We use the low-ohmic variant SC 662 in conjunction with the USB connector UUSB-8 and the 3.5 stereo adapter for use on the go.
Sound / Ultra Noise Cancelling:
Microphone:
For us, the noise suppression was one of the decisive purchase criteria.
This is achieved by the SC 660 perfectly.
Example of use:
Skype conversation in a cafe: two elderly ladies lead a more intense conversation at the next table. At the table on the other side a customer maintains via video conference with a colleague.
From the ceiling speakers comes semi-loud music.
For me as a guest disturbing.
For our customers: Absolutely perfect.
You really only hear my voice.
On demand, is specified to be able to hear very quiet with exact concentration in the background.
That's -unserer opinion downstream impressive.
Application Example 2:
At 150 km / h in the Skoda Octavia on the highway. (Used by the passenger!).
1) Directly via iPhone 5. Then with the Sennheiser.
to 1) Interlocutors interfere with the loud engine noise, the wind noise.
Frequent inquiries.
to 2) The interlocutors ask for, where we are. No (or only at a closer focus on) wind or engine noise.
Whether we the customers now perfect or less than perfect hearing as "service providers", was secondary for us: It was important that the customer who thus "paid" us, can perfectly understand us.
For this 6 star.
We understand that customers are always very good - but since the SC 66x does not offer active noise cancellation headphones for, little -but always ausreichend- of the ambient noise dampened.
A sound example we try nachzuliefern.
Comfort:
This will depend on your head size and the personal preferences. The adjustment is extremely stable and durable. The grid is labeled - so you can just put on 4.5 - and does not have to play around a long time.
We like to wear - but it naturally prefer to run without headphones through life.
Processing:
Yes - it really is a successful device. The clack noise when rotating the earcups: saturated.
The adapter act -zugegebenermaßen- not like that they would survive hover once by car. But we see no problems here.
Price:
For us not the most important criterion. Have satisfied customers - rather invest more.
The price-performance ratio, we find reasonable.
Summary:
We are happy every time we can use it.
The perceived quality, the feel, the processing of the pivots.
Everything seems all of a piece, durable and "Made in Germany".
We would buy it again at any time. 6 stars from us.
Suggestions for improvement:
Anti-Noise for the headphones (but batteries would be needed).
