GOBOULT Z40 V2.0: Quick Specifications
GOBOULT Z40 V2.0 Overview
The Z40 V2.0 is the updated version of GOBOULT's Z40 wireless earbud concept. Its main focus is delivering a feature-heavy package at a relatively accessible price, with a large 13mm driver, extended battery life and gaming-focused low latency.
The supplied Amazon listing identifies this model as the Z40 V2.0 and gives it up to 70 hours of playtime, Quad Mic ENC, 45ms low latency, IPX5 protection and Bluetooth 5.4.
Design & Comfort
The Z40 V2.0 uses a compact true-wireless in-ear design with separate left and right earbuds housed inside a portable charging case.
The in-ear construction is intended to create a more secure seal than open-style earbuds. Actual comfort and isolation will depend on the user's ear shape and the supplied ear-tip size.
Sound Quality & 13mm Bass Drivers
GOBOULT equips the Z40 V2.0 with 13mm drivers designed to deliver a bass-focused listening experience. The larger driver format is aimed at giving music, movies and casual gaming a fuller low-frequency presence.
Listeners who prefer energetic Bollywood, EDM, hip-hop and other bass-heavy music should find the tuning concept particularly appealing.
Bass-Focused Sound
The Z40 V2.0 is positioned more toward an enjoyable, punchy everyday sound signature than a studio-monitoring presentation. Buyers looking for a neutral or highly analytical tuning may prefer a different model.
Quad Mic ENC & Calling
The Z40 V2.0 features a four-microphone environmental noise cancellation setup designed to improve voice pickup during calls.
ENC is primarily intended to help the microphone system separate the user's voice from surrounding environmental noise. It should not be confused with Active Noise Cancellation for music playback.
45ms Low-Latency Gaming Mode
Gaming is one of the key selling points of the Z40 V2.0. GOBOULT specifies latency as low as 45ms in its low-latency gaming mode.
Lower latency can reduce the perceived delay between an action on a smartphone and the corresponding audio, which is useful for mobile games and rhythm-based titles.
Use-Case Assessment
These are editorial use-case assessments based on the listed feature set, not laboratory benchmark results.
70-Hour Battery Life
Battery life is one of the strongest headline specifications of the Z40 V2.0. GOBOULT lists up to 70 hours of total playtime with the charging case.
The large total-playtime figure is particularly useful for users who do not want to recharge their earbuds frequently during commuting, travel, work or entertainment.
Actual battery life varies with volume, codec, usage, connectivity, gaming mode and other conditions.
Bluetooth 5.4 & Wireless Connectivity
Bluetooth 5.4 provides the wireless connection between the earbuds and a compatible smartphone, tablet or other Bluetooth audio source.
The Z40 V2.0 is intended for everyday wireless listening across smartphones, laptops, tablets and other compatible Bluetooth devices.
