    The Apple AirPods Max arrived in excellent condition, exactly as described in the listing (no ear muffs). Quality of the headset itself is outstanding with no noticeable flaws beyond the stated condition, and the value at this price point is unmatched. Packaging was very secure and very protective. Shipping was prompt with next-day. Appearance is sleek and consistent with photos—overall a great transaction, highly recommend seller!

    Basic, but good quality amplifier

    This thing is a lot better than the numbers on the back would suggest. Used with 8-ohm speakers, and it delivers more power than I could possibly need. Kind of wish it had separate dials for bass and treble, but it’s not a big deal. The tone dial works well enough.

    If it's not new, it sure looks new.

    If it's not new, it looks like new. Basic amp I hooked up to a tuner.
