4.3 out of 5 - Best Budget Portable Speaker Under $35
Product Overview
The Soundcore Select 4 Go is Anker's answer to the ultra-compact speaker market, and it punches well above its weight. Measuring just 121 by 83 by 48.5 mm and weighing only 265 grams, it is compact enough to fit in the palm of your hand or slip into any pocket, yet it delivers sound quality and battery life that rivals speakers twice its size and price. The rectangular design with rounded edges feels modern and practical, wrapped in a durable woven fabric that resists scratches and wear from outdoor use.
What truly sets the Select 4 Go apart from competitors is its extraordinary 20-hour battery life — nearly triple the endurance of the JBL Go 5 and double that of most speakers in this category. The IP67 rating means it is not just waterproof but fully dustproof, and it actually floats in water, making it perfect for pool parties, beach trips, and shower listening. The built-in carrying strap adds versatility for clipping to backpacks or bike handles. Available in multiple colors including Black, White, Blue, and Green, there is a style for every taste. Our expert team at Devixo Store has rigorously tested the Select 4 Go across indoor listening, outdoor adventures, water exposure, and extended battery drain tests to bring you a comprehensive, honest assessment of its real-world performance.
Why Buy This Product?
The Soundcore Select 4 Go stands out as the best value ultra-compact portable speaker for several compelling reasons. First, the battery life is simply unmatched in this price category. While most competitors offer 5-7 hours of playback, the Select 4 Go delivers up to 20 hours at moderate volumes — enough for multiple days of use without reaching for a charger. This makes it the ideal travel companion, gym buddy, or camping essential. The sound quality is impressive for the size: the 1.75-inch driver produces punchy, clear audio with a passive radiator adding genuine bass depth that you can feel. Vocals are crisp, the midrange is well-defined, and the overall tuning is energetic and engaging — perfect for pop, hip-hop, and electronic music.
Second, the durability and versatility are exceptional for just $30. The IP67 rating means complete protection against dust and water, and the floatable design is a genuine game-changer for pool and beach use. The True Wireless Stereo feature lets you pair two speakers for a surprisingly immersive stereo experience that rivals much more expensive setups. The Soundcore app adds value with customizable EQ, firmware updates, and battery monitoring. The carrying strap is a thoughtful touch that makes the speaker infinitely more practical than smooth, strapless competitors. At our store, we rigorously test every product for audio quality, build durability, battery accuracy, and real-world usability — and the Select 4 Go consistently earns top marks as the best budget portable speaker under $35, with users on Reddit praising its astonishing battery life, clarity, and water resistance.

Frequently Asked Questions
1
How long does the Soundcore Select 4 Go battery last?
The Soundcore Select 4 Go features a 2,400mAh battery that delivers up to 20 hours of continuous playback at 40% volume in Balanced EQ mode. This is one of the longest battery lives in the ultra-compact speaker category — nearly triple the JBL Go 5's 7-hour rating. Real-world testing by RTINGS confirmed approximately 10 hours of continuous playback at higher volumes, while Reddit users report getting 15-18 hours with mixed usage at moderate levels. Battery life varies significantly depending on volume level, audio content (bass-heavy tracks drain more power), custom EQ settings, and environmental temperature. The speaker does not have a quick charge feature, but the efficient power management ensures exceptional endurance. The power button indicator flashes red when the battery drops below 10%, giving you ample warning to recharge.
2
Can I use the Soundcore Select 4 Go in the pool or shower?
Yes, the Soundcore Select 4 Go is rated IP67, meaning it is both completely dustproof and waterproof. The speaker can withstand immersion in water up to 1 meter (3.3 feet) deep for up to 30 minutes without damage. Uniquely, the Select 4 Go is also floatable — it will bob on the surface of water rather than sinking, making it ideal for pool parties, beach trips, and lake outings. Before submerging the speaker in water, ensure the waterproof rubber cover over the USB-C charging port is sealed tightly — this is critical for maintaining the IP67 protection. After exposure to salt water or chlorinated pool water, rinse the speaker with fresh water and dry it thoroughly, especially around the charging port. Do not charge the speaker while it is wet or damp. The floatable design is a standout feature that most competitors in this price range do not offer.
3
How does the True Wireless Stereo (TWS) mode work?
True Wireless Stereo (TWS) allows you to pair two Soundcore Select 4 Go speakers together to create a true left/right stereo setup with genuine channel separation. To activate TWS, first connect one speaker to your smartphone via Bluetooth. Then, press and hold the Bluetooth button on both speakers simultaneously for approximately 2 seconds. The speakers will automatically pair with each other, with one becoming the left channel and the other the right channel. You will hear an audio prompt confirming the connection. This creates a surprisingly wide and immersive soundstage that far exceeds what a single speaker can deliver. TWS mode works best indoors where the speakers can be placed 3-6 feet apart. Note that TWS pairing is only possible between two Select 4 Go speakers — you cannot pair a Select 4 Go with a different Soundcore model or with speakers from other brands. Two Select 4 Go speakers cost less than $60 combined, making this an incredible value stereo setup.
4
What is the sound quality like on the Soundcore Select 4 Go?
The Soundcore Select 4 Go delivers surprisingly capable sound for its compact size and budget price. The 1.75-inch (45mm) full-range driver produces punchy, clear audio with a warm tuning that emphasizes bass and vocals. The passive radiator adds genuine bass depth and rumble that you can feel — a rarity in speakers under $35. Vocals come through clearly and forward in the mix, making it excellent for podcasts, audiobooks, and vocal-heavy music. The midrange is well-balanced, and the treble is crisp without becoming harsh. At maximum volume, some compression is noticeable, but distortion is minimal thanks to Soundcore's DSP tuning. The sound is not audiophile-grade, but for casual listening, desk use, small rooms, and outdoor gatherings, it punches well above its weight. The Soundcore app allows you to customize the EQ to your preference, with presets for different music genres and a custom EQ option.
5
Can I use the Soundcore Select 4 Go for phone calls?
No, the Soundcore Select 4 Go does not have a built-in microphone and does not support phone calls or voice assistant activation. This is a deliberate design choice to keep the speaker as compact and affordable as possible. When a call comes in while the speaker is connected to your phone, the audio will not route through the speaker — you will need to answer the call on your phone directly or disconnect the Bluetooth connection. If speakerphone functionality is important to you, consider alternatives such as the JBL Go 5 (which has a basic microphone) or the Tribit StormBox Mini (which supports calls and voice assistants). The absence of a microphone is a trade-off that most users accept given the speaker's exceptional battery life, waterproofing, and TWS capability at just $30.
6
Does the Soundcore Select 4 Go support the Soundcore app?
Yes, the Soundcore Select 4 Go is fully compatible with the Soundcore mobile app, available for free on both Android (Google Play Store) and iOS (Apple App Store). The app does not require an account to use the basic features. Through the app, you can access customizable EQ settings with multiple presets (including Balanced, Bass Boost, Treble Boost, and more) and a custom 9-band EQ to create your own sound profile. The app also displays the current battery percentage, allows you to manage the sleep timer, and handles firmware updates to keep your speaker running the latest software. Note that if you have an older version of the Soundcore app installed, Soundcore recommends uninstalling and reinstalling it to ensure compatibility with the Select 4 Go. The app interface is clean and intuitive, making it easy to tweak your sound even if you are not tech-savvy.
7
What audio codecs does the Soundcore Select 4 Go support?
The Soundcore Select 4 Go supports the standard SBC Bluetooth codec. It does not support higher-quality codecs such as AAC, aptX, aptX Adaptive, or LDAC. SBC is the universal Bluetooth codec supported by all smartphones, tablets, and computers, ensuring 100% compatibility across all devices. While audiophiles may prefer AAC for Apple devices or aptX for Android, the difference is negligible on a speaker of this size and price point. The 1.75-inch driver and 5W output power are not capable of resolving the subtle improvements that advanced codecs provide. Bluetooth 5.4 ensures a stable, low-latency connection with an effective range of approximately 10 meters indoors and up to 30 meters (98 feet) in open outdoor areas — significantly better than the range of many competitors. The frequency response covers the standard 100Hz to 20kHz range, which is appropriate for the driver's size.
8
Can I connect the Soundcore Select 4 Go via a wired connection?
No, the Soundcore Select 4 Go does not have a 3.5mm auxiliary input jack and does not support wired audio connections. It is a purely wireless Bluetooth speaker. The only physical port is the USB-C charging port, which is exclusively for charging the internal battery. This design choice keeps the speaker as compact, simple, and waterproof as possible — eliminating the aux port removes a potential point of water ingress and reduces internal complexity. To play audio, you must connect a Bluetooth-enabled device such as a smartphone, tablet, laptop, or MP3 player. If you need a wired connection for devices without Bluetooth, you will need to either use a Bluetooth transmitter or choose a different speaker that includes an aux input, such as the Tribit StormBox Mini. The USB-C port does not support USB audio playback or power bank functionality.
9
How do I control playback and volume on the Soundcore Select 4 Go?
The Soundcore Select 4 Go features intuitive physical controls located on the top panel of the speaker. The control layout includes: a power button (press and hold to turn on/off), a Bluetooth pairing button (press to enter pairing mode or hold for TWS pairing), a play/pause button, and volume up/down buttons. The buttons are raised and tactile, making them easy to locate by feel even in wet conditions or while the speaker is in a bag. The LED indicator on the front of the speaker shows Bluetooth connection status: solid blue when connected to a device, flashing blue when in pairing mode, and red when charging. When the battery drops below 10%, the power button indicator flashes red to warn you. The controls are straightforward and do not require the app for basic operation. There is no dedicated track skip button — track control is handled through your connected device.
10
How does the Soundcore Select 4 Go compare to the JBL Go 5?
The Soundcore Select 4 Go and JBL Go 5 are both excellent ultra-compact speakers, but they target slightly different priorities. The Select 4 Go wins decisively on battery life (20 hours vs. 7 hours) and price ($30 vs. $50), while offering True Wireless Stereo pairing and a floatable design — features the JBL Go 5 lacks. The JBL Go 5 counters with a more premium brand reputation, a wider range of color options (12 vs. 4), a built-in microphone for calls, and slightly more refined bass tuning thanks to JBL's Pro Sound DSP. Both speakers deliver 5W output, have IP67 waterproof ratings, and use Bluetooth 5.3/5.4. The Select 4 Go supports the Soundcore app for EQ customization, while the Go 5 has no app support. For budget-conscious buyers who prioritize battery life and value, the Select 4 Go is the clear winner. For buyers who want a premium brand, more colors, and call functionality, the Go 5 is worth the extra $20. Both are excellent choices in their respective price brackets.
