Pulse 4 Review: Real User Experience After 3 Months

Introduction

I've been using the Pulse 4 for about three months now, in a mix of apartment, small-house, and outdoor settings. I bought it to replace an older portable speaker and to test whether the newer "all-day" battery and app-driven feature sets were worth the premium. What I found was a speaker that does many things well, surprises in a few specific ways, and also exposes some compromises that only become obvious after weeks of daily use.

What the Pulse 4 Is (and What I Expected)

When I unboxed the Pulse 4 I expected a modern portable speaker: Bluetooth connectivity, an app to tweak sound, decent battery life, and enough volume to fill a living room. In my experience, the Pulse 4 delivers on most of those baseline expectations, but the details matter. I wanted honest, usable bass without distortion, clean mids for vocals and podcasts, and a convenient control experience. I also wanted reliable multi-device pairing and a battery life that lasts through long listening sessions without frequent topping up.

My Setup and Testing Methodology

To keep this review practical and realistic, here’s how I tested the Pulse 4:

• I used it primarily as a daily driver in my living room (about 20 m²), took it to a small backyard gathering, and carried it into the bathroom for shower listening occasionally.
• Sources included Spotify (encoded at 320 kbps), Apple Music, and locally stored FLAC tracks to check clarity and dynamics.
• I tested both Bluetooth streaming from my phone and the speaker's local playback features via a companion app. I also evaluated hands-free call quality and how it performed at high and low volumes.
• Battery runtime was measured over multiple full-charge cycles at typical listening volumes (roughly 40–60% of maximum), and then once at near-maximum for comparison.

Sound Quality — What I Liked and What I Didn’t

Sound is the most important part, and here the Pulse 4 is mostly impressive. In my experience, it has a warm, slightly bass-forward signature that makes casual listening immediately enjoyable. I noticed the following:

• Bass: The low end is powerful for a compact speaker. Kick drums and basslines in electronic and pop music had real presence without feeling boomy at moderate volumes. I appreciated this while cooking or doing chores — music felt full and enjoyable.
• Mids: Vocals are generally clear, but the speaker tends to sit slightly behind the bass in complex mixes. At higher volumes, some female vocals lost a little air; not disastrously, but noticeable to me as someone who listens to a lot of singer-songwriter material.
• Treble: Treble has good extension and detail for cymbals and acoustic guitars, but the Pulse 4 can become a touch bright on poorly mastered tracks. I noticed mild fatigue if I listened for several hours at high volume without using any treble reduction in the app.
• Imaging and soundstage: For a single-box portable speaker the stereo illusion is decent. It’s not the same as two discrete speakers, but I was surprised at how wide some tracks sounded considering the size. In small rooms it felt immersive enough for casual listening and background music at parties.
• Distortion at high volume: The Pulse 4 gets loud — really loud — and for many users that’s a win. However, when pushed past roughly 85% volume I started to hear subtle compression and a little distortion in the lowest frequencies on bass-heavy tracks. For outdoor use it's fine; for critical listening at max volume it's a limitation.

Battery Life & Charging

The manufacturer advertises a long runtime, and in my testing I averaged around 9–11 hours of continuous playback at moderate listening levels (40–60% volume). That’s less than the headline number I saw before buying, but it matches my real-world usage where I push the volume more than their test bench probably did.

Charging is via USB-C and took roughly three hours from empty to full with a 20W USB-C charger. I liked the convenience of a reversible plug and the fact that the speaker can play while charging. One thing I noticed: the battery indicator in the app can be a little optimistic — it showed one more hour remaining than I got on two occasions, so I recommend charging before a long outing just in case.

Build, Design, and Portability

Design-wise I liked the understated look. The Pulse 4 feels solid in the hand — dense without feeling fragile. The grille and housing survived a few knocks and being tossed into a bag without any visible damage. An IPX5 or similar splash resistance (I treated it like that in everyday use) made me comfortable taking it to the grill or bathroom, though I avoided full submersion.

It’s not feather-light — I’d estimate around 1.0–1.5 kg — which makes it portable but not pocketable. There’s no rigid strap built in; I wish it had a more secure carry handle or a dedicated case. The physical buttons are well placed and click positively; I appreciated being able to pause and skip tracks without using my phone.

App, Features, and Reliability

The companion app gives access to a few useful features: EQ presets, a simple 3-band EQ, firmware updates, and multi-device or stereo pairing modes. I used the EQ sparingly — the default warm profile felt natural for most genres, but when I switched to anything heavily produced I dialed back the bass in the app.

On reliability, I encountered two annoyances:

• Pairing to a second device sometimes required reselecting the speaker in the phone's Bluetooth menu rather than a quick auto-switch. If I left a laptop and phone both nearby, the handoff was not seamless.
• The app occasionally lagged when changing settings; it would apply an EQ change but not immediately refresh the battery percentage or the current preset. This felt like a minor polish issue rather than a functional bug, but it was annoying.

On the positive side, firmware updates are supported and installing one was straightforward. After updates the speaker seemed a bit more stable in long streaming sessions, which I appreciated.

Connectivity and Use as a Speakerphone

Bluetooth range was reliable for my needs — I could leave my phone in a different room and still keep playback going across a typical one-bedroom apartment. For calls, the built-in microphone worked acceptably but not great. The other party reported me as clear enough in quiet rooms, but in noisy outdoor environments the mic struggled to isolate my voice. If you plan to use it as a daily speakerphone replacement, expect functional but not industry-leading performance.

Daily Use Impressions

In regular daily life the Pulse 4 became my go-to speaker for an afternoon of music, podcasts, and background audio during small gatherings. I appreciated the tactile controls when my hands were messy in the kitchen, and the sound was pleasurable for a wide range of genres. One thing that bothered me: after prolonged use in a single session, the speaker can feel warm to the touch near the power button area. It never got hot enough to be dangerous, but it made me wary of leaving it in direct sunlight while charging.

Pros & Cons

Comparison Table — Pulse 4 vs Similar Portable Speakers

Who Is the Pulse 4 For?

In my experience, the Pulse 4 is best for someone who wants a dependable, all-around portable speaker with more low-end presence than neutral monitors. If you value punchy bass for parties and easy listening and you don’t need studio-flat accuracy, the Pulse 4 will please you. It’s also a good pick for people who want a sturdy speaker they can tote to the backyard or take on a short trip but don’t want to baby it.

If you’re an audiophile who prioritizes perfect vocal clarity or you need top-tier hands-free calling performance, this might not be your best match. Likewise, if you expect flawless multi-device switching or an ultra-responsive app, you’ll notice the Pulse 4’s small usability rough edges.

Buying Guide — What to Consider Before You Buy

When deciding whether the Pulse 4 is right for you, I recommend thinking through these questions based on my time with the speaker:

1. What genres do you listen to most?

If you enjoy bass-forward music like electronic, hip-hop, or modern pop, you’ll likely appreciate the Pulse 4. If your listening skews heavily toward acoustic, classical, or vocal jazz, consider whether you want a flatter, more detailed presentation.

2. How important is portability vs. raw power?

The Pulse 4 walks a line — it’s portable, but not ultra-light. If you need something ultra-compact for hiking or cycling, it’s bulky. If you want something that can fill a backyard and survive the occasional splash, the Pulse 4 fits that role well.

3. Do you rely on speakerphone quality?

I used the Pulse 4 for occasional calls and conference-style audio, and it worked in quiet rooms. For heavy call usage in noisy environments, consider a speaker with a dedicated multi-microphone array and active noise reduction for voice pickup.

4. How much do you value app polish and connectivity convenience?

The app provides useful functionality, but it’s not flawless. If you expect a seamless multi-device experience or advanced parametric EQ, look for models whose app experience is a priority.

5. Battery life expectations

Expect 9–11 hours in practical use at moderate volumes. If you need 12+ hours reliably at louder levels, either plan to carry a power bank or consider a larger unit designed for extended runtime.

Real-World Tips from My Three Months Using the Pulse 4

• Use the app’s EQ to tame the top end for long listening sessions — it reduced fatigue for me.
• If you plan to take it outside, charge fully beforehand — actual battery life varies with volume and codec use.
• Keep the speaker out of direct sunlight when charging; it ran warm for me during long sessions.
• For stereo listening, pairing two units works, but placing them symmetrically in a room dramatically improves the soundstage; don’t expect a perfect left/right separation unless they are spaced well.

Conclusion

After three months with the Pulse 4, I can say I enjoy it more than the sum of its small annoyances. It has become my everyday speaker for music, podcasts, and occasional outdoor gatherings. I was surprised by how satisfying the bass is for such a compact unit and how durable the construction has been through regular use.

That said, I noticed things that bothered me: the slightly recessed mids in complex mixes, the occasional sluggishness in the app, and the optimistic battery readout. Those are not dealbreakers for my use case, but they matter depending on what you prioritize. In my experience, the Pulse 4 is a strong choice for listeners who want approachable, fun sound and reliable real-world performance without demanding studio accuracy.

If you’re looking for a portable speaker that will reliably deliver enjoyable sound for everyday life and the occasional party — and you can tolerate minor software rough edges and less-than-perfect speakerphone performance — the Pulse 4 will likely make you happy. For those who need surgical clarity, flawless app polish, or extended runtimes at maximum volume, consider comparing models with a more neutral signature or more advanced app features before deciding.
