Overview:
Yes, this 5W pocket speaker by Sony is impressive—and if you haven't guessed it yet, we’re talking about the SRS-XB01. Despite being a small mono speaker with just 5 Watts of power, it delivers results you might not expect. Read our blog to find out why.
The SRS-XB01:
The speaker was launched by Sony in India on 1st October 2018, so it's been about 7 Years since its official launch. Sony made it available in 6 different colours so I doubt you will have trouble with finding your pick. Its sale price was Rs. 2,590 and often sold lower at sales, making it an entry level branded speaker. Sony highlighted many of its amazing features as below:
Powerful sound with EXTRA BASS™
Splash proof supported with IPX5 rating
6 hours of Battery Life for non-stop music
Light weight and easy to carry with strap
Easy connectivity with Bluetooth®
My Review:
Build & Design:
Well, as Sony claims the speaker is quite light weight and is pocket friendly, means you could easily carry it on the go. The Design is quite sleek and minimal (I have the black colour), It has two indicators behind the mesh, Blue for connection status and red for low power and charging indication. On the top you have 4 control buttons which are:
Play/Pause (Receive/Answer Calls)
Power (Hold for Pairing Mode)
Volume Down
Volume Up
On the right side you get some ports which are:
Audio In (3.5mm)
Micro USB port (For charging)
Reset Button
This speaker also has the IPX5 Rating, which means it is splash and ingress resistant. Overall, the Build Quality feels sturdy, Design is quite minimal and the ports are sufficient, although you would usually find a USB A port on Bluetooth speakers, this one doesn't have that, it can be a bummer for those who use a USB A Flash drive for music.
Sound Quality (What you came for):
Okay, I've been using this speaker for a few months now with my laptop, mostly to listen to music and here what I have to say. Firstly, my laptop speakers are already quite good, which support Dolby Atmos. Hence, I consume most of my content via my laptop speaker. The space where most laptop speakers lack including mine is Bass and distortion at loud volumes.
This is where the XB-01 comes in to save the day, whenever I need to listen to songs, I quickly connect it to my PC via Bluetooth (and it connects in less than 3 seconds) and it provides amazing Bass to songs and almost zero distortion at high volumes. I found that you would get great music quality when playing high quality music files i.e. 320 Kbps. The loudness and Bass really surprised me considering the spec-sheet states only '5W', so let's deep dive on how Sony did this.
Extra Bass with Passive Radiator:
The Sony SRS-XB01 achieves its signature 'Extra Bass' by utilizing a passive radiator, which is essentially a 'drone cone' that produces sound without using any extra battery power.
It is like having 2 speakers in a single body:
The 37.5mm Active driver which actually produces the sound.
The passive radiator which is a speaker diaphragm without a magnet or voice coil.
As the SRS-XB01 is a sealed unit, when the active driver moves back and forth to create sound, it changes the air pressure inside the small chamber. Instead of that pressure being trapped or escaping through a hole (like a port), it forces the passive radiator to vibrate in sympathy. This effectively doubles the surface area pushing air out of the speaker, allowing it to produce frequencies much lower than a single small driver could achieve on its own.
Achieving Bass Without "Chuffing" (Low Distortion):
Many small speakers, manufacturers use a bass port which is a literal hole or tube. However, at high volumes, air rushing through a tiny hole creates a whistling or huffing sound called port noise or chuffing. Since the passive radiator is a solid diaphragm, there is no air-to-surface friction. This eliminates wind noise entirely, ensuring the bass remains clean even when you crank up the volume.
The air inside the sealed box acts like a spring. This air spring helps control the movement of the active driver, preventing it from shaking uncontrollably (oscillating) at high volumes, which is a common cause of audio distortion in cheap speakers.
Summary of Sound Quality:
Overall, I love this speaker for music. However, while it’s my go-to for songs, I found myself switching back to my laptop's built-in speakers for movies and TV shows. Even though the XB-01 has superior bass, the stereo separation on my laptop provides a much more immersive 'surround' feel that a single mono speaker simply cannot replicate.
The speaker produces consistent sound quality across both my phone and laptop. It’s worth noting that both devices have Dolby Atmos enabled, which likely helps the XB-01 perform at its best. Do check out the sound samples I’ve uploaded below.
Audio Samples:
Audio is being played via Bluetooth from a Windows PC with Dolby Atmos enabled. Volume is set to about 85%.
Connectivity & Battery Life:
As Sony claims the connectivity feels super-fast, even with Bluetooth 4.2 in this time period. Pairing takes about 10 seconds or less and connecting thereafter takes less than 3 seconds always. Sony claims a Battery Life of 6 hours which may seem less, but I would love to say that I feel I got quite more than that. Now this can be because I used the speaker on and off, for about 10-15 days in a month, each day's usage lasting about an hour, and I didn't have to charge it even once in that month.
So yes, the battery life is definitely more than 6 hours, but once again this highly depends on the usage patterns, however we can say that the battery optimization is quite good and the battery hasn't degraded. I haven't used the Line In port so I can't comment on that, neither have I used the Microphone much. I'm not sure if many people even use the mics on the speakers; I tried recording my voice on a voice recorder (On windows) and the pitch of the voice was changed for some reason. Windows does show that the mic quality being 1 Channel, 16 Bit and 16Khz (Tape Recorder Quality).
Final Verdict:
Overall, this is a great pocket speaker even in 2026. It's good for those who want a speaker for daily music sessions, its sound is enough for a small room party I'd say. I've uploaded Sound test videos on the videos section of this Blog, do check them out. It has a good battery life, only disadvantage being it charges via Micro-USB, I did have to take the trouble to get a Micro-USB cable in 2026 to charge this speaker. Connectivity is perfect.
This speaker is highly recommended for Students who want a speaker on their desk, Travellers who want portable and rich audio on-the-go. Being a student, this speaker is a permanent member of my desk setup beside my laptop.
However, if you see this speaker for sale, anywhere for more than Rs. 1000, Don't go for it. Yes, as I said, it's a great speaker but not worth buying for more than this price in 2026. Sony has also released its successor the Sony XB-100 in 2023, which is a massive upgrade.
View the below table to see the comparison between the two.
Feature | Sony XB-01 (2018) | Sony XB-100 (2023) |
Sound Tech | Passive Radiator | Passive Radiator + Sound Diffuser |
Durability | IPX5 (Splash and ingress resistant) | IP67 (Water and Dust Resistant) |
Battery Life | 6 Hours | 16 Hours (166% Upgrade) |
Charging Tech | Micro-USB (Outdated now) | USB Type-C (Modern) |
Connectivity | Bluetooth 4.2 | Bluetooth 5.3 (Better range and stability) |
Mic Quality | Basic (Close proximity) | Echo Cancelling (Better for phone calls) |
So maybe if you get it below Rs. 1000 and it matches your needs; you can get it. It is not recommended for any medium group events or such stuff where this speaker may lack. So, in the end I'm impressed with Sony's Quality engineering on this speaker. Please do note that I'm not a Sound Engineer or Audiophile, so this review is solely based on personal experience and research.
Thank you for Reading my Blog, do check out the sound sample videos I have uploaded.
