When it comes to wireless Bluetooth speakers, Sony consistently offers quality products at affordable prices. I've owned quite a few of its SRS speakers and I've always been pleasantly surprised at their durability and sound quality.
Sony's already affordable SRS-XE200 X-Series speaker is now down to $95 on Amazon (save $35), its lowest price on the retailer yet. Sony itself is offering the speaker for $100. On both sites, you can grab it in black, aqua blue or light gray.
This Bluetooth speaker has a carrying strap and only weighs 2.2 pounds, so it can easily tuck away in your backpack or suitcase during expeditions. It's extremely durable too: It has an IP67 rating, meaning it's water-, dust- and shock-proof. The speaker is also equipped with a microphone that has echo-canceling technology, so you're able to take phone calls on it.
The Sony SRS-XE200 is designed to distribute music evenly across a wide sound stage, with X-balanced speakers for powerful bass and crisp sound. Dual passive radiators help this small speaker produce powerful bass notes. On a full charge, you get 16 hours of playtime. Plus, you can customize your sound experience via the Sony Music Center app.
