After being so satisfied with the HAS160 I wanted to see if this would be a good improvement on it. It isn't. While the bass is a bit better than on the HAS160, the treble is much worse. The HAS650 has better bass and better sound overall, and much better build quality. The treble on the HAS160 is better than the treble on the HAS650 though. I am glad I bought the HAS160, HAS600, and the HAS650, and regret buying the HAS360. Save your money and don't buy this one. Ironically I paid less for the HAS600 than for the HAS360. Even though I regret buying this, I still think it sounds a bit better than the Portapro, and has a similar warm sound signature. Buy the HAS650 if you want a warm sound with extra bass. Buy the HAS160 if you want better treble and want a more balanced sound. Avoid this.
