The only difference between our plug refurbished Airpods 4th Gen and a brand new one is the price. Our Airpods 4th Gen are up to 40% more affordable and are backed by our plug 1-year warranty. To ensure our products meet our incredibly high-performance standards, we’ve developed a proprietary 90+ point functionality evaluation, deep cleaning, and sanitization process. Specialized technicians at our company’s headquarters hand test each device, and only products that pass our rigorous testing receive plug’s Certified Pre-Owned status and are sold.
