Brainwavz Delta vs Bluedio T4

These earphones produce a punchy sound with a good level of detail. The bass is not overpowering, but instead is fast and controlled with good depth. The mids sound natural, while the highs sound airy without getting harsh. These should sound good for all genres of music.

For a $20 pair of earphones, these are built incredibly well. The earpieces are made out of metal which makes them quite durable and resistant to damage. The cables are soft and flexible, and shouldn't break easily.

It's easy to unpack the Delta. Just open the box and there they are.

This set can be used for talking on the phone.

These come with 3 sets of silicon tips and 1 set of foam tips. The big selection of tips play a role in the notoriously comfortable fit provided by these buds.

Most earbuds have microphonics, where the movement of attached wires can cause unwanted noise that can drown out music.Surprisingly, these buds have no microphonics whatsoever.

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.
