Brand: Teufel

Manufacturer: Teufel

The Teufel Rockster Go 2 is a portable speaker designed for outdoor and on-the-go use, offering a solid combination of durability and wireless convenience. Weighing 735 g and measuring 210 × 110 × 60 mm, it strikes a balance between portability and physical presence. Full waterproof protection backed by an IP67 rating means it can handle submersion without issue, making it a practical option for varied environments. A control panel placed directly on the device keeps operation straightforward, and voice prompts provide audible feedback during use.

Internally, the Rockster Go 2 runs two 50 mm drivers covering a frequency range of 60 Hz to 20,000 Hz, with a passive radiator supporting the low end in place of a dedicated subwoofer. Stereo playback is supported, and two units can be paired together for expanded stereo sound. Connectivity relies on Bluetooth with AAC codec support and a maximum range of 10 m, alongside a USB Type-C port for charging. Battery life is rated at 28 hours, with an onboard indicator to track remaining charge. Fast pairing and smartphone remote support are also included, along with a sleep timer for scheduled playback cutoff.

Pros

IP67 rating provides full waterproof and dust-proof protection, making it suitable for outdoor and wet environments
Battery life of 28 hours allows for extended use between charges
Stereo playback is supported, with the option to pair two units for wider stereo sound coverage
A passive radiator supplements the low-frequency output without requiring a dedicated subwoofer
Fast pairing simplifies the process of connecting a Bluetooth device quickly
A sleep timer allows playback to stop automatically after a set period

Cons

Bluetooth range is limited to 10 m, restricting the distance between the speaker and the source device
No AUX input or 3.5 mm audio jack means wired audio playback is not possible
Wireless charging is not supported, requiring a wired connection for every charging session
No advanced Bluetooth codecs beyond AAC are available, limiting audio transmission quality options
The speaker cannot function as a power bank, so it cannot charge other devices on the go
No mute function is available for quick audio silencing

Who is this for?

This speaker is well-suited to users who need a durable companion for outdoor activities, given its IP67 waterproof rating that handles exposure to water and dust without issue. The 28-hour battery life makes it a practical choice for extended trips, camping, or all-day outdoor use where recharging is not always convenient. Users who want to expand their listening setup can also benefit from the stereo pairing feature, which links two units together for broader sound coverage across a room or open space.

Who is this NOT for?

Users who rely on wired audio connections will find this speaker limiting, as it lacks both a 3.5 mm audio jack and an AUX input, leaving Bluetooth as the only playback method. Those who prioritize high-fidelity wireless audio transmission may be underwhelmed by the absence of advanced codecs such as aptX, LDAC, or aptX HD, with AAC being the only supported option beyond standard Bluetooth. Additionally, users who need their speaker to double as a power bank for charging other devices on the go will need to look elsewhere, as that functionality is not present.
