66 Audio BTS Pro vs Zagg iFrogz inTone Wireless

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.

You get a decent playback time of 5 hours from the InTone Wireless, and should be more than enough for your short runs.

You can easily control your music using the in-line remote. You can pause/play tracks, adjust volume as well as go to next or previous track. The in-line remote also has magnets, allowing you to mount the ear pieces to the remote to keep them in-place.

These earphones won’t get damaged when splashed with liquid. These have an IPx2 rating, which makes them resistant to small splashes of liquid or sweat. Getting these drenched or submerging them may still cause damage though.

The InTone Wireless delivers decent detail and okay mids. Vocals have good volume from these earphones, while you get okay levels of airiness and clarity from the treble and does not get harsh in any way. The bass is lacking though. You don’t get a lot of oomph from low-bass notes, so these are not the best earphones for bass lovers. Performance should be acceptable for general music use though.
