Third-party reviews

What customers like about Nakamichi NBS 9

  • Premium lightweight and compact design with an aesthetic inspired by traditional phones.
  • Equipped with Near Field Communication (NFC) technology for quick and easy Bluetooth pairing.
  • Versatile connectivity options including Bluetooth, a 3.5mm AUX input, and a TF card slot.
  • Decent, well-balanced sound quality with clear acoustic vocals for its price tier.
  • Features a built-in microphone for hands-free speakerphone calls.

What customers don't like about Nakamichi NBS 9

  • The prominent physical on/off switch easily snags on objects inside bags, causing the speaker to accidentally power on and drain its battery.
  • Dual-purpose volume buttons (which also control track playback) make it difficult to make precise, subtle volume adjustments.
  • Audio quality can sound slightly tinny or hollow, especially at higher volumes.
  • Lacks deep bass response, with low frequencies receding noticeably at maximum volume.
  • Relatively short battery life of up to 5 hours compared to newer portable speakers.
  • Lacks a battery level indicator to easily monitor remaining charge.

Verdict

The Nakamichi NBS 9 is a hump-backed bridge-shaped portable Bluetooth 3.0 speaker measuring 205 x 60 x 50mm, weighing 172g, and offering a total body volume of 615 cm³. Designed for both indoor and outdoor use with a 10-meter wireless range, it features water resistance, an integrated microphone for hands-free calls, NFC pairing, physical cross-shaped control buttons, and a 3.5mm auxiliary input for wired connections. Its built-in rechargeable Lithium-ion Polymer battery yields up to 5 hours of continuous audio playback. The main advantages of the device include its excellent portability, seamless NFC smartphone pairing, and strong volume output capable of filling a room despite its small footprint. On the downside, it requires a sluggish micro-USB charging port rather than a modern connection, utilizes an older Bluetooth version, and its awkward, non-pocketable shape forces users to carry it inside a bag.
