Overview of INSMY Small Bluetooth Speaker and Soundcore Select 4 Go
The INSMY Small Bluetooth Speaker is priced at $18.89, making it about 17% cheaper than the Soundcore Select 4 Go at $24.99. Both speakers are designed for portability and convenience, but they cater to slightly different needs and preferences. The INSMY speaker provides a compact and lightweight option for casual listening, while the Soundcore speaker promises extended battery life and robust outdoor capabilities.
Design and Portability
When it comes to design, the INSMY Small Bluetooth Speaker features a compact metal body with a braided lanyard, making it easy to carry. Weighing only 100g and measuring 50 x 50 mm, it's as portable as it gets. In contrast, the Soundcore Select 4 Go also emphasizes portability with a lightweight design and an included strap. While both speakers are designed for on-the-go use, the INSMY speaker's golf-ball size gives it a slight edge in ultra-compact portability.
Audio Quality
In terms of audio performance, both speakers deliver surprisingly punchy sound for their size. The INSMY speaker boasts a 5W full-range speaker and a hidden passive radiator, providing rich audio and clear sound. Conversely, the Soundcore Select 4 Go also features a 5W output and emphasizes its ability to deliver powerful sound, ensuring clear and dynamic audio. While both speakers promise impressive sound quality, the INSMY's stereo pairing feature could enhance the listening experience for users who want to amplify their sound.
Battery Life
Battery life is a significant factor for portable speakers, and here, the Soundcore Select 4 Go shines with an impressive 20-hour playback on a single charge. In comparison, the INSMY Small Bluetooth Speaker offers up to 10 hours of playback at 50% volume. This means that Soundcore's offering lasts twice as long, making it the better choice for extended outings where charging may not be possible.
Durability and Water Resistance
Both speakers are designed with outdoor use in mind, but they vary in their water resistance capabilities. The INSMY Small Bluetooth Speaker is waterproof and shockproof, making it suitable for various outdoor activities. However, the Soundcore Select 4 Go takes the lead with its IP67 rating, which allows it to be submerged in water up to 3.3 feet for 30 minutes. This makes the Soundcore more reliable for users who intend to use their speaker in wet environments, like beaches or showers.
Connectivity Features
When it comes to connectivity, both speakers feature Bluetooth technology and support wireless stereo pairing. The INSMY speaker connects easily with devices and allows for stereo pairing with another unit for enhanced sound. The Soundcore Select 4 Go also supports True Wireless Stereo (TWS) pairing, enabling users to connect two speakers for a richer audio experience. Both offer seamless connectivity, but the TWS pairing feature of the Soundcore may be more appealing to those who seek a more immersive sound experience.
Price Comparison
The INSMY Small Bluetooth Speaker is priced at $18.89, while the Soundcore Select 4 Go is available for $24.99. This means that the INSMY speaker is about 17% cheaper, making it an appealing option for budget-conscious consumers. However, the Soundcore's additional features, such as longer battery life and superior water resistance, may justify its higher price for users who prioritize outdoor use and extended playback.
Which should you buy?
Choosing between the INSMY Small Bluetooth Speaker and the Soundcore Select 4 Go ultimately depends on your specific needs. If you're looking for a compact, budget-friendly option with decent sound quality for casual use, the INSMY speaker is a solid choice. However, if you value extended battery life, superior water resistance, and the ability to enjoy music in harsher conditions, the Soundcore Select 4 Go is worth the extra investment. Both speakers have their strengths, so your decision should align with your lifestyle and listening habits.
