JBLBAR300M2BLKAMBlack 1 year manufacturer

✓HDMI eARC with 4K Dolby Vision passthrough ensures high‑resolution video and high‑quality audio over a single cable.

✓JBL One App allows wireless control, firmware updates, and easy sound calibration from a smartphone.

How It Compares

vs. JBL Bar 500MK2

Advantages

✓Includes a dedicated wireless subwoofer for stronger low‑frequency impact compared to the Bar 300MK2’s integrated bass ports.

Disadvantages

✗Adds an extra component (subwoofer) that requires additional placement space and power outlet, unlike the Bar 300MK2’s single‑unit design.

Choose the Bar 300MK2 for a compact, all‑in‑one solution; choose the Bar 500MK2 if you need deeper bass and don’t mind an extra subwoofer.
