Review on EPOS SENNHEISER Adapt 660 1000200 by David Hashman

I use the headphones during the working day and mainly for conference calls, listening to music and sometimes streaming shows. My requirements for headphones are: 1) Microphone quality and noise isolation so that others can hear me well 2) Bluetooth adapter for better connection with PC 3) Connect to more than one device via Bluetooth at the same time 4) Wear comfortably for 5 to 8 hours in one piece. I already know that only in-ear or in-ear headphones are enough for me for longer periods of use. I've been using the EPOS Adapt 660 for about a month now and I love it. a few pros and cons: Pros: - Comfortable for hours. ears are not hot. On the other hand, I'm mostly indoors and it's not summer yet. As I have a large head, while still reasonably comfortable, I would have liked the headband to be able to stretch out a bit if possible. never mind I don't usually need noise canceling as I'm usually indoors and the over-ear design is already enough for me to block out outside noise. I tried it with a vacuum cleaner working nearby and in this case the ANC function works well. The quality of the microphone is good. From time to time I have to adjust the position of the headphones on my head to get clearer mic reception (according to people on the other end of the line). This is how I position the headphones, i.e. the directional microphone, so I cannot fault the product - I am satisfied with the sound quality. Better than my old Plantronics Voyager UC. But I'm not a music lover - the construction is quite solid. The connection between the earcups and the headband is metallic and strong. Headphones are relatively light. Headphones are not too big, unlike some other models. Cons: - Team button doesn't work for me. I set it up with the PC software and the button still doesn't do anything. I've tried changing it between Skype and Team but still nothing. I want it to work, but it's not that critical to me. I'm used to the Voyager UC Focus, which originally didn't have such a button. - After 8 hours of calls and music, the battery says more than 40% left. Enough for me but seems less than advertised. But I haven't tried draining the battery to be sure. The remaining battery reports are different for the headphones and the mobile app. I'm not sure who to believe. For example, right at this moment my 660 reports "more than 60% available" when the iOS app reports "100%" of available battery. Also, the 660 reports "more than 80% available" even after I charged the 660 overnight. I couldn't get the 660 to report "100%". I think technically 100% is "more than 80%" - I'd like to have more options for changing the treble, bass, mid, etc, not just the Theater, Voice, etc presets. option is not sufficient. In general, I like higher frequencies and leave the rest normal. I don't have that option here. No showstopper. I may be dated, but I would have preferred a physical on/off switch rather than a 90 degree headphone twister. If I temporarily wear the headphones around my neck, I have to straighten them out so they fit snugly - this disables the headphones. When I turn it back on, I have to wait a second for it to reconnect. USB-C would be nice for charging. Here is some information about my preferred trip before I decided on the EPOS Adapt 660. I used the Platornic Voyager. UC Focus used to be, but it's outdated and had mic issues after two years. Before stopping I looked at Bose 700, Bose QC35 II, Jabra Evolve2 85, Jabra Evolve2 65 and some others. Prefer retractable. But mic test videos from various reviews convinced me that the Bose 700, EPOS 660 and Evolve2 85 have enough directional mics to work well enough. The Evolve2 85 looks promising and the sound test seems to be good, especially with the boom mic extended. However, my concern is that the boom mic looks a bit flimsy. Might break more easily. Also, the earbud feels quite large on my relatively large head. Not to mention the price. I have a similar boom mic issue for the Evolve2 65. If I were considering the Evolve2 65 I would probably go back to the Voyager UC Focus as it's robust and both are on the go. ear design. QC35II is an older model but has received many good reviews. However, the microphone appears to be absent, as are many complaints of overheating. Most importantly, Bose doesn't have a USB dongle (at least it doesn't come with it and it's expensive to buy separately). So I narrowed it down to 660, Bose 700 with optional USB dongle, Evolve2 85 or (again) Platonic Voyager UC Focus. I chose the EPOS Adapt 660 primarily for the balance of features and price. Hope that helps.
