Unless the item I received was faulty in some way, this is the lousiest sound quality I have experienced for the price. The max volume is low and the sound doesn't carry outside, low bass, mid-tones and vocal cracking up if you increase the volume beyond 50%. The app equalizer acts weird: When increasing bass, the low frequencies don't increase, but the treble gets reduced! I had great expectations after reading reviews and listening to (demo) music in stores before purchasing. But sorry, there's no "boom" or "mega boom" about this product at all! Returning for a full refund.
