Since it is supposed to be attached to VR goggles, it is very small and lightweight, so it has to be attached to a separate battery for driving, but it still does not feel particularly uncomfortable to wear. The case seems to contribute greatly to the low price by manufacturing it in-house using a 3D printer. The models sent to us are still rough in construction, but since they have introduced a highly accurate 3D printer, it will be a more accurate case in the future. The material of the case is a lightweight and high-strength thing woven with carbon fiber.
There are three types, a model with volume in a case with a belt loopVHA-5240Aand no volumeVHA-5240Band a model that omits the belt loop and makes it an earphone amplifier that can be used anywhereVHA-5240C。
The connection method is input to the amplifier from the earphone jack of the VR goggles. It is also compatible with goggles that have separate outputs on the left and right. The output of the amplifier is also compatible with both the normal stereotype and the left and right independent types. If the VR goggles do not have volume adjustment, you can use the VHA-5240A with volume to adjust the volume arbitrarily. Also, if the goggles have a volume adjustment, use the VHA-5240B without volume. Thanks to the elimination of the volume and the significant increase in the input impedance, the sound is more accurate and richer than that of the 5240A.
Try watching VR while actually wearing it. VR images bring a considerable sense to the visual part. Even so, 360-degree environmental sound is indispensable for realizing virtual reality, and the quality of binaural sound affects reality. I'm not sure if there is any merit in using VR in the first place for a live music video, but I think the sound has an increased sense of depth. Personally, I have the impression that the binaural effect is clearer with the VHA-5240 in the video of traveling around in a foreign land. In other words, it is more accurate to say that the sense of distance from the source of the sound has become easier to understand, or that the sense of reality has increased in conjunction with the image. Perhaps because of this, those who enjoy games have commented that it has become easier to understand the distance and position of the surroundings, so it can be said that it is a product suitable for games that allow you to enjoy virtual reality.
The price is also low, so it may be the perfect product for those who want to immerse themselves in virtual reality more!
