You get a receiver and 2 types of head phones. One is earbuds and the other one goes over your ears. The sound is crisp and clear. The set-up is very easy and simple. This is the best earphone set that I've gotten. My next point is very important. Their customer service is superior. They are so fantastic I wish they would teach and train other companies how to do customer service. If you have any issues whatsoever you can email them and they get back to you asap. They are very friendly and easy to work with. I would rate them an AAA+++. I highly recommend this wireless headset for tv viewing not just because of the quality but also because of the customer service. The price is really good for this device. Review: Great Buy - I bought these about a month ago and it may be helpful to mention that I only used the earbuds and not the headphones so far...The sound quality is great, actually better than I expected compared to what Ive purchased in the past. Really quick connection to your bluetooth; no issues there. I use them for a few hours in the evening and I ususally charge them every other day. They are comfortable for a good hour and a half or so, you need to take a break to let your ears breath for a few and then it's game on again. They do not completely cancel outside noise but they are pretty close. You can't tell unless there is a commercial break, otherwise they are almost perfect. I would recommend these for those who don't want to irritate your spouse with loud tv...*Bonus- sometimes you can't hear other people in the same room ## Features - [Ultimate Wireless TV Watching Set] - The Avantree D4169 contains a Bluetooth Class 1 transmitter and two pre-paired headphones: one (1) in-ear and one (1) over-ear. The aptX LL transmitter delivers <40 ms latency for no lip-sync delay, And, The Avantree D4169 supports TVs with optical (TOSLINK), AUX (3.5mm), RCA audio outputs or built-in Bluetooth audio outputs. Before purchasing, confirm that your TV has one of these options. - [Using With Smart TVs] For Smart TVs with built-in Bluetooth (i.e. 2024 Samsung TV), the D4169 can pair directly via Bluetooth. In this case, slide the transmitter to 'OFF' because there is no need to use the transmitter. - [Personalized Audio] - The D4169 allows you to adjust each headphone’s volume level independently, letting you avoid remote wrestling or clashes over the volume level. Those individuals experiencing hearing can now increase their volume levels without affecting their partners’ TV experience. - [Hassle-free Setup & Long Playtimes] - The headphones and transmitters are factory pre-paired, so the setup is a snap. Once you power on the transmitter and headphones, they’ll connect right away – every time. The in-ear headphones provide up to 20 hours when fully charged, while the over-ear headphone's playtime is up to 40 hours. - [Dual Link - Simultaneous Audio] - Dual Link allows audio to be played through both pairs of wireless headphones simultaneously. However, either headphone can function independently in case only one person is watching TV. Your partner or friend can join you at any time without any audio interruption for you. - [Comfortable and Multifunctional] - The ergonomically designed Avantree D4169’s in-ear and over-ear headphones are to provide all-day comfort. Both wireless headphones have built-in microphones and along with the Bluetooth transmitter can be used with other devices. Use either of the headphones to make a call, listen to your favorite podcast, music, or sporting event, when connected to any Bluetooth-equipped device (mobile phone, laptop). ## Technical Specifications | Specification | Value | |---------------|-------| | ASIN | B08X44NBGN | | Age Range (Description) | Adult | | Audio Driver Type | Dynamic Driver | | Batteries | 2 Lithium Polymer batteries required.

If you would like to get the one that enable them to work simultaneously, you can take HT5009, HT5006, Oasis Plus, and Orbit into consideration. **Q: Can you use with laptop?** A: Yes! The headphones and earbuds can connect to your laptop directly through Bluetooth, or you can plug the transmitter into your laptop's 3.5mm AUX port and use it that way. **Q: Can one person use headphones and another person watch and hear the tv without using headphones?** A: This feature DEPENDS ENTIRELY ON THE TV ITSELF. Even TVs under the same brand can have different results for this matter. When you connect a Bluetooth headphone to your smart TV, OR you connect a wireless audio transmitter to TV via AUX/OPT wire, it often automatically mutes the TV speaker. Some TVs on the other hand, allows simultaneous audio output from their built-in speakers and other output. Unfortunately, most of the time, the only way to find out whether your TV supports simutanenous output - is to try it and see. **Q: how do I know when earbuds or headphones are fully charged?** A: When put the headphones in charge, the LED will turn Red, once fully charged, the RED light will go off.
