when my headphones arrived, I ran into some setup trouble: I could only pair one side with Bluetooth, and the green and earpads shown in the listing weren’t included—just black and orange.I contacted customer service, and they responded within 12 hours, which was great. They explained that to pair both sides, you need to press both power buttons at the same time. Also, each side charges independently, and the included charging cable is wide enough to charge both at once. After resetting, “forgetting” the headphones from my Bluetooth devices, and pressing both buttons as instructed, the headphones paired together and now work perfectly.The vendor also promised to send the missing green and blue earpads.Once those arrive, I’ll consider updating my rating.-- The corrected ear covers in a dark, green arrived 4 days later.... Perfect...Overall, the initial setup was confusing, but the responsive and knowledgeable customer support made up for it. If you’re having trouble pairing both sides, just press both buttons together and reset your Bluetooth connection.-- In business its how a company handles a problem that separates good from great...Great Company !

Very comfortable ear cushion (orange and black included). Good quality of bass and very nicely equalized sound.

The media could not be loaded. I bought this because it is a Porta Pro clone which I have never seen before. If compared to the actual Porta Pro Wireless 2.0, it is better than the original in many ways. It appears to be better constructed, it comes in multiple colors, sounds better and is louder and it comes with two extra pairs of ear pads! These headphones—unlike the Porta Pro 2.0s are true wireless headphones. The charger comes with two connectors as you charge the ear cups separately. The Porta Pro 2.0s have the two earcups connected via the headband. For $69, this is an excellent deal! The sound quality is excellent and it actually has a button on each ear cup. Click the right or left one to pause or play music, click the left button twice to decrease the volume and click the right button twice to increase the volume. Hold the right button to go forward a track and hold the left button to go back a track. The only thing missing is Siri control which the Porta Pros whether they are 1.0 or 2.0 can do. These things are great and I highly recommend. Also the seller is great. My first pair was disconnecting the ear cups from each other. I returned it and got a replacement one which works great. The other negative is the fact that the battery life is not the 18 hours promised. I am gonna say it is closer to 11 or 12 hours.

The media could not be loaded. As someone who has collected over 20 IEMs and open-backed headphones ranging from $15 to $250, these have surprised me. I have always been interested in these retro koss style headphones, but never pulled the trigger until now favoring other budget IEMs. The last time I tried a headphone with this style was before my first iPod with my portable Sony CD player. If you are judging these purely on price-to-performance sound quality, you will be disappointed. You can do better with a set of Truthear REDs. That being said, you don't always want an in-ear (especially one as large as the REDs). These are an extremely portable over-ear headphones that is surprisingly comfortable. The tuning is nice and enjoyable, and doesn't distort my music with an uncomfortable tone. I would say the set is not the clearest headphone, but it is not bad. The bass is capable, but like most open-backs, it won't compete against an isolated closed-back or IEM.I will mention that my iPhone with the US Apple dongle had to have the volume quite high for a comfortable listening experience. I did not have that issue on any of my other DACs or my Steam Deck, but I thought I should mention it. You may find the volume lacking if you are using the less powerful EU Apple dongle. Speaking of the Steam Deck, that has become my favorite use of these headphones. Sometimes I tire of using IEMs, and the sheer portability of this set makes it perfect for on-the-go gaming. The headset easily rolls into a small puck-like shape and can fit into most bags. The weight of the set is barely an inconvenience. I can easily fit this in the same travel case as my Edition XS headphones. I have included a video of me rolling and unrolling the set to better visualize the experience. In terms of the build quality, I am very happy. The included MMCX cable is simply delightful. its as flexible as a shoelace and has next to no memory. I chose the MMCX version so I could easily replace the cable, but I don't think I will unless I can find a 4.4 balanced cable. None of the metal is sharp, which is great as that would instantly ruin this headphone, considering how often you have to adjust the headband's size. In terms of aesthetics, these are a lot of fun. My set came with a green, black, and orange set of pads. I would have liked to see one of the sets of pads to include the center cutout for a different tuning experience, but that is an easy modification. As it stands, the pads are purely aesthetic. The overall design is striking, if not very reminiscent of Koss's offerings.I don't own any koss headphones to pair these against, but on their own, these are quite nice as long as you understand the limitations in performance this type of design is capable of reproducing. For what they are, I enjoy them and will continue to use them in my headphone rotation for their unique experience and portability.

Obsessed with these retro headphones! The classic look is timeless, and the soft padding provides all-day comfort. They connect seamlessly via Bluetooth, and the battery life is impressive. A must-have for anyone who loves a touch of nostalgia.
