Marshall makes audio equipment. The company is known for guitar amplifiers, and it also sells headphones, earbuds, and speakers for home and portable listening. The headphone and speaker lines are consumer audio. The amplifiers are musical instruments.
A speaker, a pair of headphones, and an amp are different products with different connections. Bluetooth headphones and earbuds state their battery life and whether they have active noise cancelling on that model’s page. Home speakers and portable speakers differ in size and in whether they need a mains socket. Guitar amps are sold by wattage and by whether they are a head, a combo, or a smaller practice amp.
The product page lists the inputs, the power, and what is in the box. A Bluetooth speaker does not include a guitar amp, and a vintage-style cabinet is not a pair of headphones.
