It's time to find out how these things sound in the real world.
Note: Due to the large variation in testing requirements between the products I review, I would like to introduce a more compact 'results' portion of the article starting today. While for larger articles I will still retain my 'classic' format, I hope that for these less involved products I can bring to you an easier article to read.
During my testing of the Halo headphones I found the sound being produced to be quite impressive given the small simple nature of the headphones. However, it takes a fair bit of mucking around to position them correctly which is an important factor given the fact that the drivers themselves are not mounted in anything at all and must be located within the headband evenly.
It's also important to get the right positioning in that it allows the bass not to be lost due to a poor fit around the users head. Bass performance varies a lot depending on how these headphones are worn by the user. If the drivers are located just a couple of millimeters too far away from the ear, low end performance suffers a lot. However, once a balance is found I did not have any problems or complaints, but it is essential that proper position on the users head is found in order to replicate this.
I thought that the mid range sounded surprisingly open and transparent given the limitations involved. Guitars and percussion came through with easy warmth that frankly, I was not expecting.
Even when observing some of my test tracks, Sax solos, that I have heard many times, I was impressed at how calm and mellow they sounded. In fact, these little drivers really should not sound this open and transparent. So, I think at this point we can conclude that the Halo headphones are using quite a decent little speaker to mount in the headband.
Overall, I found musical testing to be surprisingly enjoyable. It's difficult to know what to expect when dealing with a new company, as always.
