{"product_id":"sennheiserhdr175","title":"Sennheiser HDR 175 Replacement Headphone for RS 175-U","description":"\u003cp\u003eThe Sennheiser HDR 175 is the wireless over-ear radio headphone (receiver) of the RS 175-U wireless system and works as a replacement or second headphone for anyone who already owns a TR-175 transmitter.\u003c\/p\u003e\u003cp\u003eImportant up front, and honestly: the HDR 175 is the headphone, not the whole system. To get any sound, you need the TR 175 transmitter - which is included in the complete RS 175-U set.\u003c\/p\u003e\u003ch2\u003eWhy the HDR 175?\u003c\/h2\u003e\u003cp\u003eBecause watching TV together is nicer. Anyone with an RS 175-U pairs a second headphone with the HDR 175 to the same transmitter and shares the film or music - each with their own volume. It's also useful as a replacement once the original headphone has seen better days. The digital transmission stays clear, and the controls sit right on the headphone.\u003c\/p\u003e\u003ch2\u003eWhat you get\u003c\/h2\u003e\u003cp\u003eA closed over-ear headphone with strong bass reproduction, switchable bass boost and two surround modes. Range is up to 100 metres, battery life up to 18 hours. Ergonomic ear pads and a padded headband make long evenings possible without anything pinching.\u003c\/p\u003e\u003ch3\u003eWho is the HDR 175 for?\u003c\/h3\u003e\u003cp\u003eFor owners of an RS 175-U set who need a second headphone or a replacement. Straight talk: if you don't yet have an RS 175-U, buying the HDR 175 alone won't get you a working headphone - then the complete RS 175-U set is the right choice. With the matching transmitter, though, it's a full-fledged, comfortable wireless headphone.\u003c\/p\u003e\u003ch2\u003eOur verdict\u003c\/h2\u003e\u003cp\u003eThe sensible add-on once the base is already in place. As long as you have the TR-175 transmitter, you get a fully-fledged wireless headphone here - not a stripped-down second device.\u003c\/p\u003e\u003ch2\u003eTechnical data\u003c\/h2\u003e\u003cul\u003e\n\u003cli\u003eType: closed over-ear wireless headphone (receiver), dynamic\u003c\/li\u003e\n\u003cli\u003eTransmission: digital, 2.4 GHz\u003c\/li\u003e\n\u003cli\u003eBase required: TR 175 transmitter (included in the RS 175-U set, required separately)\u003c\/li\u003e\n\u003cli\u003eFrequency response: 17 - 22,000 Hz\u003c\/li\u003e\n\u003cli\u003eMax. sound pressure level: 114 dB (1 kHz)\u003c\/li\u003e\n\u003cli\u003eTotal harmonic distortion (THD): less than 0.5 %\u003c\/li\u003e\n\u003cli\u003eRange: up to 100 m (line of sight)\u003c\/li\u003e\n\u003cli\u003eBattery life: up to 18 h\u003c\/li\u003e\n\u003cli\u003eBattery: 2x AAA NiMH\u003c\/li\u003e\n\u003cli\u003eSound features: bass boost, 2 surround modes\u003c\/li\u003e\n\u003cli\u003eDimensions (W x H x D): 21.3 x 11.8 x 20.3 cm\u003c\/li\u003e\n\u003cli\u003eWeight: 310 g (incl. batteries)\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch2\u003eFrequently asked questions\u003c\/h2\u003e\u003ch3\u003eDoes the HDR 175 work without a transmitter?\u003c\/h3\u003e\u003cp\u003eNo. The HDR 175 is the receiver and needs a TR-175 transmitter as a base to get sound. This transmitter is included in the complete RS 175-U set. As a pure replacement or second headphone, the HDR 175 only makes sense if you already own an RS 175-U.\u003c\/p\u003e\u003ch3\u003eCan I use two headphones on one RS 175-U?\u003c\/h3\u003e\u003cp\u003eYes. The TR-175 transmitter supports up to two headphones at once. That way, two of you can watch the same film or listen to the same music, each with their own volume. The HDR 175 is designed exactly for this as a second headphone.\u003c\/p\u003e\u003ch3\u003eIs the HDR 175 compatible with other RS systems?\u003c\/h3\u003e\u003cp\u003eNo, it's matched to the TR-175 transmitter and can't be combined with other Sennheiser wireless systems like the RS 195 or RS 5200. We're happy to confirm in advance which headphone matches your system.\u003c\/p\u003e\u003ch3\u003eWhy buy the HDR 175 from HD Zürisee?\u003c\/h3\u003e\u003cp\u003eBecause with accessories, compatibility is everything - and we check that for you before you order.
