Besch..eidener mono sound

Summary: "professional," mechanically comparatively high-quality headset with a proprietary connection and outrageously expensive adapters. Maybe (!) Acceptable to call centers and the like, only limited use of the smartphone and not recommended.

Unfortunately, I fell for Sennheiser escapist Marketing poetry. "Breathtaking look. Stunning sound. An outstanding audio experience. Stereo for maximum focus" etc.pp ..

But there is, unfortunately, quite a bit of poetic license taken into account. Outstanding listening experience? Well: no bass and subjectively un-brilliant heights. The fall in call centers probably not particularly on, as long as you only phone with it, but listening to music brings no fun. However Fittingly, Sennheiser, as the frequency range of the SC 660 only modest 50 Hz - 18,000 Hz indicating unlike Sennheiser hi-fi headphones that can reproduce below 20 Hz to about 20,000 Hz to.

Listen to music with the SC 660 the way also, therefore, is not really, because the headset the sound in mono only reproduces. I mean, the left and right you can hear basically the same. This can not be otherwise, because on closer examination it turns out that the four-pin connector of the SC 660 with Microphone (+) / headphones (-) / headphones (+) / Microphone (-) is occupied. For stereo operation absent any conditions, because your left and right depend on the same line. (We remember, undeterred writes Sennheiser: "stereo for maximum focus".)

The four-pin connector of the SC 660 is realized by an "Easy Disconnect" baptized plug hard plastic, which is available only at Sennheiser. You can see it on the product photo to the right of the headset. These "Easy Disconnect" connectors are an estimated 25 mm wide, 40 mm long and 5 mm high. It is installed a button, through the actuation of a possibly existing plug-in is really catapult-like separated. The re-plugging is considerably fummeliger, you need a much better eye-hand coordination than other connections. The plastic plug acts also fragile. I would bet that is immediately broken when he gets under the wheels of an office chair only 1 time. I have not tried it dear.

Because there are these connections only from or at Sennheiser, one must therefore inevitably still have another Sennheiser products, where you can plug in the SC 660. This can be for example an adapter cable.

For the BlackBerry Z10 you can buy here the adapter 502 729 (GSM-ADP-CBB01) Amazon from 38 euros. This adapter connects a "Easy Disconnect" connectors with a four-pole 3.5mm jack, headphones (-) and microphone (-) of Sennheiser are here against shorted together, the right channel of the smartphone is connected to nothing at all, and supplies the left channel both earcups. To answer a call, you have to take the phone in hand, a hook button does not exist.

Available directly from Sennheiser is the adapter 09907 (CEDPC 1) which connects an "Easy Disconnect" connectors with two three-pole 3.5mm jacks, one for microphone and one for earphone for 35,70 Euro. At the three-pole 3.5mm plugs each tip is shorted to the ring, because everything is mono. Not all recording devices to work with such assignment, my Sony PCM-D50 for example, takes nothing from the microphone on the SC 660. Useful This adapter still be to implement the proprietary "Easy Disconnect" link on standard connectors to which you can then connect additional, possibly selbstgelötete adapter.

Conclusion: Clean mechanically the headset looks not so bad, except the ME creepy plastic construction called "Easy Disconnect". When the headset would be a stereo feature and reasonably acceptable (read: not tinny so) would sound, then I would consider whether I should not just cut the "Easy Disconnect" connectors, and in addition to a call answering button and a reasonable XLR connector off tinker, who also an office chair role would survive. But as I have sent back the part.
