## Description

From the manufacturer T20 Wireless HiFi in-ear monitor with detachable cable, wireless neckband and audio tuning filters. High-Resolution Audio Founded in Glasgow, RHA draws inspiration from the UK's rich heritage of invention and engineering. Every component is engineered by our team to achieve the highest quality performance, using advanced techniques and premium materials. RHA DualCoil™ Drivers RHA’s proprietary DualCoil driver is an upgraded version of a standard dynamic driver, adding an extra voice coil and custom diaphragm. This setup gives equal focus to bass, mids and treble frequencies, allowing for audio without distortion. The DualCoil produces music with both power and depth - and crystal-clear detail - simultaneously. It's all in the details... Tune your Audio Changeable tuning filters enable you to modify the sound signature of your audio. Use bass filters to add power to hip-hop or EDM; or treble filters to emphasise details in vocal or classical music. Use the default reference filters to enjoy music with its original sound. Simply unscrew and screw the filters into the housings or provided holder. Wired and Wireless The T20 Wireless is provided with both a 3.5mm connection – compatible with most audio sources – for high-resolution audio; and a flexible wireless neckband. Compatible with the high-fidelity aptX™ codec, and with 12 hours battery, RHA’s SecureFlex neckband enables you to enjoy the T20 Wireless wherever you are, and whatever you’re doing. In-Ear Monitor Unique and distinctive, the stainless steel T20 Wireless housings were designed to fit the ear without fatigue. The shape – achieved using injection moulding – blocks external noise sources, enabling complete immersion in your audio. FAQ What are Tuning Filters? Tuning filters are swappable filters which boost bass or treble frequencies in audio. As well as protecting the IEM from debris entering the sound pipe. What are DualCoil drivers? The DualCoil driver is an upgrade of the industry-standard dynamic driver, with an additional voice coil and custom diaphragm sharing the workload. Delivering focus equally to bass, mid and treble frequencies. Tech Specs Frequency: 20 - 40k Hz Impedance: 16 Ohms Sensitivity: 100dB Max Power: 5mW Bluetooth: 4.1

Review: I am sure that I wrote a review thereon two years ago. - I then said that I was pleased with my purchase. Why are you asking the same question now?
Review: Fantastic - These are simply brilliant. I have purchased loads of good quality headphones and earphones over the years and these are the best so far. Among others, I previously had the wired T20i version which I loved, but wanted wireless options so last year got some B&O E8s which I liked very much as well; they weren’t as good as the T20i though and when I saw these I couldn’t resist. First, they are comfy either in use in ear or dangling they hang neatly and are easy to refit, so I can keep them round my neck all day at work. The sound quality is great, I personally use the bass filters as they add a bit more oomph., but that is a personal view. I also use the foam buds as they stay snug and isolate a lot of outsider noise. The sound is good for music, voice such as radio 4 and calls and so far the call quality is the best I’ve experienced for outgoing calls when out and about. I also like the extended battery life the round the neck band brings. It is also remarkably comfortable. Unlike the E8s the controls are very simple and you don’t get any dropouts or sync issues. Since I’ve had them I’ve also hardly used my Sennheiser Momentum on ears, which surprised me; I’d expected to keep using them when travelling (plane or train).
