My fiancee purchased the HiBy R4 from MusicTeck. I love it. It looks great and sounds phenomenal! The R4 includes a hole on top for a strap. I saw that MusicTeck sells the strap, so I ordered it.
The strap is about 6 inches long by 1 inch wide and comes with a metal buckle to tie to the R4. The installation is not difficult; it is good that HiBy uploaded a video tutorial on Youtube on how to attach the strap.
The picture on the listing is just the box it comes with, not the actual strap. I included photos so you can see the actual product. It’s very high quality. The strap has the HiBy logo and the “Make Music More Musical” slogan embroidered.
This strap comes in three colors: silver/black for both the black and silver R4 models, orange/black for the orange R4 and green/black for the green R4 model.
While the strap is unnecessary for the R4 to work, it serves a practical purpose. It helps prevent the device from slipping out of your hand, providing a secure grip. Additionally, it adds a touch of style to your R4, making it a nice-to-have accessory.
