The red Phone Holder and Tube Clamp from Hamilton Stands allows you to view your smartphone while on stage or in the studio by attaching to music and microphone stands. The phone holder uses a scissor-action clamp to securely hold your smartphone in place, even during high vibration recordings. The clamp has enough give to accommodate a wide variety of smartphones, and can also be used with smartphones in protective cases. The phone holder is attached to a 6.0" steel gooseneck, allowing you to position your phone ergonomically. The tube clamp is compatible with any 5/8" to 1.0" diameter stand.
