Specs
Ranked in these QuestionsQuestion Ranking
Pros
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.
Pro Water resistant
The IPX7 certification means these can work even when used while swimming. Do note however that increased water pressure (like when diving) can still cause damage.
Pro Powerful bass with smooth mids and highs
The highs and mids have good detail but are not forward or boosted. Instead, they have a smooth quality to them that makes them easy to listen to. Bass quantity is pretty high, and with good power too.
Pro Can play music off of internal memory
The Dash features 4GB of internal memory. This allows the earbuds themselves to hold up to 1000 songs, which can be played without connecting to a music player or smart phone.
Pro Earpieces are touch senstive
Users can make taps or swipes on the Bragi Dash's touch-sensitive areas on the earpieces. This can help to play or pause music, skip current track or play previous track, control volume as well as other functionality.
Pro Can connect to Bragi's fitness app
With these earbuds synced with the Bragi companion app, users can track fitness-related stats like heart rate, distance traveled and the like.
Cons
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.
Con Mic quality is quite poor
The sound coming from the bone-conduction microphone is not very good. It sounds tinny and cuts off every now and then.
Con Bluetooth signal is not very stable
Music and calls can get choppy on a regular basis. This is more prevalent when there are other wireless devices in use within your vicinity.
