UDISON Wireless Bluetooth 5.0 Speakers, Outdoor Portable Stereo Speaker with 10W Rich Bass,164-328 ft,12-Hour Playtime,Built-in Mic Handsfree, USB Port &TF Card Slot

Tested with Moto X4. Solid connection at 40 feet with 2 walls between. Farther without walls but I could not get 164 feet. Good sound and volume. Nice buttons on top but I wish they were marked better for visibility. Volume control is a problem since you need to long press the multi-function buttons. This makes it hard to make small changes to get the sound just right. It would be better if it was a short press for volume changes and a long press to change tracks. Power button on back is nice but I sometimes forget to turn the speaker off. It would be better if the speaker automatically powered down after 10 minutes of non-use. Overall though a very good value.Revised 8/21/18This seller seems to be really concerned about customer satisfaction. I made a couple of suggestions on ways to improve their product and they did not try to make excuses but forwarded those suggestions to their engineers for improvement. I will not hesitate to buy from them again in the future and look forward to their next generation of speakers. For this reason I raised rating from 3 to 4 stars.

I needed a bluetooth speaker to replace one that I had lost, but wanted one that had the newest bluetooth technology in it. Bluetooth 5.0 has been out for a while, but not many devices were equipped to utilize it at first. Bluetooth 5 will likely become the de-facto version of Bluetooth over the next few years.The speaker has a decent weight to it for the size. This weight is directly proportional to the amount of power and sound the speaker can put out. The sound from the speakers is crisp and clear, even at full power! Doesn't really distort based on the genres of music I put it through (hip hop and progressive house). It also has 3.5mm connections for when you'd want to use a wire (buy why?).The speaker gets but does not have a lot of bass punch in it, but maybe it's because of the size of the speaker, as I'm used to very large bookshelf speakers. Either way, I needed a bluetooth speaker replacement and I haven't been able to deplete the battery yet from the first full charge.

I was really surprised at the Great Quality and impressive sound this Bluetooth speaker exhibits. The speaker has a nice weight and is very solid, it just feels like a well constructed product. The speaker has a very balanced and rich sound that comes from this surprisingly small package. The setup is very straight forward and it is easy to connect it to the Bluetooth sound source of your choice. My setup was accomplished in under 40 seconds after I had charged the unit for about 30 minuets by simply following the clear voice prompts which made the connection a fast and simple task. The sound is not that of a high dollar sound system which might be an unrealistic expectation for this item. The sound is very nice for such a compact unit. The highs are clear, the mid range is not muddled like other units but as the high range it is very clear and clean. The low end is surprisingly very solid and clean and clear for such a small enclosure. The stereo separation is easily discernible and surprising because of the relatively short distance between the drivers I like this Bluetooth stereo very much, you might like it too!

I was surprised and had some disbelief that a speaker at this price point would have a long range.I just got this to carry sound from my church's sanctuary to the nursery at the opposite end of the building. I am pairing it with a Renkforce BTHP-100 Bluetooth® audio transmitter/receiver that I bought while I was in Germany.I feel pretty good about my test results. I positioned the transmitter next to my south facing exterior wall and walked the speaker out my north facing front door (closed the door, and across my cul-de-sac before the sound started dropping out. I will see how it performs this Sunday. If the performance in church is significantly better or worse than I would expect, I will update to give details.A point for everyone to take note, if you want to have a speaker xxx feet from your Bluetooth transmitter, then you have to purchase a transmitter with that range and a speaker with that range. the signal drop will depend on the lowest range component.

This little speaker is quite a punch for its size and cost. The battery last for awhile (12-13 hrs) but I don’t like how it doesn’t give me a warning of low battery, it just shuts off :(. The Sound quality is great for desk volume or a quiet beach, but not great for dinner parties or anything it has to compete with. The sound isn’t boisterous enough to have clarity with higher volume. I use this at my desk at work and it’s my favorite. It’s easy to connect to and the sound is crisp at lower to moderate volumes. I’m happy with my purchase

Works well as bluetooth with phone.But, what I really wanted was the TF card feature. Keeps the phone from discharging and lower data rates.The sound is very poor in the TF card mode, it hesitates or warbles. No, it's not the TF card, we've tried others that work well.When the unit is charging, the indicator lamp never stops flashing to show it's finally charged.A previous experience with a Udison was very good, so this upgraded model was purchased.www.amazon.com/gp/product/B075WZ16CX/ref=ppx_yo_dt_b_search_asin_title?ie=UTF8&psc=1We'll go back to this product, it's been making us happy for a while. Need more than a couple around, these are so economical I can just have them by the pool, in the garage or the back of a truck.The use of this previous unit out on the lake last night made think, perhaps I should create a review of the newer model
