Key Considerations
Sound Quality & Output Power: Even a small speaker should aim for balanced audio (bass, mids, highs) and a reasonable output level (volume). Driver size, amplifier power (W), and acoustic design affect how good “music quality” is.
Portability & Weight: Smaller, lighter speakers are easier to carry around — useful if you travel, commute, or move often. For “on-the-go” devices, portability is often more important than absolute audio power.
Battery Life & Power Management: Since there’s no wired power when mobile, battery capacity and how efficiently the speaker uses power determine how long you can listen. This affects practicality for travel, outdoor use, long sessions.
Durability & Water/Dust Resistance: For outdoor, pool-side, travel, or unpredictable environments, waterproof and dust-proof design ensure longevity and reduce the risk of damage.
Connectivity & Compatibility: Modern Bluetooth version, stable wireless connection, and ability to connect multiple speakers or different devices increase versatility and ease of use.
The Go 4 is ultra-portable: weight is only ~190 g, and dimensions ~94.3 × 75.7 × 42.2 mm. Its size makes it easy to carry in a backpack, handbag — even hang on a bike or bag strap for travel or outdoor use. The small loop/strap helps with portability. For people who want a speaker for travel, commuting, or quick outdoor sessions, this portability is a major advantage. The speaker is rated IP67 — meaning it’s waterproof and dustproof, so you can use it near water (pool, beach, bathroom) or dusty/windy outdoor places.
These factors represent the most critical aspects that will impact your satisfaction with this product.
Customer Reviews
I love how tiny this speaker is. It literally fits right into my hand. Sound is surprisingly powerful with nice, punchy bass. I use it all the time in my car because I have two kids, and it’s not always easy to hear music or podcasts over the noise. This little speaker makes a big difference!
Sweet little gizmo! Slick design (I got the red one), The speaker fits in my hydration vest pocket easily. Extremely portable! I run and hike alone so like this for company!
