Dale: It’s really the same with any genre or sub-genre of music, that the sound from different artists and tracks can vary a lot, so having more than one headphone is a plus. When only one headphone is available at a particular time (portable use especially), one option is to use a headphone that can accommodate a wide range of genres, in which case there may be compromises to consider. Another option is to carry two headphones – one on the head or around the neck and another in a carry case. Some of the small headphones can make this easy to do.
However, we also move up to high-resolution audio files, as well as a wide variety of sources, including plugging in directly to a PC or Mac, using USB DACs (digital-to-analog converters), and employing high-quality, dedicated portable players and amplifiers. Finally, we compare the headphones to some of our go-to models, both in their class and price point, as well as a level or two above to find out if they can punch above their weight.
What I’m saying here is that it’s better to own three $100 headphones than one $300 headphone. Or three $300 headphones than one $900 headphone. Why? Because most people don’t limit their playlist to strictly one genre. And following the logic from Rule #2, the right headphone-music pairing is going to be better than one expensive headphone paired to the wrong music.
Of the tested codecs we met, aptX and aptX HD fared the best out of all our candidates. While that may seem strange to say, on the whole their results were right where they needed to be in order to stand in for a wire for commuters, and listeners over 40. You’d really only run into issues at high volumes (90+dB), so while aptX isn’t quite able to keep up with CD quality, aptX HD is able to get extremely close to the mark with a little processing creativeness. Both codecs fall short in the highest frequencies a human could potentially hear, but the vast majority of people can’t hear sounds over 18kHz anyway.
