66 Audio BTS Pro vs V-MODA Crossfade 2 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.

These headphones feel high quality, and give the impression that they will last long. The headband is made out of metal which is very resistant to damage, yet also is quite flexible. The ear cups are made of thick plastic and not feel brittle, while the aluminum shields add a satisfying heft and premium feel to the headphones.

The Crossfade 2 Wireless produces detailed audio with a good level of oomph. The highs are boosted, so you’ll be able to hear a lot of detail from your music. However, the high frequencies do not get harsh, so these are quite easy to listen to for extended periods. The bass is powerful, as with most of V-Moda’s headphones. However, the bass does not sound bloated, so overall clarity of the audio is still very good, and the punchy bass helps make music sound more exciting.

These headphones won’t have a pinching effect on your head. The ear cups as well as the headband feature really thick cushioning, so these headphones will feel very soft on the head.

You’ll get long hours of wireless music listening off these headphones. The Crossfade 2 can deliver around 13 to 14 hours of music playback from a full charge. Should the battery run out, these headphones can also function wired, so you can go on with your music listening.

You can easily control your music using the buttons on the left ear cup. You get a pause/play/skip/digital assistant button, as well as volume adjustment functionality.

These headphones can get adequate protection from scratches and bumps if you use the included case. It is a hard shell plastic case with a felt inner lining and is durable enough to withstand minor impact. The case is compact (modeled after the headphones when folded) so you can easily fit the case in your bag.

These headphones can be easy to travel with. You can fold the ear cups and yokes up to the headband, reducing the overall footprint. You can easily chuck these headphones into a bag or large purse with ease.
