Hey everyone! Joseph over here and to be succinct, I've been working with @thatonenoob to provide tech/audio reviews and updates for the last year and a half. I'm an audio enthusiast myself, and about a month back, I received an invitation by the Sony Singapore Team to join a Sony Experience event alongside the Hong Kong High End Audio Visual Show. I'll be posting more updates on this thread as the event moves along, so feel free to ask me any questions. Those who would like to know more about Sony's other releases during this event can take a look at the following threads that I have created: - Sony DMP-Z1 portable high end digital music player - Sony's Three New Earphones I'm also on the SEAudio discord channel and will regularly be posting updates there as well. If you'd like to hear from me, you can join our server using this link For those of you who would like to watch a video overview of what to expect from the Z7Mk2 as well as some of the underlying technology, please check out the video below. We have as well recorded technical interview with the engineers that you guys can watch over here: Otherwise, lets dive in to what we're able to find out so far. Specifications ______________________________________________________________________________________ Layout: 1. Design / Philosophy 2. Engineer Technical Video Interview 3. General Impressions ____________________________________________________________________________________________ 1. Design / Philosophy A closed back headphone typically presents engineers with a lot of challenges as compared with an open back headphone, so in this regard, I'm appreciative of Sony constantly trying to push forward with their closed back designs. Their original Z7 was one of the more premium closed back options on the market that may had a few flaws. Here, the Z7MK2 aims to improve the original Z7 by incorporating new technologies that exists in the current flagship, the MDR-Z1R. The driver here in the Z7 is a huge 70mm driver along with aluminium coated liquid crystal polymer diaphragm. The advantage of the liquid crystal polymer, as discussed in the IER-Z1R thread, is that it creates less vibrations and adds minimal colour to the sound, especially in the upper frequencies. The fibonacci patterned grill was also used to reduce resonance, in addition to a new "Beat Response Control", which is a special acoustic port that supposedly controls the air flow behind the driver. These vents are adopted from the design of the MDR-Z1R, and fixes some of the issue faced by the original Z7. During the Audio Visual show, I had a chance to talk to Shunsuke Shiomi, an engineer who is part of the team that designed the Z7s. He said in the MK1, the Z7's venting port was only on one small area on each of the earcups, and resulted in uneven venting within the headphone itself. In the MK2, the ports are surrounding the rim of each earcup (see pic below) and alleviates the initial issue. These are all measures taken to reduce the resonance as a result of it being a closed back headphone. A much bigger magnet (double the volume of the original Z7) was also utilised in the production of the new Z7, hoping to gain better control and detail out of the headphone. Compared to sound, the comfort of this headphone just as important for the engineers here at Sony. The earpads were very plush and of great quality as well. Sony product detail handout is incessant about the quality of the sewing done on the various part of the headphones. They also mentioned the use of urethane foam cushion for the earpads, that have moisture absorbing/releasing characteristics that can aid in the discomfort when using leather earpads for long periods. The height adjustments and earcup swivelling are reminiscent of the Z1R; very well built and confidence inspiring, with proper contributions to the user's comfort. According to the marketing team, a common feedback from customers who owned the MK1 is that the headphones creak when you swivel the earcups but rest assured this problem did not exist in all the MK2s that i played with today. In order to maintain all these new technologies while trying to keep prices low, these headphones actually made in Thailand, but fret not, because Sony still employs very strict quality control. These headphones are made in the very same factory that produces the widely known MDR7506!
