Nobsound NS-15G Bluetooth Amplifier, Mini 200W Amp, TPA3116 Chip, HiFi Stereo Class D 2.0 Channels, with Power Supply

I have FIVE of these little amps powering 10 ceiling speakers in my house. Each connected to an Amazon Echo Input providing multiroom audio via Alexa. I had initially planned to expand my gen 1 Sonos setup which cost me over a grand, but Sonos lost me when they threatening to brick the gen 1 stuff. I sold it all and won't be buying any more! Not only that, I find it ridiculous at how much Sonos charges for their amps. £600? No thanks! I've basically saved myself £3k. Each zone in this setup costs me £70 (£350 overall). Okay, so Amazon hasn't fully matured its multiroom audio capabilities to fully compete with Sonos. After all, it is a cloud-based platform, whereas Sonos is mesh-based (Sonosnet), giving them the upper-hand. With that said, Amazon Alexa / Echo still functions reasonably well for multiroom audio. There are just a few issues that I've outlined below. + Speaker groups have no independent volume control (just group control). You have to disconnect from the speaker group, connect to the Echo that needs volume adjustment, then reconnect to the speaker group. Speaker groups cannot be chosen on the fly while you're playing music. You have to set your groups up first, give them a name, and then you can start playing music through that group. + Want to play different music in each room? Both Spotify and Amazon Music requires a family subscription to play different music on different devices. You can, however, have Spotify playing on one device (through Spotify connect) and Amazon Music playing on another. Amazon Music supports Apple Music, Deezer, and TuneIn, but these serves can't be played independently. One more option: You can use BLUETOOTH on the amps! So you can effectively play 3 songs on 3 different Echo's. Edit: you can play different music on different devices through Amazon music but I think you need Prime Membership to do this. +Want to play local files? Unfortunately, there is no support for playing local files on Amazon Echo devices because they are cloud-based. However... BLUETOOTH is again the savour. Just remember to rename all amp Bluetooth names to the correct room, so you can identify them easily. These amps have Bluetooth 4.2 built-in, Nobsound also sells the Bluetooth 5 version, which supposed to provide better range; however, I find these have adequate range to cover every room of my Dorma Bungalow (placed in unconverted loft space). So how do these amps perform? Well, I'm extremely impressed with them... that's why I bought 5!. Audio quality is much better than the old Sonos ZP120 which had a pitiful output of 50w per channel. These amps provide 100w per channel - more than enough to power my speakers to uncomfortable volumes. There are also BASS and Treble controls which work really well. I have the volume and bass set at 2 o'clock and the treble at 12 o'clock. I have one amp connected to a cheap 2-way speaker switch allowing me to link bedroom speakers and bathroom speakers without the need of another amp. For those wondering: My speakers consist of: 1 pair of Yamaha NC-IS800 8-inch ceiling speakers (Bedroom) 2 pairs of AmazonBasics 8-inch ceiling speakers (Kitchen and Bedroom) 1 Lithe Audio LASS65 6.5-Inch Stereo Dual Tweeter Ceiling Speaker (Bathroom) 1 pair of Adastra Slimline 6.5-inch ceiling speakers (Bedroom) 1 Adastra Stereo 6.5-inch Dual Tweeter Ceiling Speaker (Bathroom) You're probably thinking... a bit rubbish. I admit, the Adastra's are a bit pants (but mainly because I've not installed speaker hoods yet). The AmazonBasics are spectacular - everyone comments on how amazing they sound. The Lithe Audio speaker is great and the Yamaha's are easily the best. (I use another 4 Yamaha's in my 7.1 Dolby ATMOS system - they sound incredible). Other reviews have mentioned interference. One scenario that you will get interference is if you have a multitude of wireless devices near the amps inside your server cabinet. You'll know it's caused by wireless as you will hear a very low pulsing static sound coming through the speakers. To irradicate this, you need to ensure any wireless devices are placed outside of your cabinet. I did initially make this mistake by having a wireless router, Tenda mesh Wi-Fi and all echo's inside the cabinet. I've since disabled Wi-Fi on the router, placed the primary Tenda node and all echo devices outside of the cabinet and my speakers are now completely silent. I've seen others attaching echo inputs to the top these amps, I would not recommend this as you will likely get interference. Other interference can be caused by poor quality speaker wiring. I've installed premium-quality QED QX16/4 or QX16/2 speaker cable throughout my house. The other, often overlooked thing, is these use a hardware on/off toggle switch which means I've been able to add smart switches to schedule them to turn off and on. Overall, I love these amps! They're great value, provide plenty of output and most importantly, sound great!

Well made. Well worth it. Easy to set up with or without Bluetooth. Excellent power and sound. The control knobs could be better to use, they aren't as smooth to turn as they should be, but thats me being fussy. I would strongly recommend this amp. I have not seen or heard any products of similar function so I am unable to provide any comparisons. That said this amp surpasses what I was expecting bigtime. I used it in my garden with my house speakers and it was time to party.

Fairly good sound, better than the cheapo £12 mini amps that are around 20W RMS. Still messing around with the bass and treble to give a proper review of the quality. I feel like it's got a lot of power though. Bluetooth reception could be better (though it's probably my old laptop that's bad). NOTE: remember to plug in the adapter into the amp before switching it on at the mains, otherwise some small sparks will come from the adapter port at the back of the amp. Honestly not a big problem but should probably be rectified in future models. The case is good quality, and it all feels pretty solid. Though some of the nobs sway from their axis as you turn them. No big deal. The speaker connections are well made and work well. The LED is just bright enough not to be annoying.

I bought this to power a pair of JBL Control One speakers in a small game room setup. I have a number of game consoles hooked up to a TV via a HDMI switcher and RGB SCART Switcher. Both of the switchers have RCA audio outputs. These outputs are taken to a 3 input RCA audio splitter (https://www.amazon.co.uk/gp/product/B000KVODHA/ref=ppx_yo_dt_b_asin_title_o05_s01?ie=UTF8&psc=1), then from there fed into the RCA inputs of the Nodsound mini amp. The output from the amp is really loud and punchy. REALLY loud for such a tiny little device. There are basic treble and bass controls for EQ, which suits my needs. I keep treble at '12 O'Clock' and boost the bass a little to '2 O'Clock'. Really impressed with the power of the output. It's not audiophile Bang And Olufsen quality, but it's fantastic for the price and for the size. A neat solution for space-saving setups. Just a pity about the name. Nob Sound? C'com!

This is the best little amp i have ever brought. Used to power 2 x 120w waterproof speakers in my garden. Impressed with the sound and bluetooth works flawleasly. My only suggested improvment would be to add l/r channel balance. Currently has trebble base and volume. But again for the price thats being very picky, will only catch you out of your speakers are uneven distences apart. Would buy again if needed

Simplicity itself. Just plug and play. Great sound quality. These are the selling points that I read about before purchase, and by and large, they are very true. But - after a couple of days of fairly constant use in my kitchen, at medium volumes - as it doesn't do 'loud', only 'above normal' - it seemed quieter. I turned it up a bit, and started looking at the volumes of the inputs (Alexa, digital radio). They were fine. After another day, turned up to max was just below the normal level of my old Roberts radio - which actually powers the external speakers pretty well on its own - but doesn't work with the rf interference that this amp - and its charger - gives out. Today, it is back in the packaging, and awaiting being sent back for a refund. Completely disappointing. I shall try one more 'mini' amp from elsewhere, and then just use a small ordinary amp if that comes out as awful...

PROS Compact unit, easy to conceal. Easy to set up. Great sound quality and very loud. CONS Popping when coming on, going off and switching input. Really quite fierce, I apologise to my speakers each time.

I bought this to drive some speakers in the garden , I actually think it would do it , and would use it to drive ceiling speakers in the bathroom. But I was wrong it drives the big speakers in the garden!! And sounds ok 😊👍 great value for the money! To be fair the blue tooth hasn't the range advertised , but that's nothing , it's more than good enough . I would recommend this little amp !
