The available documentation for the Outdoor Portable Metal Speaker MTB-BLSP11 does not include a product-specific recycling statement, recycling symbol, or complete material declaration. Although the product is identified as a metal speaker, the supplied information mainly addresses performance, quality inspection, warranty coverage, and intended outdoor use.
The product record describes the MTB-BLSP11 as an outdoor portable metal speaker with Bluetooth Version 6.0, a frequency response of 120 Hz–20 kHz, distortion below 1%, and a signal-to-noise ratio of 90 dB. It also lists a 7200 mAh battery, a charging period of approximately 4–5 hours, 5–6 hours of operating time, and a wireless transmission distance of at least 10 m. These details explain the speaker’s technical performance, but they do not amount to environmental or material documentation.
The supplied information states that product quality is checked according to GB/T2828.1 and that the product is supported by a one-year warranty. It does not identify the specific metals, plastics, coatings, electronic components, or battery materials used in the speaker. It also provides no instructions for opening, separating, recycling, or disposing of the product and its battery.
Several certification records appear in the broader knowledge base, but they are linked to particular product categories rather than automatically applying to every MIETUBL product. For example, CE and RoHS records are associated with intelligent film-cutting machines and screen protector cutters. LVD and EMC documentation relates to outdoor energy storage power supplies, while RED records cover true wireless stereo headphones and wireless Bluetooth speakers. The supplied MTB-BLSP11 record does not include a product-specific CE, RoHS, or recycling declaration.
The listed application environments, such as gardens, backyards, picnics, tailgating events, camping trips, beaches, poolside settings, street performances, open-air markets, and outdoor workouts, indicate how the speaker is intended to be used. These scenarios do not provide additional evidence about material composition, recyclability, or waste handling requirements.

Not based on the supplied records. The certificates identify their applicable products, including certain cutting machines and screen protector equipment. No product-specific CE or RoHS certificate for the MTB-BLSP11 is included in the available documentation.
The current records support a limited product statement: the MTB-BLSP11 has documented operating specifications, GB/T2828.1 quality inspection, and one-year warranty coverage, but its recycling and material information has not been supplied. Buyers that require environmental or regulatory documentation should request a model-specific material composition, recycling symbols, battery handling instructions, packaging declaration, disassembly guidance, and any applicable environmental certificates before completing a compliance review.
