Pros
Pro Reference quality sound which can be fun to listen to
Sound signature is fairly neutral, with slight elevations to the bass, mids and highs.
Bass has a nice fullness to it, with some extra depth which gives the sound a lot of body.
The mids are neutral but slightly forward, making the vocals sound really clear. Aggressive guitars can sound a bit harsh because of this though.
Treble has good extension, and the added peak on the highest frequencies add more sparkle to the sound.
Overall, these headphones can be used both for critical listening and for casual music enjoyment as well.
Pro Superb sound isolation
The closed back, over the ear design blocks out a significant amount of noise, allowing users to easily focus on the audio. Sound leak is also kept to a minimum.
These are great for tracking and monitoring, and are also great choices for use in quiet environments like a library.
Pro Headphone cable is detachable
You can easily remove the cable when these are not in use, making them easy to store. This also makes the cable easy to replace when needed.
Pro Great for use when outdoors, going for a run or working out
The BTS Pro is quite robust and can withstand some minor splashes of sweat or rain as these are sweat-proof. They are not completely water-proof though, so you should not get them soaking wet.
Pro Good sound quality with focus on the lower frequencies
There is good detail in the highs and the mids can also be heard clearly with very little muddiness. The lower frequencies are boosted, resulting in a good level of depth and power to each bass thump.
Pro Will stay snug on your head
The BTS Pro ear cups sit on the ears with hooks keeping them in place. The flexible connecting band provides good clamping force and can adjust to your head size with continued use. Combined with cushioning on the cups, these are comfortable to wear and will stay in place.
Pro No long cables to deal with
Bluetooth connectivity allows the BTS Pro to connect with smartphones and compatible music players wirelessly, so cables won't be an issue.
Pro Companion iOS app adds extra functionality
66 Audio's Motion Control iOS App gives users added functionality, including EQ control and presets selection, battery status indicator, and even headphone position tracking. These features can improve the listening experience and also minimize the chances of you losing these headphones.
Pro Can last through multiple long listening sessions
With up to 40 hours of playback time at full charge, it's more than enough for most listening sessions. You won't have to charge these frequently.
Pro Hardshell case makes transport more secure and convenient
A hard shell carrying case is included, which can protect the headphones from minor impact and also make transport much easier. The case also has good aesthetics.
Pro Can be folded to a more compact size
They are easy to bring on the go as the ear cups can be folded into the headband. This further reduces the already slim and compact size, making them easy to chuck into a bag when on the go.
Pro Ear cup functions as a remote
The right ear cup of the BTS Pro features buttons for controlling headphone features. You can play/pause tracks, increase/decrease volume as well as answer/end calls by pressing the corresponding buttons, negating the need to pull out your phone to do so.
Pro Allows taking calls
You do not need to take the BTS Pro off in order to answer incoming calls. There is a built-in microphone which allows you to easily take or make calls in the middle of your run or workout.
Cons
Con Build quality is rather poor
The overall build is quite plasticky, with a lot of rattles. While it is not fragile by any means, the build quality certainly does not inspire confidence.
Con Ear pads are not the most comfortable
Pleather is used on the surface of the ear pads which traps heat and can make the area around the ears warm up fast. Also, while the ear pads are large and soft, they are also quite thin. People with larger ears may experience their ears rubbing against the driver housing, which can get quite uncomfortable.
Con Thin headband padding
There is minimal cushioning on the headband, so the plastic may dig into your head when using the headphones for long periods.
Con Some distortion can be heard at lower volumes
There may be audible levels of a scratching sound or distortion when using these at lower volume levels. This can be quite distracting, and can have a negative impact on your listening experience.
Con Motion Control App is for iOS only
At the moment, users of non-iOS devices will not be able to take advantage of the companion app's functionality. However, 66 Audio have announced that an Android app is currently in development.
