Problems, parts and running costs

Summary

The only instrumented test found the sound muddled and very quiet, so it only makes sense if long battery life and a low price matter more than audio quality.

Strengths

  • Battery life is the one thing this speaker does well: an instrumented test measured 60.7 hours.
  • Two speakers can be paired for stereo over TWS.
  • The RGB lights can be switched off to stretch the battery.
  • A hands-free mic and an AUX input are built in.
  • It is small and cheap enough to treat as disposable.

Weaknesses

  • The only instrumented test scored it 47 out of 100 and called it a waste of money.
  • Sound is muddled and boxed in, and volume measured just 83 dB, about phone-speaker loudness.
  • It fell apart after a single three-foot drop, and the plastic bumpers break off easily.
  • IPX5 is splash-resistant, not waterproof, and the charging port must stay closed near water.
  • Units in owner comments stopped working after a few days or would not reset.
  • There is no app, no EQ and no multipoint pairing.

Sound and volume

TechGearLab bought and measured this exact speaker and gave it 47 out of 100, last of the 15 budget speakers it tested. It described the sound as muddled and boxed in, with muddy bass at high volume and muffled mids and treble. Volume measured 83.3 dB, one of the quietest in the test and about the loudness of a phone speaker, with distortion at maximum. The same test gave battery a 9.0 out of 10 and measured 60.7 hours, and it called the speaker a “waste of money” at its $60 list price. No RTINGS, Wirecutter, Tom’s Guide, CNET or PCMag test of this exact model was found.

Battery life and charging

The advertised 24 hours is conditional: BolaButty’s guide quotes it at 30% volume with the lights off, while a manual sheet says 20 hours at 50% volume. The only instrumented run measured 60.7 hours, far above both claims, so treat the headline as a best-case figure rather than a typical one. Charging is over USB-C at 5 V / 1 A, and the manuals disagree on how long it takes: about five hours in one, about one hour in another. The battery is not user-replaceable, so a recharge always means taking the speaker out of use.

Build, water resistance and reliability

The body is hard plastic with rubber bumpers, about two soda cans long, with a lanyard point. Durability tested poorly: TechGearLab reported the unit broke after a single three-foot drop, with the hard plastic bumpers coming off easily. Owner comments on the manual pages describe units that stopped working after a few days and units that would not reset. Nobody has published a failure rate, so treat these as caution signals rather than a measured defect rate. The buttons also need a hard press to register.

Is it worth it?

The case is price-driven. Below roughly $20 the long battery and the low cost can justify it as a casual speaker for podcasts or a party of one. Around $20 to $25 the case weakens, because better-tested budget speakers compete at the same money. At BolaButty’s own $34.99 store price (October 2026), and especially at the $60 list price TechGearLab cites, the weak audio, low volume and fragile build make it hard to recommend. There is no subscription and no app, so the only recurring extra is an AUX cable, which is not included. The warranty is 12 months; “lifetime technical support” is technical help, not warranty cover. If sound quality or durability matters even a little, spend the small amount more on a tested alternative.

Which model this is

This page covers the BolaButty X-GO C27-C (C27C); the black US Amazon listing is ASIN B0BRKPVZB4. BolaButty sells the same model in many colorways. The Amazon brand field reads “Bluetooth”, which is generic, not the manufacturer; the real maker is BolaButty. Spec listings drift between revisions, so match on the C27-C model name before buying.
