Sony HMZ-T1: Expanded Lens Spacing & Headphone Removal

Impressions After Using It

• 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!
• The sound is very poor. Just as rumored. It's comparable to a 3000 yen headphone. Unacceptable.
• The headband is tight. But somehow manageable. People with large heads, beware.
• The sides of the screen are blurry.
• It causes severe motion sickness. Playing games is out of the question.

Since I couldn’t just leave it as is, I decided to tinker with it a bit.

▲ Lenses (displays). It would have been nice if they could be positioned one step further out.

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.

Disassembly

I began the disassembly process.

You can disassemble it with a #1 Phillips screwdriver and a precision Phillips screwdriver.

Adjusting Display Position

▲ As you disassemble, the display unit becomes exposed.

The top of the display unit. The position is synchronized using gears.

Initially, I thought it would be easy to extend the position, but there are many parts it bumps into, making it quite challenging.

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.

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.

Even the white gear parts were shaved down at the interference points.

I assembled it and checked the result. The display unit could be moved until it hit the wall of the chassis.

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.

Removing the Headphones

The useless headphones are just in the way, so I removed them.

You can't remove them just by unscrewing; you need to cut off some parts.

Removed.

When actually using it, I use it with a different set of headphones like this. These are the Sony MDR-RF7100.

Wearing it.

A colleague said I looked "like a futuristic Yakuza."
