Having a GoPro to record is great. Small, fast, simple. However, the sound quality can be a little, well, not the best. If you want to improve the sound in your videos, this will come in handy. If you have a GoPro Here 5 or later, you will need to purchase a USB-C to 3.5mm adapter. Don't buy cheap ones and get a GoPro, it's worth the extra money. The only downside to the kit is its size. The adapter is huge compared to the camera. Either way, the best sound quality in your videos is worth it.
