JBL Professional 1 Series 104-BT Compact Desktop Reference Monitors with Bluetooth, Black, Sold as Pair, 4.5-inch Speaker

These are very fine desktop monitor speakers: Pros: They look awesome (I have the white pair, but they come in black as well). The design, while reminiscent of a giant suppository, stands out visually. They are SOLID. Everything about them feels very secure -- so probably, no rattling problems will occur. I doubt they are made of wood (not in that shape!) and whatever material they are using for the enclosure feels solid and firm. They sound very CRISP, CLEAR, and have a good thumping bass. The mid-range is a bit hollow at first, but as the speakers age and condition, this should work itself out. I think it is common to all NEW speakers and even headphones. They have plenty of volume, no problems there. They have excellent stereo separation, making a wide stereo sound stage, even when only a few feet apart. Hook-up was easy. They come with speaker wire, a power cable and a 3.5mm male to two RCA male (red and white) cable to connect to a computer. They also have 1/4" TRS type inputs, as well as Bluetooth, and a 3.5mm input jack on the front, as well as a muting headphone jack. I haven't tried the bluetooth, so I don't know how they perform, with it. CONS: None really. They could sound a bit warmer, but that will come in time through use. OVERALL: A great set of speakers at an affordable price for computer studio monitors. Great for mixing music and vocals into a video. I like them.

I know some of the stuff they sell here is cheaper. Don't send Chinese speakers back to AMAZON. They don't like it much, and we all pay more money because of it. A quick story. JBL was founded by James Bullough Lansing (1902–1949), an American audio engineer and loudspeaker designer best known for establishing two audio companies that bear his name, Altec Lansing and JBL, the latter taken from his initials. He still has plants all over, including here in Los Angeles, where he started his first company, End of story - back to review. You are an adult now. When you buy junk, you know it.

I’ve been living with JBL speakers for decades — long before Bluetooth, long before “desktop monitors” became a category. I still own a pair of JBL L-100s, and over the years I’ve had JBL-loaded guitar amps that taught me early what real sound is supposed to feel like. So let me be very clear: This review is not coming from a newbie. The JBL 104-BTs are small, yes — but they scream JBL in the best possible way. The stereo separation is stunning. The phantom center is dead-locked. Voices snap into place exactly where they belong, and instruments occupy real, intelligible space. Nothing is smeared. Nothing is hyped. Nothing is “helped.” The bass won’t shake your desk like a subwoofer — and that’s the point. It’s defined, present, accurate, and correct. You hear pitch, intent, and timing, not boom. This is reference sound at arm’s length. What impressed me most is how quickly these speakers disappear. That’s not an accident. That’s design philosophy. JBL doesn’t flatter recordings — it tells the truth. If you feed them something honest (Steely Dan, Bill Evans, orchestral work), they reward you with coherence and realism that’s frankly breathtaking for their size. Robert Pirsig wrote about Quality as something you don’t think about — it simply takes hold of you. That’s exactly what happens here. You stop analyzing and just listen. When a speaker does that, it’s doing something very right. Bottom line: JBL didn’t make a toy. They made a tool — one that reflects decades of hard-earned acoustic wisdom. These 104-BTs carry the same DNA as the great JBLs that came before them. JBL still rules the roost. Anyone who’s been in the trenches long enough will hear it immediately. Highly, unreservedly recommended.

These speakers are a really great value for the money. The sound is amazing for desktop speakers. My only complaint is the sleep function is hardcoded into them without a way to disable it. The only work-around is to ensure volume levels stay above a certain level to prevent the sleep function from kicking in. It’s a minor annoyance as it only happens once in a while that I have music on low enough that they will sleep.

So I bought these mostly for gaming, music listening and movies. Honestly, I think they're a bit overkill for that, but I don't consider that a complaint. I've seen some reviews regarding the bass response. I can see how that would be true if you're using them as they're intended or for listening to really bassy heavy music like House, EDM, Rap, etc. I'm mostly a rocker and haven't had the same experience. Your mileage may vary, but I've done a bunch of jazz, classic rock, metal and 80's pop... They sound great. The kick drum, bass guitar and low guitar tones are crystal clear. Like I said, they're a bit overkill for multi media use, but they have my full recommendation for anyone looking to step up like I was. I got tired of cheap, flat sounding speakers and I decided to spend a little more on a reliable brand. No regrets whatsoever. Mine do have the annoying startup noise a few other people mentioned and it does suck. I haven't figured out a way to disable it. Other than that, install was really easy and there's no blemishes on the speakers. I'm hard wired so I have no experience with the Bluetooth performance. I only removed one star because of the startup noise. It's really loud and unnecessary and I almost fell out of my seat the first time I turned them on, totally forgot about it.

I purchased these speakers a year ago to listen to music, and to watch YouTube and movies on my iPad and laptop monitor when working in my home office. These are fantastic speakers with a solid build! I decided to take a moment and write this review because I had never cranked up the volume before until tonight as I usually keep them at a low volume so I can concentrate. Well, man! I should be using these in my living room because they sound great cranked up. The bass, which is mild when the volume is low really punches when the volume is high. The sound is crisp and clear and music sounds really wonderful. NOTE: other reviews have complained about the loud chime when connecting to Bluetooth or switching between devices, however, I find the chime turns off if you set the “INPUT SELECT” to “ALL MODE.” And some have complained about the wires being loose but I have not experienced that. Everything works well and these speakers are heavy with a very solid build in my opinion. The tweeter is placed in the center of the speaker like KEFF speakers and I think that adds tremendously to the excellent quality of the sound. Bluetooth works great too! I highly recommend these for anyone who wants good bass and awesome clarity in their music.

These didn't connect to Bluetooth, sounded really cheap. These were a joke and not worth $14.99 let alone $140.00

These are just BARLEY good enough to not bother with the return process. Overall, the sound quality is very good in the mid range, and they live up to the promise of "studio monitors, catching quite a bit of depth if you're sitting directly in front of them. Once you wander away from the desk however, their punch noticeably decreases. The low range does not perform nearly as well as expected - my first thought when testing them out was "I guess I'm gonna need a subwoofer". The sound quality also suffers at higher volumes - there is a noticeable 'crackle" that occurs at a certain level before even maxing them out. ALSO - this is a nitpick, but it speaks to the overall quality/thought put in to these: the JBL "whooomp" startup noise is insanely low quality, as in, you can hear the bits in this thing. If you're selling "Studio Moniters" you'd think the first noise the end user hears on startup should be, I dunno, studio quality? Also, why are we even putting a startup noise into active/powered speakers? Silly. BIGGEST ISSUE - The Standby feature on these things is HIGHLY aggressive. They shut off after not time at all without audio input, and there's like a 10 second delay AFTER they register sound output before they actually kick on and start making noise. It may not seem like much, but it is wildly annoying. The 10 second delay is more a than enough to miss a "good morning" in a Teams meeting and leave you sitting there like a deaf idiot. TLDR: I went with the cheapest option, and got what I paid for

Muy buen producto, gran calidad y sonido.

I thought it will come with 2 type of power plug, but only 1 found in the box.

Excelentes, buenas bonitas pero no tan baratas, pero suenan muy bien, lo valen

Premetto che sono un amante delle yamaha msp, ho la serie 5 e la serie 3...cercavo una soluzione "portatile" compatta e performante e dopo decine di audio test online le ho preferite alle iloud micro (sembravano troppo bassose) e ne sono contento: paragonate fianco a fianco con le yamaha msp3 sembrano sorelle nella timbrica e nella copertura delle frequenze...ovviamente in potenza non reggono il confronto, ma sono più che sufficienti per ascoltare musica in casa o come monitor da scrivania! Davvero soddisfatto e assolutamente consigliate...se non siete amanti delle dinamiche bassose tipo krk...

Perfect for desc setup! Sounds clean and loud.
