I drive a UPS truck and its as noisy as can be and I can hear great with the LG Tones. I love the vibration feature. I have not tried the Jays, but have heard great things. The LG Infinims sound great, but the durability is terrible. Upgraded my 750's around 2 months ago and the Infinims have already broke (left ear piece went out and the retractable buds do not feel durable......read the reviews on Amazon, etc). I'm back to the LG 750's which have lasted since they came out.
