It is intended to be attached to VR goggles, so it is very small and lightweight, so you will have to attach a separate drive battery, but there is no particular discomfort when installing it. The cases are manufactured in-house using 3D printers, which seems to have contributed greatly to the low prices. The models that were sent still have rough construction, but since they have introduced a highly accurate 3D printer, it is likely that the case will be more accurate in the future. The case is made of lightweight, high-strength, woven with carbon fiber carbon.
There are three types, with a case with belt loop and a volume modelVHA-5240AAnd no volumeVHA-5240BTwo models and a model that uses earphone amplifiers that can be used anywhere, eliminating the belt loop.VHA-5240C。
To connect, enter the amplifier from the earphone jack on the VR goggle. It also supports goggles that have separate outputs on the left and right sides. The amplifier output can also be used in both normal stereotypes and independent left and right types. For models with no volume adjustments in VR goggles, you can adjust the volume at will if you use the volume-equipped VHA-5240A. Also, if the goggles have volume adjustments, use the no-volume VHA-5240B. By eliminating the volume, the input impedance has been significantly increased, making it a richer sound with higher accuracy than the 5240A.
Try watching VR while actually wearing it. VR video brings a considerable amount of sense into the visual area. Still, 360-degree ambient sounds are essential to achieving virtual reality, and the performance of the binaural sound affects reality. From a sense of perspective, I'm not sure if there's any benefit to using live music videos in VR in the first place, but I think the sound has an increased sense of depth. Personally, I have the impression that the VHA-5240 has made the binaural effect even clearer than the footage of traveling around foreign lands. In other words, it is better to say that the distance from the sound has become easier to understand, and that the reality has become more linked to the image. Perhaps because of this, people who enjoy the game have also heard that the distance and location of the surroundings have become easier to understand, so this product can be said to be more suitable for games that allow you to enjoy virtual reality.
The price is also low, so this may be the perfect product for those who want to be more immersed in virtual reality!
