Relative to the Q10, there are some pros and cons. Generally I like the Q10 better, but the Q20 is much more comfortable for extended wear and has the noise cancelling feature.Q20 cons:- Has a plastic-y smell out of the package that still hasn't dissipated over a week of airing and regular usage.- The over-ear bits don't have a lot of resistance. When they move, it makes a kind of clicky plastic-on-plastic noise. Kind of worried about long-term durability.- Not a ton of horizontal grip strength, may slide off your ears. It's nice that they can rotate to lay flat against my chest if I wear them around my neck, but they still choke me, so it's not super convenient.- NC activates any time you turn it on. I'm not super interested in using the NC all the time. I wish it would stay off until I chose to turn it on.- The NC feature has an indicator light, but there's no light to tell you if the device itself is on or off. I tend to forget to turn off my headphones, so the indicator on the Q10 would let me know at a glance whether it was still on or not. Without a light on the Q20, I frequently forget it's on, which leads to battery drain and confusion about why audio isn't playing out of my computer speakers.- Likewise wish that the power button were on the same side as the charging port so I can see when it's done charging.- If you up the volume on your device to 100 while playing audio, the headphones play a tone. I get that this is supposed to be a helpful indicator, but it completely undercuts whatever I'm listening to.- A lot of people complain about the Q10's bass being too powerful, but I loved that. In comparison, the Q20 is much tamer and has a less powerful bass, even with the bass up feature.- Will not let you adjust volume settings if no audio is playing.- The manual it comes with is one of those ones without words on it. I really dislike having to decode the symbols for different kinds of button presses and features.- Q10 had a better battery life.Q20 pros:- Unlike the sweaty, stifling Q10 ear pads, the Q20 is breathable, even after multiple hours of wear. Super comfortable in general, too--the padding along the headband part is nice and cushy.- Noise cancelling works alright for the price. It's not super powerful, but it does something.- I like that the Q10 has the power button on a different side that the volume control, because I accidentally hit is less often.- NC can be used in wired mode. Also love that there's a wired mode that works without battery.- Intuitive button programming, buttons are easy to feel.- Like the Q20, there are voiced cues to let you know the device is turning on and off, what the battery level is, and whether you've turned any features on or off (bass up, NC).- Good sound quality, suits my needs just fine (casual music, videos, games, and general listening).

The bulbs are a strong white light, which is totally perfect for some people! Still looking for a softer replacement bulb

I was worried about the bad reviews i read because some people got the kit incomplete, another ones broken. I received this kit the day before i was leaving to a roasdtrip and it was the best thing i bought for my trip, the stick is such amazing, all the mounts, and everything is like new!! in a very good condition, and the price is awesomeeeee, BUY THIS KIT GUYS!

I was blown away from the quality. I use this for my phone and I love it, really sturdy. Definitely a great buy!

I like the motions light detectors. I use it for the closet.

I love this so much it was so easy to use and i love how portable it is. having this had made transferring my pictures so much easier and they transfer so clean i love it so much and would definitely recommend buying

I count tell if it shut off. The buttons were not easy to find.

Device is comfortable, easy to use and convenient for travel.I have a friend that has sleep apnea and he recommended I get one.WOW, I had dips of O2 down to 80%! I ran to the Dr. and I'm now using a CPAP. Incredible the difference, now I'm consistently over 96%.I wear it every night to make sure my treatment is working.I have recommended the sensor to friends, so far one had a similar discovery, and is going to the Dr.
