La recepción bluetooth es excelente. Fuí feliz con él durante tres días, hasta que dejó de sonar y solo quedó emitiendo un click intermitente sin más música. Algo que observé es que se calentaba demasiado, algunas veces era casi imposible tomarlo con las manos por lo caliente que se encontraba. No se si eso habrá sido normal o si era un problema de este aparato en específico. A mi juicio tiene un defecto de diseño en cuanto a su disipación de calor y creo que eso lo dañó finalmente. Considero que vale la pena revisar el diseño, porque su sonido fue excelente mientras funcionó. Review: Small but mighty! - If you've used bluetooth connections from your cell before then you have all you need to know about setting this device up and getting started. Just connect the speaker wires, pair the unit with your phone, turn up the volume on both and enjoy all your favorite music. Once attached, the speaker wire is heavier than the unit itself. So there is a bit of clumsiness in figuring out where to mount or place the unit. We used cable ties. My son and I were amazed at the small size and the volume and clarity that was coming out of the speakers. This product NS-20G 200W is worth the price! I plan on buying one for myself next! Thank you desertcart and Nobsound! ## Features - Mini Elegant Size But Powerful: ① NS-20G mini compact size suits very well for home and desktop use, and the output power is improved to 200W (100W*2) with 2PCS TPA3116 chip; ② You will be amazed by its output power compared to its size when you see it. - HiFi Sound and Bluetooth Lossless Transmission: ① HiFi clear and clarity sound, no audible noise; ② Bluetooth 5.0+EDR+DSP (Digital Signal Processing) to achieve real wireless lossless signal transmission and enjoy much better Hi-Fi sound quality within 15M distance, which brings you high-grade listening feast without any background noise. - NS-20G can be used as headphone amplifier(Only support 15-32Ω headphones).
