Siper Flexible cable

The cable of the newer ones is very flexilble, at cold temperatures, too.
It is a.big advantage in comparison to the older ones, because I don't feel it anymore.
So the comfort has become better than 5 years ago.
For me the best compact and portable headphone ever, you can enjoy the special sound for hours.
60 grams is for this sound still unbeatable - over 40 years long and I don't find a better one!


i did not receive the item, the reseller did not answer me at all when i asked why the parcel is not arriving...

Just... perfect.

Simply one of, if not THE, best headphone in terms of value for money on the market. Absolutely excellent in every way. Perfectly balanced and authentic sound, lightweight, foldable, and all the drawbacks of the old Porta Pro have been fixed: the headphone no longer pull your hair, the cable is flat so it doesn't break, and the sound quality is still top-notch. In short, everything is extremely well thought out. I also really appreciate the slightly retro look with this translucent design that adds to its charm. I highly recommend it to anyone who is hesitating. You can go for it with your eyes closed !

Good price for not so good plastic (As opposed to classic/headset Porta Pro)

- Porta Pros (They scream earlier Sony walkman headphones era)
- Good sound profile (If you like bass heavy - these cans are for you, although might seem muddy on lower ends)
- Comfortable (Most people say that they pinch hair, but I haven't had a haircut for atleast a year and they never bit their owner ever since I bought them)
- Good value on Black Friday (Cop those and you will not regret paying half the price of initial 50 dollars)
- Lifetime Warranty (No matter the day and age - you are covered. The reason for its usage will be explained further in cons)
- Weaker plastic (These bad boys were utilized by me on a daily basis and we had a fun journey until today, I've owned this particular pair for atleast 6 months now and their left ear plastic piece broke off, which all happened while I was taking them off.. As careful as I tried to be with them - this one particular movement was just a finished to their hardware. My other pair of Porta Pro Communication had no such issues.)

All in all - you get the signature Porta Pro's sound, have an ability to switch cables (For an additional price, however) and have a funky color scheme going on (Left - Blue, Right - Red, semi-transparent plastic chassis) - all of which make these Porta Pro stand out. But be aware - these seem to be more stiff when it comes to the headband's expansion and arms/legs folding (Which may result to same situation as I got going on in pictures, but mine broke after I took them off my head, never folded them in order to preserve them). My verdict - get a 3.5 to Type-C/Lightning and enjoy the music you love with no additional price for cables or returns.
