Reviews last updated: August 2026 · How we calculate this

What customers like about Cambridge Audio G2

  • Sleek and elegant premium aluminum design
  • Compact and highly portable size
  • Powerful and rich audio output for its physical footprint
  • Acts as a power bank to charge mobile devices via USB
  • Built-in microphone for speakerphone functionality
  • Supports NFC for quick and effortless Bluetooth pairing
  • Ability to wirelessly link two G2 speakers together for extra power
  • Can connect to two Bluetooth source devices simultaneously

What customers don't like about Cambridge Audio G2

  • Audio can sound muddy or too heavy in the low-mid frequencies
  • Vocals and spoken word audio (like podcasts) can feel slightly muffled
  • Real-world battery life often falls short of the advertised 10 hours, lasting around 6 hours at normal volume
  • Requires a bulky proprietary AC power adapter instead of standard micro-USB or USB-C charging
  • Lacks on-device track skipping controls
  • Not ruggedized or water-resistant, making the metal casing prone to scratches
  • Some long-term users report the internal battery completely failing to hold a charge after several months of use

Verdict

The Cambridge Audio G2 is an ultra-compact portable Bluetooth 4.0 speaker measuring 189 x 67 x 55mm and weighing 649g, featuring a premium aluminum body housing a four-driver configuration that includes two 50mm full-range drivers and two 50mm passive bass radiators driven by a Class-D digital amplifier. Its standout features include a 10-hour rechargeable lithium-ion battery that pulls double duty as a power bank via its 1A USB charging port, quick NFC touch pairing, multi-speaker synchronization using an A/B mode switch, and an integrated speakerphone microphone. On the downside, the speaker lacks native track playback navigation buttons on its physical interface, lacks support for the high-fidelity aptX codec, possesses no water-resistant ruggedization for outdoor environments, and can occasionally exhibit slightly muffled vocal clarity due to its heavily low-mid emphasized sound profile.
