Marshall Stockwell II Black and Brass Portable Bluetooth Speaker

Marshall Stockwell II Portable Bluetooth Speaker - Black and Brass

The Marshall Stockwell II Portable Bluetooth Speaker is a fantastic portable speaker designed primarily for music lovers who live life on-the-go.

Because of its portability and the array of features it offers for its size, it is an excellent choice for outdoor parties, picnics, or any situation where high-quality mobile music is required.

With an impressive battery life of 20+ hours, it provides enough playtime for a full day’s worth of activities on a single charge.

Plus, with its Bluetooth 5.0 technology, you can play music from any Bluetooth device within a 30 feet range, giving you all the flexibility and convenience you need.

What sets the Marshall Stockwell II apart from other portable speakers is its True Stereophonic, a unique form of multi-directional sound technology from Marshall.

This ensures that every spot is a “sweet spot”, delivering an absolute 360° sound experience, adding depth and immersion to your music.

Also, the speaker comes with a handy carry strap inspired by a guitar which I found amusing and handy for travel.

The Marshall Stockwell II is designed to bring the classic Marshall performance to a small, transportable format.

It has a rugged, silicone exterior and steel metal grille that make it incredibly durable – perfect for those who are constantly on the move.

Moreover, the speaker boasts an IPX4 water-resistant rating, making it capable of withstanding splashes of water, so little accidents won’t bring the fun to a halt.

Another standout feature is the multi-host functionality, which allows for easy connection and switching between two Bluetooth devices.

This means you and a friend can seamlessly take turns in playing your favorite tunes.

The top panel of the speaker features analog control knobs for bass, treble, and volume, allowing for fine-tuning of sound to your exact preferences.

The ability to control bass and treble is something I appreciate, as it lets me adjust the sound depending on the genre of music I’m playing.

When it comes to quality, I can assure you that the Marshall Stockwell II certainly punches above its weight. Its superb construction guarantees a durable build, and the top-notch sound quality is beyond what you would expect from a speaker of its size.

The battery life is quite remarkable – offering up to 20+ hours of playtime on a single charge. And with its ability to get a full charge in just 5 hours, you’re never too far from enjoying your favourite music.

If you’re in a hurry, a 20-minute charge can provide a staggering 6 hours of playtime, which I find really impressive.

Finally, it’s vital to weigh the good against the bad to get a well-rounded perspective of the product.

  1. 20+ hours of continuous playtime – This makes it an ideal companion for a full day out.
  2. Bluetooth 5.0 technology – Provides a wide and stable connection range.
  3. True Stereophonic – Offers a unique multi-directional sound experience.
  4. IPX4 water-resistant rating – Can handle water splashes.
  5. Quick Charge – Just 20 minutes of charging gives you 6 hours of playtime.
  6. It doesn’t have an integrated microphone for calls.
  7. It’s a bit pricey compared to other portable Bluetooth speakers in the same range.

The Marshall Stockwell II Portable Bluetooth Speaker truly stands out in the market with its unique sound technology, impressive battery life and rugged construction.

If you value sound quality, long playtime and durability in a portable Bluetooth speaker, this might just be the one you’re looking for.

Product Comparison

When choosing a portable Bluetooth speaker, several factors come into play.

From the sound quality and volume, battery life, durability, and unique features, the perfect speaker for you depends on your individual needs and preferences.

As such, I will attempt to break down the specifications of four popular products:

  • Marshall Stockwell II Portable Bluetooth Speaker
  • Bose SoundLink Flex Bluetooth Portable Speaker
  • Bose SoundLink Revolve+ (Series II) Portable Bluetooth Speaker
  • JBL Boombox 2 Wireless Bluetooth Streaming Portable Speaker

Marshall Stockwell II

The Marshall Stockwell II stands out for its durable silicone exterior and steel metal grille, boasting an IPX4 water-resistant rating.

It offers an impressive 20+ hours of playtime and a quick charge time, which adds to its portability.

One unique feature is its multi-directional sound and the ability to fine-tune your sound with analog control knobs for bass, treble, and volume.

Bose SoundLink Flex

The SoundLink Flex by Bose is designed for outdoor use, meeting IP67 standards for a waterproof speaker.

It offers up to 12 hours of life per charge and the charging time is approximately 4 hours.

This speaker automatically adjusts the sound depending on its orientation, and it can be controlled through the Bose Connect app.

Bose SoundLink Revolve+ (Series II)

This Bose model offers up to 17 hours of battery life and superior sound quality because of its design to deliver a consistent 360 sound.

It is also dust and water-resistant (IP55 rating) and comes with a built-in microphone for calls and interactions with default voice assistant.

JBL Boombox 2

The JBL Boombox 2 is all about delivering big bass and extended playtime. Offering up to 24 hours of operation on a full charge, this beast also has a built-in power bank to charge your devices.

Conclusion: The Final Verdict on Portable Bluetooth Speakers

Among those considered, the Marshall Stockwell II Portable Bluetooth Speaker – Black and Brass, the Bose SoundLink Flex Bluetooth Portable Speaker, the Bose SoundLink Revolve+ Series II Portable Bluetooth Speaker, and the JBL Boombox 2 Wireless Bluetooth Streaming Portable Speaker all exhibit their unique strengths and a few minor drawbacks.

Starting with the Marshall Stockwell II, it showcases excellent sound quality with its unique Black and Brass design making it an aesthetically pleasing portable speaker.

However, it lacks some advanced features that other models boast, such as waterproofing and dustproofing. So, while it’s perfect for indoor use, it may not be the best choice for outdoor adventures.

Next up is the Bose SoundLink Flex Bluetooth Portable Speaker, a robust and waterproof option that can handle travel and outdoor use with ease.

It might be a bit on the pricier side, but its solid performance and durability make it a worthwhile investment for those who love taking their music on the go.

The Bose SoundLink Revolve+ Series II brings another layer to wireless water-resistant speakers, adding a long-lasting battery and a super convenient handle!

On the flip side, it’s not fully dustproof, which could shorten its lifespan if used frequently in dusty environments.

Lastly, the JBL Boombox 2 takes the cake when it comes to a marathon playtime. Its dustproof and waterproof design, along with a whopping 24 hours of playtime, makes it an excellent companion for long outdoor ventures.

But be aware that it’s heavier than the others, which can be a challenge for those who prioritize portability.

Audience recommendation

While all the speakers have their special flavor, I’d recommend the JBL Boombox 2 to anyone who spends lots of time outdoors—campers, beachgoers, or hikers.

The long battery life and durability make it a winner for these pursuits.

On the other hand, those who prefer a more compact and stylish solution for indoor or light travel use might find the Marshall Stockwell II more to their liking.

The Bose SoundLink Flex and Revolve+ offer a great balance for people who need a solid, durable speaker that offers decent battery life and is friendly for both indoor and outdoor use.

In the end, it’s about your specific needs and preferences. Weigh the features of each speaker against your lifestyle to make the perfect choice. Happy listening!
