I don't see this one on the web yet.. And I'll be visiting the retail store soon, but in contrast to my iPhone 6, the 6s + speaker sounds very hollow until about 3/4 volume. I thought it was just one album or a bad song to play with (maybe had soft highs), but realized it's all sound from the main speaker. Somewhere between 1/2 and 3/4 volume there's a strong improvement in the highs. I put the 6 next to it, and by contrast the clarity is amazing on my 6. Anyone else out there seeing this?
