Pros
Pro Good battery life
You can get around 8 to 10 hours of use from a full charge.
Pro Earphones stay in place well
The earpieces won’t easily fall from your ears when using these on the go. You get Bose’s StayHear+ wing tips which securely fit inside the ears. Also, since the noise cancelling electronics are in the collar instead of an inline module, there is not a lot of weight that pulls down on the earpieces.
Pro Very good noise cancelling
While the noise cancelling does not eliminate all of the ambient noise, it does a good job of preventing most of it from mixing in with your music. With the audio turned up to a good volume, you aren’t likely to hear your surroundings except for the loudest of sounds.
Pro Adjustable noise cancelling
You can dial in the level of noise-cancelling that you want using the Bose Connect app which is available for Android and iOS. This gives you more flexibility with active noise cancelling compared to other earphones.
Pro Full sound with good detail
The bass of the Quiet Control 30 sounds full, with good punch and power. It doesn’t add any bloat though, preventing the sound from getting too muddy. The mids are quite forward with a slight boost. Vocals and guitars can easily be appreciated, though heavy guitars may sound quite aggressive due to the slight elevation. The highs are clear and offer a good level of detail yet do not get harsh in any way. These earphones are good for general music listening, and should excel in vocal-heavy tracks.
Pro Detailed sound
The CXC700’s sound signature puts emphasis on the treble. It is very airy and detailed, so you’ll be able to hear the nuances of the music. The bass is controlled rather than boomy. The mids are slightly recessed though, so vocals and guitars are not up-front.
Pro Talk Through Mode allows easy conversations
You won’t need to take these headphones off when in a conversation. Activating Talk Through mode on the noise cancelling module allows the microphones to pick up ambient sound and output them through the earpieces, so you’ll easily hear what others are saying. When you are done conversing, simply press the button again to enjoy your music.
Pro 3 active noise cancelling modes to choose from
You’ll be able to fine tune how effective the ANC can be in your environment. There is a mode that focuses on the low frequencies, another that also filters out the mids and the third mode covers the entire frequency spectrum.
Cons
Con There is no way to secure the earpieces when not in use
The earpieces will dangle off of the collar and flop around when they are out of your ears. There are no magnets in the ear pieces to keep them together, and there are no fasteners or docks in the collar to secure the earpieces. Other collar style earphones have this feature.
Con Bluetooth only
You won’t be able to continue using the QuietControl30 when the battery runs out. You only get Bluetooth connectivity, with no wired option, so you’ll have to charge these earphones in order to use them again.
Con Control module is bulky
The noise cancelling module can be distracting. It is quite large and heavy, and may pull the headphones down. There is a belt-clip integrated into the design, which may help minimize the issue.
Con The audio may sound lean
If you prefer a rich and powerful sound, then these may not be to your liking. The bass does not have a lot of thump and the mids are recessed, so the sound may seem thin for your tastes.
