Bass and treble is great, noise cancell is best, will purchase more sets and best for gym.

7 Waterproof Stereo Earphones (Bluetooth 4.1, Secure Fit Lightweight Design, CVC 6.0 Noise Cancelling Mic, Fast Pairing)These great sounding Otium earphones provide crisp, clear sound and dynamic bass for a small fraction of what you would think they cost

The bass isn't too overpowering, and the sound is really accurate

The sound is good (bass, good volume control), good microphone, can hear calls/be heard well, buds stay in mostly, but they fall out a little easily

Easy to connect, good sound quality for the price, decent range with good bass and treble

These otium sport headphones have great sound with nice bass

For the price, I didn't expect much, and at first glance with the thin wire and the light weight feel I expected these to sound tinny and lacking any volume and bass

Great bass

These have a very nice and heavy bass that is not overwhelming, the mids and highs are also quite good for it's price range

Some headphones make things sound quite tin-ny but this has good bass.

The earbuds fit comfortably in my ears with the default ear tips and the sound quality is surprisingly better than expected with a slightly boosted bass range

If you've never tried Bluetooth headphones at the gym or while working around the house, give these a
