HiVi-Swans OS-10 HiFi Stereo Speakers, Bluetooth 5.0 Active Computer Bookshelf Speakers - 4'' Dynamic Woofer, Powered Desk Speakers 62w RMS with Touch Control for PC/Phone/TV - Black

Update: Moved these to my daughter's. Set her up with a Wiim streamer and these little OS10s and she couldn't be happier. Before letting them go, I decided to place them where my TV goes for fun and man, these little speakers really pump out a lot of sound for their size. These make great first speakers and are extremely versatile. You can use them for your tv/theater set up, on your desk, or on a bookshelf. Loud enough to be your main speaker setup and small enough to put into other rooms. I uploaded a video of these things on top my mains. The recording probably doesn't do it justice... but they really put out a nice full sound. My listening area is around 500 sq ft and it has absolutely no problem filling the room with sound. Highly recommend. Original Review: They’re nice little speakers. They feel a bit plasticky and cheap. But the cloth shell helps elevate the look over other small speakers. They sound nice. They can be a little boomy in the bass on the desk and next to a wall. Elevating them really helps. Good little set of speakers. I run them through a usb preamp and they work great. The volume and input controls are a little annoying so it’s much nicer to use the knob on the preamp. I don’t like capacitive touch buttons. They are too sensitive and make an annoying light. I had to cover them with electrical tape. Overall, I’m pretty happy with them. Music sounds very good and they have plenty of oomph for gaming

These speakers are breathtaking. I've tried them in two different setups: near-field listening on my desk and on top of ELAC bookshelves with speaker stands. To get the best sound, I recommend placing the speakers on stands and giving them at least 2-3 feet of space from the wall for the rear ports to breathe. For near-field listening, they have detailed and clear mid-range. The treble can be a little fatiguing at this distance, but that can be solved through equalization. Despite the small size of the speakers, the low end is surprisingly good. 80Hz-100Hz is punchy and detailed. 60Hz-70Hz is where it starts to drop off, but it’s still audible at this distance. 40Hz-59Hz drops off harder and is much less audible. Below 40Hz is pretty much non-existent. But what more can you expect from little 4” woofers. Overall the sound signature is quite flat, which I like. As far as imaging and sound stage they are very impressive, they are quite wide with instruments and vocals that don't sound like they're coming directly from the drivers. When placed on speaker stands, the extra room and distance greatly improves the sound quality, making the speakers sound even more impressive. The treble fatigue is reduced, and the low end is improved. The imaging and sound stage are greatly enhanced, and the speakers truly sound massive. Simply incredible. I've connected the speakers in three ways: RCA from my ifi Zen DAC V1, S/PDIF optical from my PC, and Bluetooth. How do each sound? Well, as far as purity, technically optical should sound the best as these speakers use a DSP crossover. So sending them an analog signal is going to get converted back to digital, then the crossover will be applied, then the speaker's internal DAC will convert them back to analog. Personally, I hear no difference between RCA and optical on these speakers. Bluetooth sounds just okay, I believe it's using the AAC codec, though it could be aptX, so it's not going to be as good as LDAC or other Hi-Res codecs. I encountered an issue where the speakers would emit a low-frequency hum if they were turned on and set to the AUX input while the DAC was off. However, since I keep my DAC on all the time, this won't be a concern for me. If this humming sound bothers you, you might want to consider using optical, coaxial, or Bluetooth instead. One thing that would make these speakers even better is if they had an LFE output on the speakers for a subwoofer. But if you use RCA, you could buy a splitter, pass one to the speakers, and the other to a powered sub that has line in. You would need to have a DAC that can act as a preamp otherwise you would have to change volume on the speakers and the sub which would be annoying. My reference speakers are the ELAC Uni-Fi 2.0 UB52 and Emotiva Airmotiv SE12 with the topping E30 DAC and Yamaha as301 integrated (I wasn’t using the sub for the comparisons as it wouldn’t be fair.) The OS-10s are impressively close in terms of sound quality, with nearly the same imaging, sound stage, and detail as the ELACs. The 100Hz-130Hz range on the OS-10s is actually cleaner than the ELACs. I blind A/B’d between the two and was stunned as there is very little difference. If the ELAC’s are 100% in terms of overall quality then the OS-10’s are 97%. It’s unreal. As Zeos said in his video, if these cost $400, they would still be worth every penny. Note: If you prefer neutral sound, you'll love these speakers. However, if you're a bass head, these speakers may not be for you as it's difficult to connect a subwoofer. My overall ratings based on the price: Sound quality: 10/10 Imaging: 9/10 Vertical off-axis Imaging: 9/10 Horizontal off-axis Imaging: 8/10 Sound stage: 9/10 Instrumental Separation: 9/10 Low end: 9/10 Mid range: 10/10 Treble: 9/10 Features: 8/10 (LFE out would make it a 10) Remote: 8/10 (It works, but you need to point it within 10 degrees of the IR receiver) Value: 10/10 Build quality/design: 10/10 Overall a 9/10, but considering the sheer value, they are getting an easy 10/10.

First off, reviewing a second set. First set came in and after hooking it up, the left speaker's woofer was not making sound. Messaged Swans on here for support and after explaining and recording the issue, ruling out loose wires or signal source, they had the speakers replaced under warranty. The new set arrived promptly and worked as they should! The good: they look nice; they're not huge, but they're not tiny. The sound is clear and clean for powered bookshelf speakers in this budget range but I haven't really pushed these through formal tests or anything. Just been listening to music from a TV and a record player and a phone for a few days, and a few episodes of Fallout on the TV, and they beat my old soundbar by a good margin. Of course sans a sub there's a little less punchy bass but I specifically didn't want thumping bass for my bedroom or a sub on the floor. These were for sitting in bed in the evening and enjoying some tunes or shows while other people are asleep. My main issue (disregarding the initial defective set) is that these don't have very granular volume control which IMO should be critical for powered speakers that are taking on volume management duty. These are fine TV speakers if you are listening at medium or higher volumes during the day. But if you're trying to turn it down for evening listening you have essentially one volume level of 15% as your only option. And if it's not quite loud enough, the next step is around 25%, then maybe 40% and by then that's as loud as I use even during the day, even with an AC going. I've never needed to push them much beyond that. They will go there. (Also, I ran into this same granularity regardless of using optical control via the TV, or bluetooth and using the speaker remote.) Now I got a new phono-amp with a volume dial for my record player, so I should get a little more nuance with records at least. If I knew of this peculiarity ahead of time, I am not sure I would have ordered these for my TV setup and use case. I'm certainly glad to have them for the record player though, and will definitely keep using them! If you are not worried about primarily using them down at the low end of the volume range then I recommend them!

Klingen gut. Vielleicht ein kleines bisschen auf der teuren Seite, aber das passt schon so in etwa. Ein Sub-Out wäre allerdings noch extrem hilfreich gewesen.

Actualmente tenia los edifier 1280db los usaba con un preamp de bulbos fosi pero no notaba mucha diferencia en calidad, después de investigar bocinas calidad precio encontré estas por reseñas en YouTube, y me lleve una total sorpresa, la calidad y potencia comparado con las edifier es brutal, las recomiendo totalmente principalmente para dar un paso en la audiofilia.

I really loved the sound from these speakers. Love the fact that they have all kinds of inputs to play audio. I didn’t notice much drop in quality through Bluetooth either. I’m using Spotify and tuning up the equalizers in the Spotify, it’s working well to fine tune the sound to my liking. Out of the box sound is also very well balanced. They seem to have a quality built. Haven’t noticed any hissing or rattling yet. I could not expect a better speaker for this price. The areas of improvement: There is no subwoofer output that makes connecting a subwoofer a bit tricky but not very hard or expensive. I will try a powered subwoofer on it eventually. My other complaint is that they are not offering other speakers in the Canadian market, which does not induce much confidence in the buyers mind. Other than that, it’s a great product and I give it 5 stars.

die boxen sind im prinzip gut zum hören lauter musik für leise töne oder als lautsprecher für fernseher eher ungeeignet, weil bei leisen tönen die stimmen dumpf und unklar werden.

Muy buenos altavoces. Son los primeros que uso con DPS y quedé impresionado por la calidad de audio. Lo único que me gustaría es que tenga la opción de controlar el bass y treble. Recomiendo siempre usarlo con música digital.
