The only two IEM's I bought in a store would be the LG Tone and the Klipsch S4i. Between the two, the S4i does have quite more bass impact than the Tone.
But, I would not suggest the S4i, the sound quality is sub par for the price that I paid for it, if it was closer to like 40, I would not mind it but at 100 msrp, just no.
On the other hand, the Tone, which is bluetooth, was only 45 dollars and I still am amazed at the sound, for it being bluetooth anyhow!
