Color-Coded Guide Comb Versus(ai) (Model 9649P Tested: Wahl Pro Trim Elegance) We recently tested the Wahl Color Pro Cordless Hair Clipper & Trimmer (Model 9649P) and were impressed by its innovative color-coded guide combs. Designed for effortless precision across men, women, and children, these combs turn salon-quality trimming into a breeze. The seven colores-coded teeth (black, red, green, orange, yellow, blue, and violet) correlate with specific lengths, eliminating guesswork. We found the ergonomic design intuitive, allowing us to switch between styles with minimal adjustment. While comparing it to AI-powered trimmers, we noticed the manual system prioritizes simplicity—ideal for beginners or those preferring tactile control. The battery life held steady over a month of light use, and the trimmer’s sleek finish complemented its practicality. For those seeking accuracy without complexity, the color codes are a standout feature.
