The Anker Soundcore 2 is the best budget pick under $100, delivering clean bass, around 24 hours of battery and IPX7 water resistance for a price that's often well under $50. Its spiral bass port keeps the low end tidy where rivals get muddy, making it a remarkable value. The sound can strain at high volume and it still uses micro-USB, but as an affordable, long-lasting everyday speaker it's hard to argue with.

Strengths
  • — Clean, surprisingly capable bass from a unique spiral bass port
  • — Outstanding battery life rated around 24 hours
  • — Excellent value, frequently available for well under $50
Watch-outs
  • — Overall sound quality trails pricier rivals and can sound strained when loud
  • — Bass lovers will still want more low-end punch
  • — Older micro-USB charging rather than USB-C

Sony SRS-XB100
3 sources$39.01as of Sep 25

The Sony SRS-XB100 is the best truly tiny Bluetooth speaker under $100, packing surprisingly full, bass-forward sound and a built-in mic into a body the size of a soda can. Its IP67 rating, roughly 16-hour battery and 274g weight make it a brilliant shower, hiking and travel speaker. It can't fill a big space and its app is bare-bones, but for portable, balanced sound on a budget it's a standout value.

Strengths
  • — Impressively full, balanced sound and bass for such a tiny speaker
  • — Excellent portability at just 274g, fits in a cup holder or jacket pocket
  • — IP67 waterproof and dustproof for shower and poolside use
Watch-outs
  • — Not powerful enough to fill a medium room or backyard
  • — Treble is slightly dampened by the speaker's upward-firing position
  • — Sparse features in the Sony Music Center app

How they stack up

Anker Soundcore 2

It trades the IP67 toughness of the JBL and Sony picks for slightly lower IPX7 water resistance and lacks their USB-C charging, but its spiral bass port keeps the low end cleaner than its price suggests.

Sony SRS-XB100

Unlike the JBL Clip 5 it has no carabiner but adds a built-in microphone for calls, and like the Clip 5 and Anker Soundcore 2 it's a personal-listening speaker that can't match the Flip 6 or Wonderboom 4 for room-filling volume.
