Sometimes has an issue locking onto pin. Verify with gps.

Amazing sound quality! You will not he disappointed with this speaker....very loud, very clear sound.

Great quality speaker for the price. Love the design and the clarity of the sound.

The Sony SRS-XG300 pumps out a lot of sound for a battery powered speaker that's a little over a foot long and about six inches in diameter. Yes, it's enough to fill a room. I haven't maxxed out the volume, but I've pushed it up high enough to make normal conversation difficult. The music stayed distortion free without breakup. You won't have any trouble hearing it on a beach (just don't annoy those nearby). I found the sound to be full and relatively well balanced with a slight emphasis towards the middle and high frequencies. I'm sure you can adjust the equalization if you download the app. I've yet to do so because I'm using this with an audiophile DSD MP3 player. One reviewer noted the lack of a tweeter. You would never know it blindfolded. I can't really tell what's underneath the hood. Whether or not it has one is irrelevant to me. Technology evolves. Trust your ears. I'm hearing percussions that I never knew existed in some of my music.This isn't a lightweight speaker. It's as solid as a rock and looks like it can withstand rough handling. Just exercise due care with the cones. I've already gotten several hours of use at moderate volume levels with my initial charge. Sony claims you can get up to 25 hours when the battery is new, with a gradual decrease after repeated charges. You're volume level will naturally determine how much use you'll get between charges as well. Controls are straightforward. At the left, you have on/off, bluetooth on/off, and mega bass. Pressing the mega bass doesn’t significantly increase bass. It just adds a bit more depth. At the right, you have play/pause, volume up, and volume down. At the rear, you have a soft rubber flip down flap with a USB-A port, a USB-C port, an input for an external source, a push button with a voice that tells you battery status, and an on/off push button to activate/deactivate the woofer lights. The USB-A port is a convenient feature which allows this speaker to double as a power bank. Handy for a drained phone! A wall adapter for charging is included and it’s a plug-in electrical adapter, not a USB. My bluetooth device recognized and connected with the speaker flawlessly without even resorting to the instructions.I’m very well pleased with the quality of the audio and portability of this unit. It’s going to be a staple for future road trips. There’s one thing I’ve yet to determine and that’s if the app is only active when playing music through my phone or if I can control the app while playing music through my MP3 player. I hope to report my findings in an update to this review.

I was impressed with the clarity and sound. Good buy.

Sound quality exceeded expecations. Crisp, clear and it can get quite loud. Bass okay, but helps to be on large table or next to wall to reinforce.

I LOVE THESE !!!!!!!... GREAT QUALITY! LONG LASTING BATTERY LIFE AND VERY COMFORTABLE ON THE EAR. VERY SATISFIED!1

It sounds like the person’s voice is inside your head and when I speak they hear me much better than on speaker. I’m slightly hard of hearing and these help a lot.
