RIVA S RTS01G Premium Bluetooth Speaker

As a hifi enthusiast wanting something portable for the home office/kitchen/bathroom this looked perfect from the specification and online reviews. First sound quality impressions were good but maybe not quite as stellar as many of the reviews were suggesting, with the out of box sound a little more 'muffled' than I wanted. However give it time and use - with a hundred plus hours the sound quality has improved in every area and is to my critical ears excellent for the money and the type of device. It really shows up the variable quality of the source material but MP3s played from Amazon Prime via my Sony Xperia Android Phone using Bluetooth aptX generally sound good. With my typical 50% volume usage the battery lasts at least 10 hours, but I have found it does sound a bit better with a slightly greater bass presence when plugged into the mains, particularly as the battery runs down. Build quality and operation is great too. Zero Bluetooth drop-outs so far. Even my daughter likes listening to her music on it which is definitely a first!

Sounds good, it looks good, but battery weak.

I'm a massage therapist and I've used this to play music for sessions over a few months, so I've had a chance to observe many people's reactions to the sound. The keyword tends to be "wow". It's just amazing to have something this size that I can carry around with me, and not compromise so much on sound quality. It's not quite as wonderful as my home 5.1 surround system but it's surprisingly close. The sound quality is adequate to not distract from the music, it really helps to create a tranquil space. Nice looks and easy bluetooth compatibility a bonus (I've often connected it to other people's phones/laptops too). The only thing I would change about it is that it makes a loud beeping sound when I have incoming calls on my phone, even when I've set the incoming calls to silent.If you are looking to buy speakers, I highly recommend Oluv's interactive comparison tool - [...]that's how I could hear/compare lots of different speakers, and this one was my favourite.

This little speaker is a doddle to use, and produces a full, rich sound, quite remarkable for such a small speaker. It seems very well built, and has a high quality feel to it. I'm not convinced that the battery life is quite what it is claimed to be, but it's not really an issue for me, as I don't intend to use it on the move, i.e. remote from a power supply. The price from Amazon was great too - £80 for a speaker with a RRP of £200. Overall, very pleased.

This tiny unit is beautifully built and supplied with an excellent carrying case and a decent solid charger. The sound is simply remarkable - definitely one of the best bluetooth speakers available. Give it a few hours for the drive units to wear in before judging it (the manufacturers say three hours, but I reckon more like twenty). This unit has superb clarity and presence. Maybe not the loudest out there, but the quality really is stunning. If you like acoustic and classical music this is one speaker that will not let you down, although the bass performance on more contemporary tunes is remarkable too. People hear the sound and can't believe it's coming from this little box!

The outer box was unsealed. The protective sleave or transport cover was marked and dirty. I suspect this was either ex-display or refurbished. Can't decide if the speakers are damaged or not but the sound is not very bright - seems to lack treble tones. Gave 2 stars originally.Update: sound has improved with use - maybe the speakers need to warm up a bit? However all the other issues still stand. Have increased review by 1 star

A very good speaker for its size, only let down by lack of common microUSB charging, lack of full water proofing (its just splash proof) and lack of playback buttons (play, pause, previous and next)

Excellent sound from such a small and totally portable device. It isn't Hi-Fi quality but no-one would expect that from a Bluetooth speaker.The speaker gets better with time so allow a bit of "breaking-in" for the best sound.
