Pros
Pro Ample padding on the ear pads make these comfortable to use
Both the ear pads and headband have a good amount of foam in them, which results in adequate cushioning. They're quite comfortable even if you've been using them for several hours straight.
Pro Good detail on the highs and mids
The sound is fairly balanced and can work well with most music genres. The highs and mids have good presence. Although they are not that clear, there is still an acceptable level of detail to them. The bass is not impactful but it does have some depth and helps give a fuller feel to the overall sound signature.
Pro Lightweight
These are actually pretty light weight for over the ear headphones. The HD 201 will not cause unnecessary strain to your neck, even if worn continuously for extended periods.
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 Does not effectively block outside noise
Despite the closed back design, there is still a fair amount of noise that can mix with the music . This can have a negative impact to your listening experience, especially when you are in a noisy environment.
Con Build quality feels flimsy
The HD 201 has a lot of flex and also tends to make rattling noises when held or moved. This can be attributed to the cheap plastic used in the build.
Con Can get warm around the ears and on the head
The synthetic leather on the ear pads and head band prevents airflow around the ears. This causes warmth to build-up quickly.
Con Very long, non-removable cable
The cable also easily tangles and can make the headphones difficult to store/organize.
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.
