On the other end, headphones with high impedance have more electrical resistance. This means that you will naturally need more power output from your audio source to allow these high impedance headphones to achieve their optimal sound and volume. This boost of power usually makes for a wider representation of audio frequencies as well as more impactful dynamic range. There is a large variety of different headphone amplifiers and portable audio players that have higher electrical output, but as mentioned earlier, impedance also occurs in the audio source. High impedance headphones are usually estimated at 25 ohms and above.In regards to Moore’s law, technology is simply getting better and better. In 2019, headphones with an average load impedance of 32 ohms are becoming the new audio standard for a high-quality sound that doesn’t cost a fortune or requires an expensive headphone amplifier. Most smartphones are suitable for powering these headphones, which means the sound quality and musical experience we have will get better and better in time. Our new AU Stream ANC headphones meet this new 32-ohm standard and sound great with standard smartphones, and since they aren’t considered low impedance (<25 ohms), you can generally power these a bit more, resulting in a richer and louder sound.Impedance matching doesn’t simply mean matching impedance numbers of your audio source and headphone. Finding the most appropriate match depends on more factors including the power of your amplifier or audio source, your headphones “load impedance”, your “output impedance”, and your headphone sensitivity (a whole different but relevant topic). There is a lot more to cover in regards to impedance, so stay tuned for future articles where we cover impedance matching, headphone sensitivity, and much more that will empower you to make the best decision on your next pair of headphones.

Overall, we have a 45-step quality control process because we truly care about providing the best value and listening experience possible. Every time.What about when you get your headphones and want to test them yourself? There are some great resources out there that you can download free frequency sweeps (with voiceovers) to test the Audio Signature yourself. We would recommend AudioCheck.Net for various test tones and frequencies.Finally, It wouldn’t make much sense to use different songs with different sonic qualities when comparing specific sections of the frequency spectrum such as the low end. Some songs in different genres don’t even have audio information below or above certain frequencies because of how they are recorded or filtered. Because of this, it is generally useful to use a spectrogram to visually see audio information of your file while listening, so that you can intentionally listen for qualities in each frequency range. There are a few browser-based spectrograms out there, but you can also download a free spectrogram application from this link: https://www.sonicvisualiser.org/

Aside from a flat frequency response curve, comfort and mobility are also considerable factors in the modern-day “mobile studio” in regards to headphones. As Active Noise Cancellation (ANC) is becoming more and more common, artists and music lovers are more frequently bringing their laptops to coffee shops and libraries to work on or listen to their music without outside noise being an issue. Our AU Stream ANC headphones are a great example of a quality pair you can take out in the field when you are arranging, mixing, or recording samples for your tracks. They are even perfect for everyday listening or studying when you need to drown out the world for a moment.Inspiration can strike at a moments notice. Being so, it is important to have the right headphones for the job. Our AU Stream ANC headphones are lightweight, portable, durable, and most importantly comfortable. Did we mention that they also sound amazing? Try them out for yourself!
