A Brief Comparison
Apos Audio Rock Lobster
Price: $100.00
+ Kitschy theming with a faultless build
+ Excellent ergonomics – as comfortable as the vicace
+ Mid-bass dominant sound signature for a dynamic and engaging listen
+ Forgiving tuning
– Slightly dark, with a softer treble response
– Upper-treble lacks equal energy and bite to the Vivace.
Tripowin X oB Audio Vivace
Price: $39.99
+ Well-finished resin-build that is both durable and lightweight
+ Excellent ergonomics, sitting in my ears snugly with not prominent hotspots.
+ Pleasant and non-offensive signature, but a clean presentation from top-to-bottom
+ Warm and inviting midrange and satisfyingly balanced-but-dense bass response.
– Above-average imaging but weak, narrow staging
– Upper-treble lacks energy and bite.
Conclusive Remarks

The Rock Lobster doesn’t ignite new trends, but it’s a straight-shooting, no-nonsense IEM that lets you kick out the jams. It’s not a technically proficient virtuoso, but it’s a great ball of fun and it adds a sombre edge to the wails of teen angst amidst mid-west suburbia.
