the microphone.

Analysis of the sensitivity of Ultrasone Edition 10 headphones


The sensitivity of the Ultrasone Edition 10 headphones is 112.05 dB/V SPL by the voltage and 97.45 dB/mW SPL by the power. The sensitivity by voltage reflects the relative "loudness" of the headphones among others - the higher the value, so the headphones are louder. The sensitivity by power reflects the efficiency of the headphones. High sensitivity of the headphones means less energy need from the source (for portable devices - less battery power).

Depending on the sensitivity, headphones are best to use with sources of optimum power. If the source is too powerful, then there is a high probability of constantly hearing background noise. If source power is weak, there will be insufficient volume level.

In a quiet environment for the Ultrasone Edition 10 , an amplifier with a voltage level of at least -2.05 dBV at 35 Ohms is recommended for listening to music with a level of 90 dB SPL (without noise isolation). An amplifier with a level above 35.95 dBV is not desirable if the volume control is digital, not analog.

For noisy environments, an amplifier with a voltage level of at least 9.95 dBV at a load of 34.66 ohms is desirable.


If you want to listen to music at a different volume level, you just need to add or subtract a change in dB to 90 dB SPL (for example, for a desired level of 105 dB SPL, add 15 dB and the minimum voltage level for the amplifier is -2.05 dBV + 15 dB = 12.95 dBV).


Analysis of the impedance of Ultrasone Edition 10 headphones

The average resistance at the headphones Ultrasone Edition 10 is 34.66 Ohm.

The resistance affects the amount of current that the amplifier should give to the headphones. If the current is not enough, the sound quality will deteriorate, beginning with harsh in the sound and ending with a banal rattling. In most cases, at low current values, the amplifiers operate in comparable quality to class A, and as the current level rises, the quality decreases toward AB, B, and the clipping zone.

Imagine that you have a water tank, which gradually becomes filled with water. The voltage at the amplifier, this pressure, with which the pump pumped water from the reservoir. If the inflow of water in the tank is lower than the volume that the pump pumps out, then at the pump outlet we collect water and "bubbles". Similarly, with the sound from the headphones, which lacked current from the amplifier.

For a quiet environment, an amplifier with an output current level of at least 22.77 mA in a given class of quality is desirable (preferably orientated to comparable class A) and 90.66 mA for loud.

Тест Ultrasone Edition 10 проведен как черного ящика, без учета стоимости и престижа. Это главный принцип измерений и разработки тестов в RAA.

Считаю, что важно делать не абсолютную оценку устройства, а совокупную оценку при совместной работе сусилителем источника и учетом внешних факторов. Это позволяет эффективно раскрывать потенциал всей связки устройств или делать более оптимальный подбор компонентов.
