# Sony HMZ-T1: Expanded Lens Spacing & Headphone Removal

<div class="document">

<p>I had pre-ordered the Sony HMZ-T1 at the end of 2011, but it finally arrived in March 2012.</p>
<a class="reference external image-reference" href="/media/photo/20120325-hmz-t1/l/IMG_0141.jpg"><img alt="/media/photo/20120325-hmz-t1/s/IMG_0141.jpg" src="/media/photo/20120325-hmz-t1/s/IMG_0141.jpg"/></a>
<div class="section" id="id1">
<h3>Impressions After Using It</h3>
<ul class="simple">
<li>The position of the lenses (displays) can be adjusted horizontally, but **even at the maximum extension, it is too small for my face**. By the way, I am about 190 cm tall. People with large faces, beware!</li>
<li>The sound is very poor. Just as rumored. It's comparable to a 3000 yen headphone. Unacceptable.</li>
<li>The headband is tight. But somehow manageable. People with large heads, beware.</li>
<li>The sides of the screen are blurry.</li>
<li>It causes severe motion sickness. Playing games is out of the question.</li>
</ul>
<p>Since I couldn’t just leave it as is, I decided to tinker with it a bit.</p>
<a class="reference external image-reference" href="/media/photo/20120325-hmz-t1/l/IMG_0123.jpg"><img alt="/media/photo/20120325-hmz-t1/s/IMG_0123.jpg" src="/media/photo/20120325-hmz-t1/s/IMG_0123.jpg"/></a>
<p>▲ Lenses (displays). It would have been nice if they could be positioned one step further out.</p>
<p>This device shows significant individual differences in compatibility. If you're considering buying it, make sure to try it thoroughly in-store. It would be even better if you could test it with games. Particularly, people with large faces or heads should be extra cautious.</p>

<h3>Disassembly</h3>

</dl>
<p>I began the disassembly process.</p>
<p>You can disassemble it with a #1 Phillips screwdriver and a precision Phillips screwdriver.</p>
<a class="reference external image-reference" href="/media/photo/20120325-hmz-t1/l/IMG_0124.jpg"><img alt="/media/photo/20120325-hmz-t1/s/IMG_0124.jpg" src="/media/photo/20120325-hmz-t1/s/IMG_0124.jpg"/></a>
<a class="reference external image-reference" href="/media/photo/20120325-hmz-t1/l/IMG_0126.jpg"><img alt="/media/photo/20120325-hmz-t1/s/IMG_0126.jpg" src="/media/photo/20120325-hmz-t1/s/IMG_0126.jpg"/></a>
</div>

<h3>Adjusting Display Position</h3>
<a class="reference external image-reference" href="/media/photo/20120325-hmz-t1/l/IMG_0130.jpg"><img alt="/media/photo/20120325-hmz-t1/s/IMG_0130.jpg" src="/media/photo/20120325-hmz-t1/s/IMG_0130.jpg"/></a>
<p>▲ As you disassemble, the display unit becomes exposed.</p>
<a class="reference external image-reference" href="/media/photo/20120325-hmz-t1/l/IMG_0131.jpg"><img alt="/media/photo/20120325-hmz-t1/s/IMG_0131.jpg" src="/media/photo/20120325-hmz-t1/s/IMG_0131.jpg"/></a>
<p>▲ Comparison between the unit at its maximum extension and my glasses (standard ones from Zoff).</p>
<a class="reference external image-reference" href="/media/photo/20120325-hmz-t1/l/IMG_0132.jpg"><img alt="/media/photo/20120325-hmz-t1/s/IMG_0132.jpg" src="/media/photo/20120325-hmz-t1/s/IMG_0132.jpg"/></a>
<p>The top of the display unit. The position is synchronized using gears.</p>
<p>Initially, I thought it would be easy to extend the position, but there are many parts it bumps into, making it quite challenging.</p>
<p>However, there is a bit of leeway in the chassis, and with some effort, it seems possible to move it 1.5 mm outward on each side.</p>
<a class="reference external image-reference" href="/media/photo/20120325-hmz-t1/l/IMG_0135.jpg"><img alt="/media/photo/20120325-hmz-t1/s/IMG_0135.jpg" src="/media/photo/20120325-hmz-t1/s/IMG_0135.jpg"/></a>
<p>By extending the holes outward, the range of motion is increased. I cut off the obstructive pins and protrusions on the display side. This reminds me of when I used to tinker with mini 4WD and toy guns.</p>
<a class="reference external image-reference" href="/media/photo/20120325-hmz-t1/l/IMG_0136.jpg"><img alt="/media/photo/20120325-hmz-t1/s/IMG_0136.jpg" src="/media/photo/20120325-hmz-t1/s/IMG_0136.jpg"/></a>
<p>Even the white gear parts were shaved down at the interference points.</p>
<a class="reference external image-reference" href="/media/photo/20120325-hmz-t1/l/IMG_0133.jpg"><img alt="/media/photo/20120325-hmz-t1/s/IMG_0133.jpg" src="/media/photo/20120325-hmz-t1/s/IMG_0133.jpg"/></a>
<a class="reference external image-reference" href="/media/photo/20120325-hmz-t1/l/IMG_0134.jpg"><img alt="/media/photo/20120325-hmz-t1/s/IMG_0134.jpg" src="/media/photo/20120325-hmz-t1/s/IMG_0134.jpg"/></a>
<p>I assembled it and checked the result. The display unit could be moved until it hit the wall of the chassis.</p>
<p>Originally, the display was designed to be adjustable, but since I'm the only one using this device, I fixed it permanently in this position.</p>

<h3>Removing the Headphones</h3>
<p>The useless headphones are just in the way, so I removed them.</p>
<a class="reference external image-reference" href="/media/photo/20120325-hmz-t1/l/IMG_0127.jpg"><img alt="/media/photo/20120325-hmz-t1/s/IMG_0127.jpg" src="/media/photo/20120325-hmz-t1/s/IMG_0127.jpg"/></a>
<a class="reference external image-reference" href="/media/photo/20120325-hmz-t1/l/IMG_0128.jpg"><img alt="/media/photo/20120325-hmz-t1/s/IMG_0128.jpg" src="/media/photo/20120325-hmz-t1/s/IMG_0128.jpg"/></a>
<a class="reference external image-reference" href="/media/photo/20120325-hmz-t1/l/IMG_0137.jpg"><img alt="/media/photo/20120325-hmz-t1/s/IMG_0137.jpg" src="/media/photo/20120325-hmz-t1/s/IMG_0137.jpg"/></a>
<p>You can't remove them just by unscrewing; you need to cut off some parts.</p>
<a class="reference external image-reference" href="/media/photo/20120325-hmz-t1/l/IMG_0138.jpg"><img alt="/media/photo/20120325-hmz-t1/s/IMG_0138.jpg" src="/media/photo/20120325-hmz-t1/s/IMG_0138.jpg"/></a>
<p>Removed.</p>
<a class="reference external image-reference" href="/media/photo/20120325-hmz-t1/l/IMG_0139.jpg"><img alt="/media/photo/20120325-hmz-t1/s/IMG_0139.jpg" src="/media/photo/20120325-hmz-t1/s/IMG_0139.jpg"/></a>
<p>When actually using it, I use it with a different set of headphones like this. These are the Sony MDR-RF7100.</p>
<a class="reference external image-reference" href="/media/photo/20120325-hmz-t1/l/IMG_0144.jpg"><img alt="/media/photo/20120325-hmz-t1/s/IMG_0144.jpg" src="/media/photo/20120325-hmz-t1/s/IMG_0144.jpg"/></a>
<p>Wearing it.</p>
<p>A colleague said I looked "like a futuristic Yakuza."</p>
