Black metal Stereo Audio Cable Metal 1/4" 3.5mm 4ft long Male to Male AUX Cable. This size works great between my mixer board and Power Amp. Plenty long enough to switch where I need it the most. Solid metal connectors that feel professional when plugging in. not a cheap cable but not too heavy either. Good electrical connectivity for my Karaoke sound system. I will be getting more of these to hook in Feedback eliminators and compressors for when I do live shows and make recording. A great buy!
