Bose SoundLink Micro Generations: What Changed?
The Bose SoundLink Micro has had two generations: the original (2017) and the second generation (2021). The main changes are a slightly longer battery life (up to 6 hours vs. 5 hours), a new color option (Blue Dusk), and a refreshed fabric finish, while the core design, sound quality, and waterproof rating remain essentially the same.
Background: Why Two Generations?
Bose introduced the SoundLink Micro in late 2017 as their smallest portable Bluetooth speaker, aimed at outdoor use with a rugged, waterproof design and a silicone strap for attaching to bags or bikes. It was well-received for its surprisingly full sound for its size, but the battery life (around 5 hours) was often criticized. In 2021, Bose released a second generation with modest updates rather than a full redesign. The company positioned it as a refresh rather than a replacement, keeping the same form factor and acoustic architecture while addressing the most common complaint—battery endurance—and adding a fresh colorway.
Key Differences Between Gen 1 and Gen 2
Here are the concrete changes you’ll notice when comparing the two versions side by side:
- Battery life: Gen 1 offers up to 5 hours of playtime; Gen 2 extends that to 6 hours at moderate volume. Real-world usage varies with volume and content, but the extra hour is a genuine improvement.
- Color options: Gen 1 came in Black, Blue, and Orange. Gen 2 offers Black, Blue Dusk (a muted teal-gray), and Stone (a light gray). The Orange option was dropped.
- Fabric and finish: Gen 2 uses a slightly different silicone and fabric blend that feels a bit more textured and resistant to dust. The strap is also marginally stiffer, making it easier to clip.
- Charging port: Both use Micro-USB. Yes, even the Gen 2 still uses Micro-USB, not USB-C—a common point of disappointment among users.
- Bluetooth version: Gen 1 uses Bluetooth 4.2; Gen 2 uses Bluetooth 5.0. This improves range slightly (up to 30 feet) and connection stability when moving between devices.
- Weight and dimensions: Identical. Both weigh 10.2 ounces (290g) and measure 3.9 x 3.9 x 1.4 inches.
Sound and Performance: Any Real Change?
Bose claims the sound signature is unchanged between generations, and most reviewers agree. Both produce a surprisingly rich sound for a speaker this small, with a passive radiator delivering more bass than you’d expect. The Gen 2 does have a slightly updated DSP (digital signal processing) that reduces distortion at maximum volume, but the difference is subtle. If you’re upgrading for sound alone, you won’t notice a major improvement. The speaker still gets loud for its size, but it’s not designed for large rooms or outdoor parties—it’s meant for personal listening, showers, or attaching to a bike.
How to Tell Which Generation You Have
If you’re buying used or want to check your own speaker, there are a few quick tells:
- Model number: Gen 1 is model 791234-0010 (or similar); Gen 2 is model 791234-0020. Check the underside of the speaker or the box.
- Color: If it’s Blue Dusk or Stone, it’s definitely Gen 2. If it’s Orange, it’s Gen 1.
- Battery test: Play at a moderate volume and time how long it lasts. If it exceeds 5 hours, it’s likely Gen 2.
- Bluetooth pairing: Gen 2 pairs a bit faster and supports the Bose Connect app’s “Find My Speaker� feature more reliably, but that’s not a definitive test.
Common Problems and Misconceptions
Owners of both generations report similar issues, so don’t expect Gen 2 to fix these:
- Micro-USB port: Both use the older connector, which is fragile and can break if the cable is yanked. Be gentle when charging.
- Battery drain: Some Gen 1 units lose charge when left idle for weeks. Gen 2 improved standby time, but it’s still not perfect—store it with a partial charge.
- Water resistance: Both are IPX7, meaning they can be submerged in up to 1 meter of water for 30 minutes. However, the charging port cover must be fully closed. If the cover is loose, water can seep in and damage the speaker.
- “Why does it sound muffled?� If your Micro suddenly sounds dull, check the speaker grille for debris. The fabric can trap dust and small particles, which affects sound. Gently clean with a dry soft brush.
Should You Upgrade or Buy Which One?
If you already own a Gen 1 and it works fine, the upgrade is unnecessary. The extra hour of battery and Bluetooth 5.0 aren’t worth the cost for most people. If you’re buying new, the Gen 2 is the obvious choice since it’s the current model and usually priced the same as the Gen 1 was at launch. However, if you find a discounted Gen 1, it’s still a solid speaker—just be aware of the shorter battery and older Bluetooth. For a similar price, you might also consider competitors like the JBL Clip 4 (which has a longer battery and USB-C) or the Tribit StormBox Micro (which offers better value and stereo pairing). But the Bose SoundLink Micro remains one of the best-sounding ultra-portable speakers, and the Gen 2’s improvements, while minor, refine an already good product.
Cost and Value
At launch, the Gen 1 was $99.99, and the Gen 2 also launched at $99.99. In most regions, the Gen 2 has seen occasional discounts to around $79.99. The Gen 1 is often available refurbished for less, but note that Bose’s warranty (1 year) applies only to new units. Given that the Gen 2 adds a longer battery and better Bluetooth for the same price, it’s the better value unless you find a Gen 1 for under $60.
Frequently Asked Questions
Is the Bose SoundLink Micro Gen 2 worth upgrading from Gen 1?
No, not really. The improvements are incremental—a 20% battery increase and Bluetooth 5.0—but the sound and design are unchanged. If your Gen 1 still works, keep it. If you need a new speaker, get the Gen 2.
Does the SoundLink Micro Gen 2 have USB-C charging?
No, both generations use Micro-USB. This is a common complaint, as most modern devices have moved to USB-C. You’ll need to keep a Micro-USB cable handy.
Can I pair two SoundLink Micros for stereo sound?
Yes, both generations support Bose’s “Stereo Pair� feature via the Bose Connect app, allowing two speakers to play left and right channels. This works across generations, so you can pair a Gen 1 with a Gen 2.
Is the SoundLink Micro Gen 2 louder than Gen 1?
No, the maximum volume is essentially the same. The Gen 2 has a slightly improved DSP that reduces distortion at high volumes, but the overall loudness is unchanged.
How long does the battery last on the Gen 2?
Bose rates it at up to 6 hours at moderate volume. If you play at maximum volume, expect closer to 4 hours. Battery life also decreases over time as the battery ages.
Is the SoundLink Micro still worth buying in 2024?
Yes, if you prioritize sound quality in a tiny package and don’t mind Micro-USB. However, competitors now offer longer battery life and USB-C for the same price, so it’s worth comparing before you buy.
