The available product documentation for the Outdoor Portable Metal Speaker MTB-BLSP11 does not include a product-specific recycling declaration or material disclosure. Although the speaker is described as a metal model and its electrical performance is documented, the supplied information does not identify its complete material composition, recycling symbols, packaging materials, or end-of-life handling requirements.
The records currently support several operational and quality-related details. The MTB-BLSP11 uses Bluetooth Version 6.0, offers a frequency response of 120 Hz–20 kHz, maintains distortion below 1%, and includes a 7200 mAh battery. Its stated charging time is 4–5 hours, operating time is 5–6 hours, signal-to-noise ratio is 90 dB, and wireless transmission distance is at least 10 m.
These specifications explain how the outdoor speaker performs, but they should not be interpreted as environmental or material compliance documentation. The product record also refers to GB/T2828.1 quality inspection and provides a one-year warranty. Neither item confirms recyclability, material percentages, battery disposal procedures, or packaging declarations.
The MTB-BLSP11 is positioned for outdoor activities such as camping, hiking, picnics, tailgating, beach and poolside use, garden gatherings, open-air markets, street performances, and outdoor exercise. These applications describe the intended usage environment only. They do not establish environmental labeling, a recycling pathway, or a declaration of the speaker’s material makeup.
Similarly, references in the broader knowledge base to CE, RoHS, LVD, EMC, and RED certificates relate to specified product categories. Examples include intelligent film-cutting machines, screen protector cutters, outdoor energy storage power supplies, true wireless stereo headphones, and wireless Bluetooth speakers. The supplied MTB-BLSP11 documentation does not assign any of those certificates specifically to this model, nor does it provide a recycling declaration for it.

No. It identifies one aspect of the product description, but it does not disclose the full composition of the housing, internal parts, coatings, battery, or packaging. A complete declaration would require more detailed material information.
Not based on the supplied data. The available certificate references identify other products or categories, while the MTB-BLSP11 record does not contain a model-specific CE or RoHS certificate.
Based on the available records, the MTB-BLSP11 has documented performance specifications, GB/T2828.1 quality inspection, and one-year warranty coverage. However, no product-specific recycling declaration or full material disclosure is available. Buyers or compliance teams that need environmental documentation should request the material composition, recycling and disposal marks, battery handling requirements, packaging details, and any certificates that explicitly name the MTB-BLSP11 before reaching a compliance conclusion.
