Review on 🎧 Aukeer 3.5mm Audio Cable, 2-Pack - 30cm Coiled 3.5mm Headphone Cable, 90° 1/8" TRS Jack Male to Male Stereo Aux Coiled Cord (Up to 50cm) by Cesar Danger

I use them with JBL portable speakers and car stereos. In terms of sound, a wired connection can hardly be surpassed. I think it just sounds better than Bluetooth. With cords that short, you'll hardly notice them, but the spiral part allows for a little stretch, which makes using such a short cord more convenient. Thought they were a bit pricey but not too bad for two of them.
