Dotazione di accessori estremamente completa, audio sempre chiaro, velocissimo nel collegamento con il device.
Unica pecca, l'avrei preferito un pò più comodo da indossare. I gommini sono duri e l'archetto è un pò troppo rigido per i miei gusti, in assenza di questo (lo uso così) spesso può cadere dall'orecchio.

My period headsets include Jawbone era, jawbone new era, Plantronics voyager legend, edge, Conger, voyages pro, Bose series 2, h730,h710, Motorola whisper, blue parrot(big one for truckers), and many many more. My criteria: comfort, sound quality, sound quality for the person on the other end, noise cancelling (very important to me), appearance.
This is the best one I've ever tested. The noise cancellation is unreal and exceeds the decibel rating of all others except the blue parrot. It is near exactly the same as the blue parrot. However, the blue parrot looks totally ridiculous around town!. This has a slick sliding mechanism for easy turning off and on. It fits the ear gels still sold on Amazon which ensure that it's comfortable and stays in your ear. It comes with a nice spring loaded hard case, high quality ear hook, car charger and a short micro usb that fits in the case. It also has a nano dongle for computer listening, which is handy.
This is a keeper for me, and will be for you!
Update: 7/1/17: So, I've had this for 2 years and 3 months. I have used it a lot. Of course, i sometimes use the Motorola whisper or the Plantronics Focus (when I want to listen to music and have great noise cancelling), or the Plantronics Voyager 5200 (for extreme all-day comfort)... However, I still come back to using this headset because it works great, I like the slide on and off feature, and it looks good. It still works like a champ. I have NEVER had a bluetooth work flawlessly for this long before. EVER. My plantronics, while half its age, start acting glitchy and disconnecting or doing annoying things. This one, however, still runs like new. If you're like most, normal people and you just need one bluetooth headset, this is a solid, reliable purchase, in my experience. The case has held strong and has been tossed into bags, sat on, etc over the years. The noise-cancelling is still best-in-class. In fact, it is what encouraged me to purchase the PXC550 to replace my glitchy Plantronics Focus (and has worked flawlessly as well). I'm sure there are people that had less than bright experiences, but I have to wonder if maybe they bought a used one that had ran through the washing machine or some other craziness. But, for me, I have to reiterate that I am still very happy with my purchase.
After 6 months of use I am getting constant complaints about my transmit audio quality. So much so that I can no longer use the headset. I left myself a voicemail to test this out and only 1 out 5 words were audible. (I tested this on 3 different phones - all with the same results)
Sennheiser makes three variants of this device so it is extremely important that when making the purchase, particularly off Amazon, one checks the model number as one will either end up buying a device that is more expensive than you need or one that doesn’t achieve what you need.
I bought the Microsoft Lync version – Presence UC/ ML (Sennheiser model number 504575 - Sennheiser Bluetooth Headset for Universal Devices- Retail Packaging - Black/Silver) and it works perfectly and has made attending WebEx meetings and taking Lync calls super convenient as the included dongle connects seamlessly.
Voice clarity is great even with a lot of background noise and I am on the road a lot (and I was very sceptical about this as I have used a number of noise-cancelling headsets in the past that haven’t performed as well).
The ability to connect to two devices simultaneously (two phones or a phone and a computer) was a necessary condition for buying this device as I keep one phone for work use and one for personal use.
Battery life in terms of talk time is as advertised (8-10 hours on a single charge). I am a heavy user and my work often requires me to be on the phone for about eight hours a day but I still find I can get by with a single charge overnight or, if my talk time usage has been light, a single charge after a couple of days. The average user will probably be able to get by for 3-4 days without needing a charge.
Charging is quick so on the occasion when I have needed to boost the charge, that has happened quite quickly. A full charge does seem to take a little while though.
Bluetooth range is great with one being able to wander between rooms without it affecting reception quality and the range doesn’t deteriorate appreciably even when the battery is on its last legs interestingly enough as one would expect it to.
The included carrying case is useful as the dongle is quite small and it also has a space for the charger cable (though there is no plug so one will need to either plug this into your computer’s USB port or the plug for one of your smart phones).
The form factor of the device itself is quite unobtrusive and the device is light enough that as far as weight goes, one doesn’t really feel it even over long periods of time. (This is compared to some of the comparable devices available in the market which require long booms or large over the ear portions to achieve the same usability.)
Though I have provided a different point of view with regards to the on-off mechanism below, I also find it super easy to use as compared to most devices that require one to locate and press a tiny button on the device. While on the subject, the multi-function switch on this button works perfectly.
Despite being light and appearing not as heavy-duty, I have already dropped it a couple of times, and it still works perfectly nor have any scratches or cuts appeared on the device so Sennheiser appears to have used quality materials.
About the only three minor negatives I can think of are:
(1) I find the ear loop a little uncomfortable at the point where the loop rests on the top of my ear but that might also be because I haven’t adjusted it properly and that is also after a considerable period of time. Everybody’s ears are different obviously so this is a very personal observation.
(2) As a consequence of the design of the on-off mechanism, there is a tendency for the device to get switched off when it is kept in one’s trouser or jeans pocket but on getting a call I find that I can take it out, pull the extension to switch it on and it connects within a second allowing me to take the call as I would have. I guess in a sense that could be construed as a positive since it saves on standby battery power.
(3) This device is not normally available in retail stores so one necessarily (especially internationally) has to order it on-line or through a Sennheiser dealer (and they don’t always have it in stock) so it can’t be picked up in an instant but I guess this is not an average Bluetooth device (at least the higher end versions) and so anybody wishing to buy it will not have an issue with purchasing it in this fashion.
Ultimately, what is really going to determine my opinion of this device is how long it lasts/ works. Most of the Bluetooth devices I have used in the past have failed or stop working as well after 6-8 months and I have only been using this one for about a month. The company does provide a two-year warranty though so if they stand good on that, this device will be worth the significant premium one pays for it.
Addendum: In light of the debate over whether the headset will fit right or left ears and my ability to attest to the fact that it will fit in either ear, please refer to the attached images which show the headset in a left ear and a right ear orientation with just the ear loop having to be removed and reoriented without any compromise to the fit.
