Review: Perfect ## Features - [ONLY WORKS WITH QUARTET] This single pair of 2.4G wireless headphones is an add-on for the Avantree Quartet bundle (sold separately). Add up to 100 of these headphones to the Quartet bundle and enjoy an outdoor movie or silent concert without disturbing the neighbors. - [LESS DELAYS, BETTER QUALITY] The Quartet-Extra headphones feature 2.4G technology and NOT Bluetooth. This reduces the audio lag down to ~30ms -- significantly less than the 220ms of standard Bluetooth and even the 40ms of aptX Low Latency. This also improves overall sound quality due to 2.4G's higher bit rate & extended bandwidth. - [INDIVIDUAL VOLUME CONTROL] Each pair of wireless headphones are equipped with built-in individual volume controls, so everyone can listen at their own desired volume. - [LIGHTWEIGHT & COMFORTABLE] These headphones are ergonomically designed to be lightweight and flexible, featuring soft memory foam earpads and an adjustable headband.

NOTE: Replaceable earpads are available for purchase. - [EXTENDED PLAYTIME] With a battery life of up to 20 hours, these headphones will last through your longest movie or concert sessions with time to spare. ## Technical Specifications | Specification | Value | |---------------|-------| | ASIN | B09DKS353X | | Age Range Description | Adult | | Antenna Location | Family Movie, Watch TV | | Audio Driver Type | Dynamic Driver | | Audio Latency | 30 Milliseconds | | Battery Average Life | 20 Hours | | Battery Charge Time | 2 Hours | | Box Contents | Ear Cushions | | Brand | Avantree | | Brand Name | Avantree | | Cable Features | Without Cable | | Carrying Case Color | Black | | Carrying Case Material | Faux Leather | | Colour | Black | | Compatible Devices | Quartet Bundle Transmitter | | Control Method | Remote | | Control Type | Volume Control | | Controller Type | wireless volume controller | | Country of Origin | USA | | Customer Reviews | 4.2 out of 5 stars 46 Reviews | | Ear Placement | Over Ear | | Earpiece Shape | Over Ear | | Enclosure Material | Plastic | | Form Factor | Over Ear | | Frequency Range | 20 Hz - 20,000 Hz | | Frequency Response | 20000 Hz | | Headphone Form Factor | Over Ear | | Headphone Jack | 3.5 mm Jack | | Headphones Ear Placement | Over Ear | | Impedance | 32 Ohms | | Impedance Unit of Measure | 32 Ohms | | Is Autographed | No | | Item Weight Unit of Measure | 220 Grams | | Manufacturer | Avantree | | Model Name | WSHT-5049-RX | | Model Number | WSHT-5049-RX | | Network Connectivity Technology | Wireless | | Noise Control | None | | Number of Items | 1 | | Number of Power Levels | 5 | | Product Features | Lightweight | | Specific Uses For Product | Home Theater | | Style Name | Single Headphones | | Subject Character | no character | | Theme | Movie | | Water Resistance Level | Not Water Resistant | | Wireless Technology Type | RF | ## Product Details - **Brand:** Avantree - **Colour:** Black - **Form Factor:** Over Ear - **Impedance:** 32 Ohm - **Frequency Response:** 20000 Hz ## Images ![Avantree Quartet-Extra - 2.4G RF Wireless Add-On Headphones Quartet Multiple Listening System, Scalable to 100 - Image 1](https://m.media-amazon.com/images/I/61CF7f0RcWL.jpg) ![Avantree Quartet-Extra - 2.4G RF Wireless Add-On Headphones Quartet Multiple Listening System, Scalable to 100 - Image 2](https://m.media-amazon.com/images/I/61QZRSp5IuL.jpg) ![Avantree Quartet-Extra - 2.4G RF Wireless Add-On Headphones Quartet Multiple Listening System, Scalable to 100 - Image 3](https://m.media-amazon.com/images/I/51L76wolESL.jpg) ![Avantree Quartet-Extra - 2.4G RF Wireless Add-On Headphones Quartet Multiple Listening System, Scalable to 100 - Image 4](https://m.media-amazon.com/images/I/51zR6jKpkKL.jpg) ![Avantree Quartet-Extra - 2.4G RF Wireless Add-On Headphones Quartet Multiple Listening System, Scalable to 100 - Image 5](https://m.media-amazon.com/images/I/51+ZjmMerZL.jpg) ## Questions & Answers **Q: what cleaning products can i use to clean the headphones?** A: These are the cleaning products we recommend for use on our headphones.

Il tourne en boucle s allumant et s éteignant du coup la batterie toujours vide. ### ⭐⭐⭐⭐⭐ Perfect *by D***T on 1 November 2024* ### ⭐ Nicht zufriedenstellend *by R***S on 19 October 2024* Die Klangfarbe der Kopfhörer ist blechernd und kaum steuerbar. Die zwei Modi Klang- und Aspekteunterstützung der Tonübertragung reichen nicht aus. Für kurzzeitige Präsentationen vielleicht geeignet, aber für längere Tragezeiten unangenehm. ## Frequently Bought Together - Avantree Quartet-Extra - 2.4G RF Wireless Add-On Headphones Quartet Multiple Listening System, Scalable to 100 - Avantree Quartet - 4 Wireless Headphones & 1 Transmitter for Multiple Group Listening Scalable to 100 with No Lip-Sync Delays for TV Watching, Silent Discos, Hearing Assistance in Church, and More - Avantree [Super Stable] Neetto Dual Headphones Stand for Desk, Aluminum Alloy & Metal Gaming Headsets Holder Hanger for Sennheiser, Sony, Audio-Technica, Bose, Beats, Akg, Display Mount - HS908 --- ## Why Shop on Desertcart? - 🛒 **Trusted by 1.3+ Million Shoppers** — Serving international shoppers since 2016 - 🌍 **Shop Globally** — Access 737+ million products across 21 categories - 💰 **No Hidden Fees** — All customs, duties, and taxes included in the price - 🔄 **15-Day Free Returns** — Hassle-free returns (30 days for PRO members) - 🔒 **Secure Payments** — Trusted payment options with buyer protection - ⭐ **TrustPilot Rated 4.5/5** — Based on 8,000+ happy customer reviews **Shop now:** [https://www.desertcart.com.ar/products/567186663-avantree-quartet-extra-2-4g-rf-wireless-add-on-headphones](https://www.desertcart.com.ar/products/567186663-avantree-quartet-extra-2-4g-rf-wireless-add-on-headphones) --- *Product available on Desertcart Argentina* *Store origin: AR* *Last updated: 2026-07-07*
