Key specifications

• Audio output: 5 watts
• Connectivity: Bluetooth 5.4. It supports multi-device pairing and has a wireless range of up to 30 meters.
• Battery life: The manufacturer advertises up to 20 hours of playtime. Real-world testing shows about 10 hours at a high volume level.
• Durability: It has an IP67 rating, making it completely protected from dust and able to be submerged in water up to 1 meter deep for 30 minutes. The speaker is also able to float.
• Size and weight: The speaker weighs 265 grams and is lightweight enough to be easily carried with one hand or in a bag.
• Other features:
  • True Wireless Stereo (TWS): You can pair two Select 4 Go speakers for an immersive stereo sound experience.
  • Soundcore app: The app allows you to customize the sound using a 9-band graphic EQ and select from various EQ presets.
  • Integrated strap: It includes a built-in strap for easy carrying and attachment to a backpack.
  • Mono sound: On its own, the speaker is mono, so you must pair two units for stereo playback.

• Sound quality: Given its small size, the 5W mono speaker produces a “surprisingly full” and punchy sound. While the sound is clear and detailed in the mid and high ranges, there is a noticeable lack of deep bass. The app’s customizable EQ can be used to mitigate some of the sound limitations.
• Portability: Its small size, light weight, and built-in strap make it a great companion for outdoor activities like hiking, camping, or trips to the beach.
• Durability: The build quality is excellent, with a tough fabric weave and silicone covering. Its IP67 rating ensures it can handle exposure to dust and water, including floating in a pool.
• App features: Support for the Soundcore app is a significant bonus for an entry-level speaker, offering customizable EQ settings that let you fine-tune the sound profile. 

• vs. JBL Go 4: The Select 4 Go is slightly larger but offers more than double the battery life (20 hours vs. 7 hours) and more versatile EQ options via the app.
• vs. JBL Clip 5: The Clip 5 provides more powerful 7W sound and deeper bass, but it has a shorter battery life (12 hours) and costs significantly more. The Clip 5 has a carabiner, while the Select 4 Go has a more basic strap loop.
• vs. Tribit Stormbox Micro 2: The Tribit speaker includes a microphone for voice assistants and can function as a power bank, but the Select 4 Go is the cheaper option
