These headphones sound far better than they should given the price, and even outperform my previous favorite headphones audio quality wise. They improve on the audio balance, providing a more even mix of treble and bass. The only thing I don’t like about them is the little rubber bits that grip onto my ears: they’re made a thin and cheaper material and don’t do much.

The Q9 headphones are an inexpensive set of Bluetooth headphones that look good and have acceptable audio quality with deep bass and rich mids. Fans of bassy music will like these headphones the most – their bass is strong, but at times can muddy the treble. They’re not at clear as my current favorite sport headphones, the Mpow Swift, but most won’t notice the difference unless they have the two sets to compare.
