What reviewers said

7Hz Legato

The 7Hz Legato is a budget-friendly dual-dynamic-driver IEM tuned for maximum fun, delivering a powerful, bass-forward sound with a smooth yet lively character. It offers a wide soundstage and solid build quality, making it a great pick for gaming or listeners who crave a warm, energetic signature rather than analytical precision. However, its heavy low end and V-shaped tuning won't suit purists seeking neutrality or top-tier detail retrieval.

Pro:Punchy, thunderous bass response
Pro:Lively and engaging tuning
Pro:Good soundstage for the price

Con:Bass can overwhelm some listeners
Con:Treble boost may reduce timbral realism
Con:Midrange clarity and separation are limited

Kiwi Ears KE4

The Kiwi Ears KE4 is a wired hybrid IEM that offers a balanced, relaxing sound with a distinct twist on the popular 'New Meta' tuning, adding extra bass and treble sparkle. It delivers solid midrange clarity and a comfortable fit, making it a versatile choice for many genres, though its smooth presentation may not excite those seeking aggressive or highly dynamic sound.

Pro:Well-balanced hybrid tuning with rich lower mids and airy treble
Pro:Comfortable fit and broad genre versatility
Pro:Good resolution and clarity for its price

Con:Sub-bass can get overpowering at times
Con:Limited resolving power and dynamic impact
Con:Smooth tuning may feel less exciting than V-shaped alternatives
