Customer Ratings & Reviews

I bought the JBL Go 4 Portable Bluetooth Speaker in purple on September 22, 2025, and it’s been a fantastic addition to my tech lineup. For such a compact speaker, the sound quality is outstanding—clear highs, solid mids, and surprisingly deep bass for its size. It’s perfect for streaming music, podcasts, or even taking calls. Setup was a breeze, and the Bluetooth connection is reliable with no dropouts. The battery life easily lasts through a full day of use, and the vibrant purple color adds a fun pop to any space. It’s lightweight, durable, and easy to toss in a bag for travel or outdoor use. If you’re looking for a portable speaker that delivers big sound without breaking the bank, the JBL Go 4 is a winner. Highly recommend!

I got this thing to ride my bike with my kid and have music playing. Mission accomplished... but that's not all! One, my kid loves it. At 15 months, she can operate this speaker, so if you can't, she's smarter than you. Let that sink in. Meanwhile I realized that if you have more than one of these you can chain them and make your own surround sound... so I'm probably getting another soon. Definitely a worthy investment. Oh and it's waterproof to like 62 meters.

Sound quality is great for the size and price. Super compact and light. The battery lasts a long time and seems to recharge quickly.

I am extremely impressed despite its small footprint, it offers clear sound with a decent amount of bass, making it great for casual listening. The battery life lasts around 5 hours, perfect for short trips or daily use. It’s water and dustproof, making it ideal for outdoor activities. Connectivity is straightforward, with quick Bluetooth pairing. For its price, the JBL Go 4 provides great value, offering solid performance in a tiny, portable package. Highly recommended.

JBL nailed the Portability : Performance : Cost ratio with this discreet bluetooth speaker! 9/10 The sound is surprisingly loud and full-bodied enough for a group of friends of about 8-10 persons to all share in the audio experience. The battery life is respectable for the size and the quality/durability is pretty fantastic! I highly recommend!

It’s not heavy on bass, but that’s expected from such a compact speaker. Great for casual listening, podcasts, and acoustic music. Battery: Lasts about 6–7 hours at medium volume, which is more than enough for daily use. Charges quickly via USB-C. Build Quality: Very solid and portable. It feels durable, and the waterproof and dustproof design makes it perfect for outdoor use. Buttons are responsive and well-built. Overall: For the size and price, this speaker is a great deal. If you’re looking for portability and reliable quality, the JBL Go 4 won’t disappoint.

I recently got my hands on the JBL Portable Speaker 4, and I have to say, I’m impressed. This speaker packs a punch in terms of both sound quality and portability. The audio is rich, with deep bass and clear highs, which is pretty surprising for something so compact. It's powerful enough to fill a medium-sized room, making it perfect for both indoor and outdoor use. The battery life is another highlight. I get about 12-15 hours of playtime on a single charge, depending on the volume level, which makes it ideal for day-long outings or parties. The IPX7 waterproof rating is a huge plus—I’ve taken it to the beach and by the pool without worrying about splashes or a little rain. Pairing it with other JBL speakers is easy with the JBL Connect+ feature, which lets me link up multiple speakers for an even more immersive experience. The only minor drawback is that it could take a little longer to charge fully, but the long battery life more than makes up for it. Overall, the JBL Portable Speaker 4 is worth it if you're looking for a reliable, durable, and great-sounding portable speaker. Highly recommended!

Great sound for such a small speaker. Love the sound, look, and size. In fact, because you can synch three of them, I went back to the store to buy two more of these speakers. Now, I have stereo music playing in my entire apartment.

The JBL Go 4 is surprisingly powerful for such a tiny speaker! Super compact, waterproof, and perfect for on-the-go use. The sound is clear with punchy mids—great for podcasts, music, or outdoor use. I love the app's EQ options and easy Bluetooth pairing. Battery life is solid, though not as long as bigger models. Highly recommend if you want portability and crisp audio in one tiny box!

The quality of this little Bluetooth speaker is great. Battery life is excellent. I love the loop which allows me to attach it to a clip.

I bought one of these and like it so much that I bought a second. It’s easy to pair, has excellent battery life, and sounds good. Small, very portable, and seems almost indestructible.

More convenient to carry around, sound quality is amazing and has a durable battery life.

Was looking for a simple Bluetooth speaker and this is perfect. Super easy to connect, large buttons on the side considering how small it actually is. Good sound quality and comes with a little hook so you can hang it. Love it!

This little speaker has been easy to pack, produces quality sounds, and works well with all my blue tooth devices

Works well has great sound and is very mobile and small enough to take anywhere. Took it on vacation with me to the Virgin Islands and used it every day at the pool. Great to use anywhere good sound and batteries work well.

This speaker is awesome great for outdoor working and has a long battery life. Would recommend if you need something loud but small for anywhere.

The device's extended battery life, superior sound quality, and robust durability are highly commendable, and the competitive pricing further enhances its appeal.

The sound is perfect, good volume, small to take anywhere.

The pros of this product is that is very portable. Has a very good sound quality an option to use an equalizer on the app and you can connect the same speaker to make stereo or use the auracast to connect other auracast jbl speakers the cons of the speaker is the seven hour battery life the lack of bass and does not support AAC format just SBC. If you are looking for a portable compact speaker that replaces your phone speakers with a very good sound quality and customizable EQ I would highly recomend it.
