Design and Build Quality

The JBL Go 4 features an ultra-portable design that is both waterproof and dustproof, making it an excellent choice for outdoor activities. Its IP67 rating ensures it can withstand various environments, from poolside gatherings to beach outings. The compact size allows it to easily fit in the palm of your hand, while the colorful options let users express their style. In contrast, the Marshall Emberton III also boasts a rugged, waterproof design with an IP67 rating, but it stands out with its classic rock-inspired aesthetics, featuring a textured sleeve and iconic Marshall script. This speaker is designed not just for portability but also to endure various outdoor conditions.

Sound Quality

When it comes to sound, the JBL Go 4 delivers impressive JBL Pro Sound, characterized by punchy bass and clarity, especially considering its small size. Users can experience up to 7 hours of playtime, making it a great companion for day trips. On the other hand, the Marshall Emberton III is engineered for a fuller sound experience with deep bass and true stereophonic capabilities that provide multi-directional sound. This means every listening position feels like a sweet spot, making it ideal for gatherings. With over 32 hours of playtime, it supports long listening sessions without interruption, which is significantly more than the Go 4.

Battery Life

The JBL Go 4 offers a commendable battery life of up to 7 hours on a single charge, with the ability to extend this by an additional 2 hours through its Playtime Boost feature. This makes it suitable for short outings and casual listening. In contrast, the Marshall Emberton III excels in this department, boasting more than 32 hours of playtime. This vast difference in battery life can be a decisive factor for users who prioritize extended use, making the Emberton III a better choice for longer trips or outdoor events.

Connectivity Options

Both speakers offer modern Bluetooth connectivity, but the JBL Go 4 has an edge with its multi-speaker connection capability via Auracast. This feature allows users to pair two Go 4 speakers for stereo sound or connect multiple JBL Auracast-enabled speakers for an even larger audio experience. The Marshall Emberton III is also Bluetooth LE Audio-ready, promising superior sound quality and new audio sharing possibilities. However, it does not provide the same multi-speaker connectivity options as the Go 4, which may limit its versatility in larger gatherings.

Price

The JBL Go 4 is currently priced at $39.95, making it about 78% cheaper than the Marshall Emberton III, which retails for $179.99. This significant price difference makes the Go 4 an attractive option for budget-conscious consumers looking for quality sound in a portable package. However, the Emberton III’s price reflects its extended features, including enhanced sound quality and battery life. For those who value these aspects over cost, the Emberton may justify its higher price.

Brand Reputation and Popularity

JBL holds a strong position in the market, with the Go 4 ranking 34th in sales, indicating its popularity among consumers. This suggests a high level of customer satisfaction and trust in the JBL brand. Meanwhile, the Marshall Emberton III has a sales rank of 2153, which, while respectable, indicates it may not be as widely adopted as the Go 4. This difference in ranking can influence a buyer's decision, especially if they prioritize trending products with proven sales success.

Portability

The JBL Go 4 is designed with portability in mind, fitting comfortably in the palm of your hand and featuring a newly redesigned integrated loop for easy carrying. It’s a perfect companion for casual outings, picnics, or spontaneous adventures. On the other hand, the Marshall Emberton III is also portable but carries a slightly bulkier form factor. While it is rugged and travel-ready, the Go 4’s size and lightweight design give it a clear advantage for those who prioritize easy transport.

Which should you buy?

Choosing between the JBL Go 4 and the Marshall Emberton III ultimately comes down to individual needs and preferences. If you prioritize portability, affordability, and a decent sound experience for shorter outings, the JBL Go 4 is an excellent choice at $39.95. However, if you seek superior sound quality, longer battery life, and a rugged design that can withstand the elements for extended periods, the Marshall Emberton III, priced at $179.99, will likely provide greater satisfaction. Each speaker has its strengths, so consider what features resonate most with your lifestyle.
