I would recommend the headphones if they cost no more than half the price I paid.
Good stamina.
I hardly notice them on my ear, sometimes I look for the earpiece and have it on. There is no problem with them in steeper movements.
I would describe the sound as "ok", I'm no expert but I could rate it as not great either way. They are fine for normal everyday activities. I listen to the word, to music, to the phone.
I've never seen a box that big before.
Sometimes I go to get a charged handset and it is not charged, the grip of the headphones inside the charging box is not ideal, sometimes the contacts do not meet (it wants to be more careful when storing the handset, however, I am still used to the magnetic attachment, which slides the handset where it needs to be, here you need to be careful personally: -).
Outside the charging box there are LEDs that indicate the state of charge (of the box), they light up "like crazy" (at night it is quite visible), however, I often do not notice that the box is discharged. I guess I'm used to - from cheaper models, surprisingly - that the display directly shows me the charge level.
In noisier environments, e.g. walking down the street next to a tram, you can't amplify the sound to a level that would overpower the tram etc, I just can't hear what people are saying to me in my headphones, at higher ambient noise levels I hear the ambient noise, not the sound from the headphones.

Product purchased as "unpacked goods", but nobody at Alza seems to have bothered to check full functionality. Charging problems from the start - the left handset discharges quickly and heats up uncontrollably when charging. The charging box does not go out when fully charged, the LEDs light up and the box discharges spontaneously. I will return the item within 14 days and try to pay extra for a new piece.
Good sound
Fits behind the ear even when running
Left handset discharges and overheats quickly
The charging box discharges by itself

I had an older model Intenze movie and there was GREAT satisfaction. That's why I decided to stay loyal to the brand. Unfortunately, there was a big disappointment with this product. Headphones very loose around the ears, sound like from the bottom of a well, do not stick properly to the ear, I am not satisfied with this product.
Easy.
Wireless.
Looser behind the ear
They fit around the ears rather than in the ears and very loosely.
The sound is reminiscent of the headphones from the nineties, which were brought here from Poland together with wolkmen
Very soft material that "holds" the headphones behind the ear.

For me, totally awesome I don't need any others
Super hold during sports
Waterproof (against sweat)
Sound without a problem
(maybe not a minus) can only be connected to one device at a time, but I don't know if it's even possible to do otherwise

the handle behind the ear threatens to burst

They are perfect for my needs.
Both parties can hear well during the call
Great for podcasts
Seamless automatic connection to the phone when removed from the case
Seamless pairing with each other
They also work individually, the second one is charging in the case in the meantime
I like the squish button instead of the touch button, works well. I've already learned the grip to squeeze it so the earpiece doesn't dig deep into my ear: )
Holds me well for manual work and cleaning
Bluetooth has sufficient range
Do not print
I wear dioptric glasses with thin legs and don't mind the headphones
Not for listening to music for me, but I bought them for calls and podcasts and they are perfect for that
On smaller ears they might not hold up
A little bit of noise when listening, but it doesn't bother me significantly, but it would be disturbing when listening to music

Hello, thank you for your review, on the basis of which the manufacturer contacted us and would like to comment below.
"We're glad you're happy with the headphones. The priority of these headphones is just the perfect ergonomics, to keep the headphones firmly in place and at the same time to be comfortable for everyone thanks to the flexible silicone hooks. The silicone hooks can be removed from the headphones and you can only use the headphones themselves without the ear hooks. Different sizes of earpieces are also included for comfort and bass boost. If your headphones are buzzing, try resetting your headphones:
1. On your phone, remove the headset from the list of paired Bluetooth devices and turn off Bluetooth. 2. Switch on both handsets and in pairing mode, press the button on the left or right handset 5 times quickly. 3. You can turn on the Bluetooth function and you can pair them with your phone again. If the problem persists, it may be a defective piece. In this case, you can

I ordered the headphones after my JBL Live PRO TWS 2 headphones fell out 2 times while skating. I really don't want to lose a headphone for 3000 that, from my point of view, sounds, dampens and handles uncompromisingly, but just doesn't quite stick like nailed. That's why I was looking for headphones with better fixation on sports. Coincidentally, I met a neighbor who was returning from a run, she showed me these headphones, so I immediately ordered them and picked them up from Alzabox a few hours later. The headphones don't sound completely crappy, but the quality of reproduction we are used to is not. But they also cost a lot less than the headphones I usually buy. So far, the headphones seem to fit on the ears really reliably and, most importantly, they mate seamlessly with the Garmin watch. Which is certainly not the rule. They don't have ANC, which for my use when I need to perceive my surroundings is not a bad thing at all. I don't dare to evaluate the button control instead of touch yet. It takes quite a lot of force to press the button, on the other hand, when I sweat, sometimes the touch does the opposite mischief.
It really fits the ears. I've tried bouncing them and the fixation mechanism is really reliable. The headphones fully fulfill their purpose for which I bought them - good fixation during sports activities.
They work correctly with Garmin watches, which is definitely not the norm with headphones. This is one of the conditions for skate headphones. I only ride with my watch, never with my phone.
The sound is average. It's not a disaster, but you can buy much better sounding headphones at this price. However, they do not have a fall arrest device. I'm such a headphone collector and I bought these headphones simply because I don't want to go back 50 meters and look for a headphone on the ground that fell out while skating.
It doesn't have ANC, which again is not a disadvantage for me - I won't be using these headphones in the gym, where I need the ANC to block out the gym music, but out skating, where I'm only using one headphone anyway due to the need to perceive the surroundings.
