The humming:
I just now dealt in detail right so via forums and services, and come to the following conclusion:
It is a matter of luck, if you caught an audible whirring glasses or not. I am unfortunately the less fortunate, both my eyeglasses whir clearly on the left bracket. It is admittedly not permanently be heard, with appropriate sound setting, it does not fall more to continue. In quiet passages, however, it is hard to ignore and very annoying. People who (more) can not capture the upper frequency range, so exquisitely older semester, it could not perceive my experience.
The Service:
Did I only approached the shop, who then referred me to MC & S, Optoma service center in Germany. Glasses sent over and just get back, with the note that no deficiencies were found and the spectacles comply with the specifications. The wanted me also the responsible employee whiten on the phone, I have called for it. A slight hum is normal in the glasses.
If ye lest ye but soon realize that it is very probably are differences and that there are many people who absolutely hear while wearing the goggles NOTHING through the forums. That these are subjective impressions, I do not think. Finally, some report that they have been tested already buzzing and whirring not glasses.
The Processing:
Here probably lies the main problem. Those things make a fairly cheap and crappy impression a simple, low-grade plastic construction. The inside seems therefore probably get similar stümperisch, which leads indeed to the described variations in quality. The operation, which is the power button, is an impertinence: pressure and depth stop is scarce but a certain amount of force, it is still required, what you actually do not want to expect the rickety ironing. Thus, the switching on every time is quite a hassle. For me, serving the things regularly, that's basically not so tragic. "Newcomers" but so rarely get along, so I simply always miterledige the same for them. Sure, there are worse things. But a button, the exercise requires what are you doing?
The Price:
The main reason for my poor rating. The spectacle is not just bad, I do not want to say yes. And I also know that it is even more settled even in the lower price segment. Creeps me only a strong suspicion that an attempt is made here to do with supposed high earners by fantasy prices Checkout. Anyone buying a 3D projector, can not avoid the purchase of eyeglasses and money it can bring you also do not come short, so probably the simple formula of the manufacturer. Therefore, in my view not only 3D glasses deserves more than two stars. I can tell no one that this rickety parts cost more than 5 in the production. Because of this audacity I pull from three star and the fourth because the described shortcomings. The one star is in my view therefore more than justified.
