Monster iSport Victory vs 66 Audio BTS Pro

These headphones are designed with joggers and gym rats in mind. They won't stop working due to rain or sweat. They can even be washed, as long as it's done carefully and by hand.

The highs are crisp, the mids are clean and bass over-emphasized, but not as much as to overwhelm everything else.

Noise isolation is very good with these headphones, and should effectively minimize ambient noise. These headphones form an effective seal inside the ears due to the quality ear tips and the sport clips that help keep these in place.

iSport Victory headphones have a 3.8-foot cable that is soft and flexible and does not tangle easily.

Monster iSport Victory headphones come with 5 sets of extra eartips from small to extra large sizes allowing you to adjust the size of the earbuds to fit your needs.

These headphones use a patented earclip to help them comfortably stay in your ear.

You can answer calls by clicking the middle button on the remote.

These headphones come bundled with:

• a small pouch
• a clothing clip
• 5 sets of extra eartips
• extra earclips

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.
