Plantronics BackBeat Fit vs Bluedio T4

Connectivity with source devices is via Bluetooth, so in place of a full headphone cable is a flexible, soft and short cord made of rubber material that keeps the earpieces connected. You won't have to deal with a long and dangling cable.

The highs are not the most detailed, but they are clear and do give an airy feel to the music. The mids are full and forward so vocals will definitely sound great.

Bass is hit or miss though, depending on how well these headphones seal in your ear. If there is a good seal then bass is punchy and tight though not very powerful. Otherwise, it is likely that the bass will sound a bit on the thin side.

The case can be converted into an armband by reversing it inside out. This is very useful as you can use the arm band to store your smartphone while on a run, along with some essentials like your keys or some cash.

The ear tips are made out of a soft and flexible material that is comfortable and supports the weight of the earpieces quite well. This is enhanced by the wing tips that further help to keep the headphones in place.

The design does not create a thorough seal in your ears, which can be a good thing as this will allow you to maintain awareness of what's around you.

The BackBeat Fit can last up to 8 hours of playback from a full charge.

A sweat resistant coating is applied to the interior parts, so splashes of liquid aren't likely to cause damage.

Each of the earpieces have a single button. Different combinations of presses will allow you to pause/play tracks, answer/end calls, adjust volume and do other functions which can be convenient.

The audio from the microphone is not amazing, but it is quite clear with no distortion so it should be good for most conversations.

These headphones should last you quite a while, as they are built well. The hinges and the headband adjustment are made of metal, with sturdy plastics on the earcups. These should survive being thrown into a bag and minor drops without issue.

The sound is on the neutral side instead of boosted bass or highs. Overall the sound has good clarity with okay details on the treble along with tight and low-end. The mids are slightly recessed though.

You won’t easily hear engine noise and the like. The active noise cancelling is quite effective at filtering out low-pitched, droning noise.

You can continue using these headphones even when the battery runs out. Aside from Bluetooth connectivity, these also come with a USB Type C to 3.5mm cable, so these can be used as wired headphones. You won’t get active noise cancelling without battery power though.
