The model is CM390, and the adapter supports A2DP, H2DP, HSP, AVRCP and HID protocols. Its stated transmission distance is 20 metres in a barrier-free environment. The packaging measures 114mm x 102mm x 8mm, and the pack contains one Bluetooth adapter.

It does not list housing material, chipset, power rating or operating system compatibility, so the practical focus stays on the stated connection type, protocols and transmission distance.\u003c\/p\u003e\n\u003ch3\u003eMaterial and Build\u003c\/h3\u003e\n\u003cp\u003eThe exact housing material is not stated in the source text. What is known is that the product is a USB Bluetooth adapter with model number CM390. The package size is 114mm x 102mm x 8mm, which describes the supplied packaging rather than the adapter body. Because material and build details are not provided, no claims are made about durability, finish or internal components. Buyers should rely on the confirmed model, Bluetooth version and protocol list when checking suitability.\u003c\/p\u003e\n\u003ch3\u003eSize and Practical Fit\u003c\/h3\u003e\n\u003cp\u003eThe only dimensions given are 114mm x 102mm x 8mm for the package. The adapter itself is described as a USB Bluetooth adapter, so it connects through a USB port on a compatible host device. The transmission distance is 20 metres in a barrier-free environment, which is a line-of-sight figure. Walls, furniture, wireless interference and the host device can all reduce real-world range. No adapter body dimensions are supplied, so no separate size claim can be made.\u003c\/p\u003e\n\u003ch2\u003eUses and Placement\u003c\/h2\u003e\u003cdiv style=\"text-align: center;\"\u003e\u003cimg alt=\"USB Bluetooth adapter 5.0 model CM390 with 20 metre barrier-free range and protocol support\" src=\"https:\/\/images.seoo.uk\/src\/products\/shopify_export\/US14\/3247\/2025-10-16\/original-image\/6be2a1c9-e261-4da6-a83b-bb31659aa793.webp\"\u003e\u003c\/div\u003e\n\u003cp\u003eThis adapter is relevant where a USB host needs Bluetooth 5.0 connectivity for supported audio or human interface device tasks. The listed protocols cover common wireless audio and control functions, but the source does not specify which operating systems or exact devices are supported. Placement should keep the adapter within the stated 20 metre barrier-free range for the best chance of a stable connection.\u003c\/p\u003e\n\u003ch3\u003eEvent or Professional Use\u003c\/h3\u003e\n\u003cp\u003eFor event or professional setups, the adapter can be used where a compatible USB host needs Bluetooth audio or device connectivity. The support for A2DP, H2DP, HSP, AVRCP and HID protocols means it is intended for common streaming and control profiles. The 20 metre barrier-free figure may suit open rooms or temporary installations, but the source does not confirm multi-device pairing, codec support or latency performance. Check the host system requirements before relying on it in a live environment.\u003c\/p\u003e\n\u003ch3\u003eEveryday Home Use\u003c\/h3\u003e\n\u003cp\u003eAt home, the adapter may be used to add Bluetooth functionality to a compatible USB device. The single-adapter pack keeps the setup simple, and the Bluetooth 5.0 version is clearly stated. The 20 metre barrier-free distance gives an idea of open-space range, but normal home walls and other wireless signals can shorten it. No colour options, LED indicators or button functions are listed in the source text, so those details cannot be confirmed.\u003c\/p\u003e\n\u003ch2\u003eBenefits and Buying Value\u003c\/h2\u003e\u003cdiv style=\"text-align: center;\"\u003e\u003cimg alt=\"USB Bluetooth adapter 5.0 model CM390 with 20 metre barrier-free range and protocol support\" src=\"https:\/\/images.seoo.uk\/src\/products\/shopify_export\/US14\/3247\/2025-10-16\/original-image\/768592cc-3504-4166-8751-300970689443.webp\"\u003e\u003c\/div\u003e\n\u003cp\u003eThe main buying value comes from the confirmed Bluetooth 5.0 version, model CM390, compact adapter format and broad protocol list. The stated 20 metre barrier-free range is useful for comparing placement needs, and the package dimensions give a clear idea of the box size. Because price, warranty and compatibility lists are not supplied, value should be judged on the stated specifications.\u003c\/p\u003e\n\u003ch3\u003eReuse and Low Maintenance\u003c\/h3\u003e\n\u003cp\u003eThe source text does not provide care instructions, so only basic low-risk guidance is possible. Keep the adapter dry and avoid unnecessary force when inserting or removing it from a USB port. The single-adapter pack means there are no extra units to store or maintain. No information is given about firmware updates, driver software or replacement parts, so those points should be confirmed separately if they matter to the buyer.\u003c\/p\u003e\n\u003ch3\u003eWhy Choose This Product\u003c\/h3\u003e\n\u003cp\u003eChoose this adapter when the confirmed details match the requirement: Bluetooth 5.0, model CM390, USB connection, support for A2DP, H2DP, HSP, AVRCP and HID protocols, and a stated 20 metre barrier-free transmission distance. The package dimensions are 114mm x 102mm x 8mm and the pack contains one Bluetooth adapter. If the host device needs a specific operating system, codec or certification, those details are not stated here and should be checked before purchase.\u003c\/p\u003e\u003cdiv style=\"text-align: center;\"\u003e\u003cimg alt=\"USB Bluetooth adapter 5.0 model CM390 with 20 metre barrier-free range and protocol support\" src=\"https:\/\/images.seoo.uk\/src\/products\/shopify_export\/US14\/3247\/2025-10-16\/original-image\/86e1b404-e097-4c9b-867f-9a46a77c8761.webp\"\u003e\u003c\/div\u003e\u003cdiv style=\"text-align: center;\"\u003e\u003cimg alt=\"USB Bluetooth adapter 5.0 model CM390 with 20 metre barrier-free range and protocol support\" src=\"https:\/\/images.seoo.uk\/src\/products\/shopify_export\/US14\/3247\/2025-10-16\/original-image\/d858c906-277d-49c7-b71b-73fceefdf5f2.webp\"\u003e\u003c\/div\u003e\u003cdiv style=\"text-align: center;\"\u003e\u003cimg alt=\"USB Bluetooth adapter 5.0 model CM390 with 20 metre barrier-free range and protocol support\" src=\"https:\/\/images.seoo.uk\/src\/products\/shopify_export\/US14\/3247\/2025-10-16\/original-image\/e3e85ca1-536e-45ea-b214-c9bf887aa55e.webp\"\u003e\u003c\/div\u003e","brand":"qpnzh3-kj","offers":[{"title":"Bluetooth adapter","offer_id":58698301538648,"sku":"CJUS167432001AZ","price":19.98,"currency_code":"GBP","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/1001\/4110\/5496\/files\/86e1b404-e097-4c9b-867f-9a46a77c8761.webp?v=1791465274","url":"https:\/\/neocrest.velnovique.com\/products\/usb-bluetooth-adapter-5-0-transmitter-model-cm390-with-20-metre-range-and-a2dp-h2dp-hsp-avrcp-hid-protocol-support-for-audio-and-device-connectivity","provider":"NeoCrest.uk","version":"1.0","type":"link"}
