66 Audio BTS Pro vs Samsung Gear IconX

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.

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.

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.

Bluetooth connectivity allows the BTS Pro to connect with smartphones and compatible music players wirelessly, so cables won't be an issue.

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.

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.

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.

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.

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.

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.

The highs and mids are not amazing, but they most certainly sound good with nice clarity and warmth. The bass is very good. There is a lot of low-end presence with good thump. These will most certainly excel with bass heavy music and are great choices for working out, as the thump will definitely help you stay upbeat.

The Gear IconX has 4GB of internal memory where you can store files like music and play them from just the earbuds.

There is a built in heart rate monitor and you can set these earbuds to tell you exercise-related metrics at set intervals. Also, you can sync the IconX to Samsung's S Health app where you can view fitness metrics.

Once synced with your smart device, you can set which of the earpieces is the primary device. You can do gesture controls on it to control your playlist as well as answer or end calls.

These come with ear tips in three different sizes for you to get a nice and comfortable seal, as well as 3 wing tips in various sizes which adjust how snug these earbuds can be.

A nano-coating is applied to the ear pieces, preventing sweat and splashes of liquid from causing damage.
