Commentary to the report

Vesperaudio leather/alcantara 2 cm earbuds


This is a simplified report for non-professional users ("dummies"), poorly versed in the headphones characteristics and specialized graphs.

Information in this report presents in most simple and clear as possible. Interpretation of the data is simplified as much as possible and accordingly devoid of subtleties and nuances. This is sufficient for an overall assessment, but for a more complete and accurate presentation, the professional report should be studied.

By possible, the characteristics are accompanied by explanations to do reader possibility gradually master a more complex professional report.
For example when choosing a video card, many people do not understand the set of tables with the final data of the test packages. How to understand the relative difference in these figures? In most cases, the unprepared reader is satisfied with only the textual evaluation of the author, without delving into the figures. When the choice of a product is done thoroughly, then the reader gradually deepens into complex tables, mastering information from simple to complex. We made two separate reports: "simple" and "complex". A simple report with explanatory comments will allow you to self-study to gradually understand and professional report.

The table shows the most common variations of sound sources and the scope of use of AMPs and headphones bundles.

The compatibility rating is similar to car analysis based on its ground clearance - on which road the car will move optimal without evaluating the class of the car.

Features and recommendations for Audeze Sine

Analysis of acoustic design Audeze Sine

The Audeze Sine headphones are made with closed-type acoustic design.

Due to the closed type the headphones have passive noise isolation and for the surrounding public the headphones play much quiet than for the listener. External sounds for the listener is on the same quiet level.

Headphones with noise isolation are good for home, when you need not to disturb others while listening to music. It's good in a noisy office, allowing you not to be distracted. In noisy transport playing music in such headphones is more safe for hearing, because due to noise isolation it is possible to listen to music at an average or quiet volume. In the studio, when recording vocals or instruments on a microphone, the closed headphones fit best; Sound from the "minus" of the headphones will not get into the microphone.

Headphones with noise isolation are dangerous to use on the street with active traffic.

Analysis of the sensitivity of Audeze Sine headphones

The sensitivity of the Audeze Sine headphones is 101.71 dB/V SPL by the voltage and 85.37 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 Audeze Sine , an amplifier with a voltage level of at least 2.29 dBV at 23 Ohms is recommended for listening to music with a level of 90 dB SPL (without noise isolation). An amplifier with a level above 40.29 dBV is not desirable if the volume control is digital, not analog.

For noisy environments, an amplifier with a voltage level of at least 14.29 dBV at a load of 23.27 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 2.29 dBV + 15 dB = 17.29 dBV).

Analysis of the impedance of Audeze Sine headphones

The average resistance at the headphones Audeze Sine is 23.27 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 55.96 mA in a given class of quality is desirable (preferably orientated to comparable class A) and 222.80 mA for loud.
