Review: So glad I bought them! - After reading mixed reviews, and putting much thought and deliberation into it, I purchased the set for my pool area. I'm so glad I did. These are an outstanding alternative to hard wired speakers! The sound quality is remarkably good, with nice bass and treble response. The enclosures are a little larger which attributes to nice bass tones. The dock station comes with an a/c power adapter or you can use it completely wireless by using using 4 AA batteries in the unit. I have used this with my iPhone and it works great. We use the SiriusXM application, Pandora, and the iPod functions and the unit has performed great. I have noticed there is a little interference when using an iPhone when you send or receive text messages while the unit is playing, so this may be the crackling/noise interference some owners are experiencing when using the speakers. This unit also comes with RCA connections so you may plug the dock station into your home theater system/stereo system, PC, cable TV, or satellite dish receiver to use as well. You simply plug the RCA connections into your audio out (red/white plugs) on your home system, cable box, or satellite receiver and use the wireless transmitter's plug to connect to the RCA plug. Of course, to use with a PC, you will not need to use the RCA cord provided, just simply plug the dock station into your PC's headphone jack. We tune into the music channels via DirecTV and the unit had ZERO interference while using this setup. The speakers produce an amazing stereo effect. We have had several guests over to our home and they are literally blown away with these speakers partially hidden in our landscape. Now for the cons: It's really not a con....It's an issues others have mentioned, but I have found a fix to it. Like others have said, there is no volume control on the wireless dock station and the volume has to be adjusted on each speaker. There's an easy solution. If you use an iPhone, iPod, any MP3 device, home stereo/home theater, PC, cable/satellite box, the volume can be adjusted with the device you connect to the dock station. The key is to turn the volume down on the device you are connecting with (let's say at to the least half way mark to start out), and turn the volume up on your wireless speakers outside. Use the volume on your connected device (Ie: iPod, etc) to turn the volume up and down on the speakers outside. It's that easy! When I connected the dock station with my satellite receiver, I could use the receiver's remote to adjust the volume outside. Problem solved! Pros: After 16 hours of operation, I couldn't be more pleased. Upon receiving these, I charged the speakers for about five hours. I used the speakers for about four hours with no problems. I decided to charge them overnight to use them the next day, and used them for over twelve hours on a 97Β° day at a fairly high volume level with no issues. The product looks great, and blends in with my landscaping. It's a fairly large (tall) unit, but it looks great. I highly recommend this product. It's so easy to use, looks, and sounds great! Review: Great find. Highly recommend. - Really, really like these speakers. Since we weren't taking a real summer vacation this year and stayed home by the pool most weekends, they were an awesome addition to our attempt to make it feel more like a resort! The quality of the sound is great; the speakers blended in nicely with our landscape and they seem to handle mild water splashes very well. They are sturdy, but not too heavy to easily carry from place to place. They are very versatile and played a multitude of items, from our android phone, to our iphones, to our computer (where all my itunes library is best contained), to--best yet--the TV. We like to watch TV from the jacuzzi but sometimes can't hear it as well when the bubbles are on, so these speakers right next to us, plugged into the TV audio out, solved that problem. All the connectors we needed came with the speakers too. The signal is rarely a problem as all of the items are within lkess than 75' of each other. Sometimes there's a bit of interference, but then we slighly move the speakers and problem solved. The speakers hold a charge quite well and almost always last the whole day--I think. They might even last longer, except at the end of the day of full use, we usually take them to the house to charge them overnight. Only two negatives. The base is not very good on battery. I think the signal is too weak to perform well, when there's not a/c power, so we normally keep the base/player at an outlet and have no problems. One other negative is that the touchpad for the on/off button is a little wimpy..seems like it's going to need to be reglued at some point soon. But all in all, especially for the price, this was a great find. I highly recommend these. ## Features - Operating Distance: Up to 150 feet. Speaker Design: 2-way - Frequency: 900MHz.

I post this because of my extreme dissatisfaction with this product. They are going back tomorrow. This purchase was for the 3rd set of wireless speakers in 12 years. The first set was new technology for the times and needed to be tuned to get relatively ( I use the term loosely) decent sound. I suffered through them for almost 2 years before I sought a replacement. I replaced them with an RCA system. They were great! No tuning, all you needed to do is turn them on and you got music. I could place them anywhere around my house (front or back yard), never an issue with sound quality. The sound quality was very good for this relatively new technology. The transmitter stopped working after about 10 years, so I thought it was time to update to new technology or so I thought. I read the reviews and that is why I bought these. These speakers need to be 'tuned', the sound quality is very poor, the sound goes in and out constantly. They claim a distance of 150 feet from the transmitter. We are lucky to get 10. For you doubters, they have been charged for 20+ hours. I would not recommend these speakers to anyone. I could write more, but I didn't want to be too verbose. --- ## Why Shop on Desertcart? - πŸ›’ **Trusted by 1.3+ Million Shoppers** β€” Serving international shoppers since 2016 - 🌍 **Shop Globally** β€” Access 737+ million products across 21 categories - πŸ’° **No Hidden Fees** β€” All customs, duties, and taxes included in the price - πŸ”„ **15-Day Free Returns** β€” Hassle-free returns (30 days for PRO members) - πŸ”’ **Secure Payments** β€” Trusted payment options with buyer protection - ⭐ **TrustPilot Rated 4.5/5** β€” Based on 8,000+ happy customer reviews **Shop now:** [https://www.desertcart.jp/products/3334711-c2g-cables-to-go-audio-unlimited-900mhz-wireless-indoor-outdoor](https://www.desertcart.jp/products/3334711-c2g-cables-to-go-audio-unlimited-900mhz-wireless-indoor-outdoor) --- *Product available on Desertcart Japan* *Store origin: JP* *Last updated: 2026-11-08*
